What is Fermenthings?

Fermenthings is a fermentation-focused learning project built around an open-source wiki. Its stated aim is to be "a place to learn everything about fermentation," and its content mixes recipes, techniques and food-culture writing rather than acting as a shop or a formal academic course.

H3 What you'll find there

The page evidence shows a practical, recipe-led mix:

  • Miso Cookies — using miso as a general ingredient, not just in savoury dishes.
  • Three Ways to Bottle a Summer — ginger bug, elderflower champagne and kombucha.
  • Introduction to Tempeh Making — a guide to growing protein and culturing soybeans.
  • Chinese Cabbage Kimchi (Baechu Kimchi) and Fermenthings' Kimchi Stew — a recipe plus a dish built from aged kimchi and living broth.
  • Master of Spices — chilli, heat and preservation history.
  • Curtido — the Latin American cabbage ferment, framed alongside sauerkraut and kimchi.

H3 Who it suits

It is most useful if you already cook a little and want to move from following a single recipe to understanding a process: why salt ratios matter, how a ginger bug differs from a kombucha culture, or how a ferment can become a broth for another dish. The cultural and historical angles — Java for tempeh, trade routes for heat — make it readable for curious eaters too, not only practitioners. It is not aimed at people wanting industrial food-science data or a structured certification path.

H3 How to use it

Start with one ferment you can taste within a week, such as the ginger bug or a small batch of kimchi, rather than the longer projects. Fermentation is mostly about observation, so keep notes on temperature, salt and timing. If you want a second reference point, Wikipedia covers the microbiology and food-history background of topics like kimchi and tempeh, and Reddit communities such as r/fermentation are useful for troubleshooting a batch that smells or looks wrong.

How do I make tempeh at home?

For a first batch, follow a tested home method rather than improvising ratios. The Fermenthings wiki frames tempeh as an Indonesian technique for turning soybeans into something "nourishing, stable, and deeply satisfying" in a warm, humid climate — which tells you the two things that matter most: preparing the beans properly, and holding them at a steady warm temperature while the mould grows.

Ferment Lab: Fermenthings Open Source Wiki covers tempeh making as an introductory topic, alongside related ferments such as kimchi, ginger bug, kombucha and miso. Use its tempeh page as your starting procedure, and read the kimchi and curtido pages if you want to understand how salted vegetable ferments differ — they rely on salt-tolerant bacteria, while tempeh depends on a mould, so the equipment and hygiene expectations are not interchangeable.

What the process involves

  • Beans: whole soybeans are typical, but the wiki's approach treats tempeh as a general method, so you can also try other beans or grains once you have one batch working.
  • Dehulling and splitting: many home methods crack and skin the beans so the mould can penetrate evenly.
  • Cooking: the beans are cooked through and then dried well on the surface — excess water is a common cause of failure.
  • Inoculation: a tempeh starter containing Rhizopus mould is mixed through the cooled beans.
  • Incubation: the beans are spread in a thin layer, usually in a perforated bag or container, and kept warm for roughly a day or two until the white mycelium binds them into a firm cake.

A practical first attempt

Buy a known tempeh starter rather than trying to grow mould from a previous batch or from the environment — this is where beginners lose batches. Cook, drain and dry the beans until they are cool enough to handle and no longer steaming, then mix in the starter according to its instructions. Pack the beans loosely, no more than a couple of centimetres thick, and incubate somewhere reliably warm. Check after 24 hours: you want even white fuzz and a slight sweet, mushroom-like smell. Black or green patches, or a sour, ammoniac smell, mean discard it.

Trade-offs to expect

Tempeh is faster than many ferments — often ready within a day or two rather than weeks — but it is less forgiving about temperature and moisture. If your kitchen is cool, you will need a warm spot or a simple incubator; if your beans are wet, the mould will struggle. Once you have a reliable batch, the wiki's broader recipe collection shows where tempeh fits: it is a protein base you can then marinate, fry or add to dishes, much as the site treats miso as an ingredient rather than a single soup.

Next step: read the wiki's tempeh introduction in full before buying starter, and note down your incubation temperature and timing for the first batch so you can adjust the second.

What are the best ways to bottle and preserve summer flavors like elderflower and ginger?

For bottling summer flavors at home, the most reliable routes are wild-fermented sodas (ginger bug, elderflower champagne) and kombucha. All three use active cultures to create carbonation instead of added yeast or force-carbonation, so the same skills carry across them.

Ferment Lab: Fermenthings Open Source Wiki groups ginger bug, elderflower champagne and kombucha together as "three ways to bottle a summer," which is a useful framing: one method, three flavor profiles.

Choosing between the three

Method Starter Flavor character Main trade-off
Ginger bug Fresh ginger + sugar, kept active Spicy, gingery, lightly sweet Needs regular feeding to stay alive
Elderflower champagne Wild yeasts on elderflowers Floral, delicate, seasonal Only possible during the short elderflower bloom
Kombucha SCOBY + sweet tea Tart, tea-forward, endlessly variable Requires a ongoing culture and a week or more per batch

Practical guidance

  • Bottle in pressure-safe glass. Fermentation keeps producing CO2 after bottling; use flip-top or thick brewing bottles, never thin decorative glass.
  • Add a little sugar at bottling. This is what the culture consumes to carbonate the drink. Too much plus warm storage equals gushing or broken bottles.
  • Burp and chill. Open bottles briefly every day or two during the first days, then refrigerate once carbonation suits you. Cold slows the culture down.
  • Flavor by infusion, not just syrup. Elderflowers, herbs, fruit and citrus peel can go into the bottle or the primary ferment; Fermenthings' seasonal approach treats the ingredient as the starting point rather than a fixed recipe.

A concrete scenario

You have a jar of ginger bug bubbling on the counter in July and a bag of elderflowers from a weekend walk. Feed the bug, brew a light elderflower infusion, combine, bottle in flip-tops, and check daily. If it over-carbonates, refrigerate immediately and open over a sink. If it stays flat, leave it another day at room temperature.

Next step

Start with one method rather than three. A ginger bug is the lowest-commitment entry point because it needs no SCOBY and no special tea. Once you can reliably carbonate a batch, the elderflower and kombucha versions become variations on a skill you already have.

How can I use miso in sweet recipes beyond soups and marinades?

Miso works in sweets because it adds salt, glutamate and a little fermented complexity that plain salt cannot. In a butter cookie, for example, a spoonful of mild white or red miso deepens the browned-butter and vanilla notes and keeps the biscuit from tasting flat. The page itself makes this point with a miso shortbread-style cookie: once you treat miso as a general ingredient rather than a soup base, it moves easily into baking.

Ferment Lab: Fermenthings Open Source Wiki

H3 Practical ways to use it

  • Cookies and shortbread: cream 1–2 teaspoons of white miso into the butter or dough; pair with brown sugar, chocolate or sesame.
  • Caramel and sauces: whisk a little miso into caramel, butterscotch or a chocolate ganache for a salted-caramel effect without extra salt.
  • Ice cream and custards: add miso to the base before freezing or churning; it rounds out vanilla, roasted sesame or peanut flavours.
  • Fruit bakes and compotes: a small amount with apples, pears or plums mimics the salty-sweet contrast of salted fruit preserves.

H3 Choosing the right miso

  • White (shiro) miso is the safest starting point: mild, sweetish and less likely to dominate.
  • Red (aka) miso is saltier and more assertive; use less and expect a stronger savoury edge.
  • Long-aged or very dark miso can overwhelm delicate cakes, so reserve it for chocolate, caramel or nut-based recipes.

H3 A quick decision rule Start with about 1 teaspoon per 250 g of flour or per cup of custard, taste the raw dough or base, and adjust. If the mixture already contains salted butter, soy sauce or a salty add-in, begin lower. The goal is not to taste miso as miso, but to notice that the sweetness tastes fuller and less one-dimensional.

For a first attempt, take a plain butter or shortbread recipe you already trust and add white miso at that low starting level. If you want a worked example, the miso cookie entry on the wiki is the most direct place to begin.

What is the difference between kimchi, sauerkraut, and curtido?

Kimchi, sauerkraut and curtido are all salted, fermented cabbage traditions, but they differ in seasoning, fermentation style and how they are eaten.

Kimchi (Korean) is typically made with napa cabbage (baechu), salted first, then mixed with a paste that usually includes gochugaru (Korean chili flakes), garlic, ginger, scallion and often fish sauce or salted shrimp. It ferments at cool room temperature or in the fridge, developing a sour, spicy, deeply savoury flavour. It is eaten as a banchan side dish, cooked into stews and fried rice, and used as an ingredient in its own right. The Fermenthings wiki includes both a baechu kimchi recipe and a kimchi stew built on aged kimchi, which shows how the same ferment moves from condiment to cooking base.

Sauerkraut (Central and Eastern European) is usually just cabbage and salt, sometimes with caraway, juniper or bay. The salt draws water from the cabbage, and the cabbage's own lactic acid bacteria do the work. The result is tangy, crunchy and comparatively clean-tasting. It is eaten cold with sausages or potatoes, or cooked with pork, apples and wine. Because it has few added ingredients, it is the easiest of the three for a beginner to make and the easiest to judge by taste alone.

Curtido (Salvadoran) is a lightly fermented cabbage slaw, commonly made with cabbage, carrot, onion, oregano and sometimes chili, covered with salted water or a mild vinegar brine. It is less sour and more fresh-tasting than sauerkraut, and it is usually served as a relish alongside pupusas, grilled meat or beans. The Fermenthings wiki calls it "the Latin cousin of sauerkraut and kimchi," which is a fair short description: the technique overlaps, the seasoning and the role at the table do not.

Kimchi Sauerkraut Curtido
Base Napa cabbage, often radish White cabbage Cabbage plus carrot and onion
Key seasonings Chili flakes, garlic, ginger, fish sauce Salt, sometimes caraway Oregano, mild chili, sometimes vinegar
Ferment character Sour, spicy, funky, complex Sour, crisp, clean Mildly sour, fresh, crunchy
Typical use Side dish, stews, fried rice Side dish, cooked with pork or potatoes Relish for pupusas and grilled food

If you are deciding what to make first, choose by the flavour you actually want rather than by difficulty. Craving heat and umami: kimchi. Want a neutral, versatile ferment that keeps for months: sauerkraut. Feeding tacos, pupusas or grilled meat this week: curtido, since it can be ready in a few days.

A practical next step is to read the Fermenthings kimchi and curtido pages side by side at Ferment Lab: Fermenthings Open Source Wiki and compare their salt and brine ratios, then pick one and keep notes on room temperature, since that variable affects all three ferments more than the recipe wording does.

How do I make kimchi stew with aged kimchi?

Aged kimchi is the right starting point: as it sours, its acidity and deep funk carry into the broth instead of tasting flat. The wiki's own kimchi stew entry describes exactly this situation — a recipe that sat imagined for years until two things came together: a daily miso soup production supplying rich, living broth, and deeply aged kimchi brought by friends. That is a useful pattern to copy even if your kitchen looks nothing like theirs.

The basic move

  1. Render the kimchi. Cut aged kimchi into bite-sized pieces and sauté it in a little oil with its own juice, plus onion if you have it. Let it cook until the edges soften and the smell turns sweet rather than sharp.
  2. Add a living broth. The wiki's version leaned on miso broth; any savoury stock works. Miso, anchovy stock, or a light meat broth all give the stew a base that can stand up to sour kimchi.
  3. Season with restraint at first. Aged kimchi is already salty and acidic. Add gochugaru or gochujang for heat and colour, a pinch of sugar or a splash of the kimchi liquid to balance, and taste before adding more salt.
  4. Simmer with something absorbent. Tofu, pork belly, or mushrooms are common; they soak up the sourness and soften it.
  5. Finish late. Spring onion, sesame oil, or a raw egg stirred in off the heat keeps the top notes intact.

Choosing your kimchi

Kimchi age What it does in stew Best use
Fresh (days old) Crunchy, mild, little acidity Eating raw, as a side
Moderately sour (weeks) Balanced tang, still holds shape Quick stews, fried rice
Deeply aged (months) Strong sourness, soft texture, complex Stew, jjigae, braises

If your kimchi is only mildly sour, the stew will taste thin; add a spoonful of gochujang and simmer longer. If it is very old and very sour, use less of the liquid and balance with a little sugar or a starchy element like potato.

A practical next step

Before cooking, taste a piece of the kimchi on its own. That single bite tells you how much seasoning the pot will need. Then read the wiki's kimchi stew page at Ferment Lab: Fermenthings Open Source Wiki alongside its Baechu Kimchi recipe, so you can see how the same batch behaves raw and cooked. If you are starting from scratch, the kimchi page gives you the fermentation timeline that determines what your stew will taste like weeks later.

How Beginners Can Use the Fermenthings Wiki to Start Fermenting at Home

Start with one project, read the full article before you touch any ingredients, and treat the wiki's background pieces as part of the instructions rather than optional reading. The Fermenthings Open Source Wiki ("A Curious Space for Cultured Things") is a collection of fermentation articles and recipes, and it works well as a beginner's path if you use it in a deliberate order: pick a single ferment, read the whole entry, then expand to related projects once that one succeeds.

What the wiki actually contains

The site describes itself as "a place to learn everything about fermentation," and its published entries mix practical recipes with cultural and historical context. From the visible content, the range includes:

Entry Type What it covers
Introduction to ... Tempeh making Introductory guide Turning soybeans into tempeh; origin on Java, Indonesia
Chinese Cabbage Kimchi (Baechu Kimchi) Recipe The base cabbage kimchi
Fermenthings' Kimchi Stew Recipe A dish built on aged kimchi and living broth
Three Ways to Bottle a Summer: Ginger Bug, Elderflower Champagne & Kombucha Comparative/seasonal guide Three bottled ferments side by side
Miso Cookies Recipe Miso treated as a general ingredient, not just a savoury one
Curtido, The Latin Cousin of Sauerkraut and Kimchi Background + recipe Salted cabbage traditions across cultures
Master Of Spices: Global Heat and The Art Of Spicy preservations Background Chili, spice, preservation, and the history of heat

Two things stand out for a beginner. First, several entries are explicitly framed as introductions (tempeh) or as comparisons (the three bottled ferments), which is exactly what you want before committing to equipment. Second, the wiki repeatedly connects a ferment to its cultural origin — tempeh to Java, kimchi and curtido to salted-cabbage traditions in different regions — so the context is part of the teaching, not decoration.

A beginner path through the wiki

Step 1: Choose one ferment, not five

The "Three Ways to Bottle a Summer" entry is useful precisely because it groups ginger bug, elderflower champagne, and kombucha together — but that grouping is a menu, not a to-do list. Pick one. A single successful batch teaches you more about temperature, timing, and signs of activity than three half-finished jars.

If you want a low-equipment starting point, a salt-based vegetable ferment (the kimchi or curtido entries) needs little beyond a jar, salt, and vegetables. If you want a project with a clear "is it working?" signal, tempeh is instructive because the visible mold growth tells you directly whether conditions were right.

Step 2: Read the entire entry before starting

This matters more than it sounds. The wiki's own kimchi stew entry describes a recipe that "sat in your head for years before it finally happened" and only came together once the right conditions existed — a daily miso soup production supplying living broth, plus deeply aged kimchi from friends. That is a real constraint: some recipes depend on having another ferment already running. Reading to the end tells you whether you need a prerequisite ferment, aged ingredients, or specific equipment before you begin.

Step 3: Note the conditions, not just the ingredient list

Fermentation outcomes depend on temperature, salt concentration, time, and cleanliness. When you read an entry, extract those variables into your own notes before you start:

  • What temperature range does the article assume?
  • How long should the ferment take, and what does "done" look like?
  • What are the signs of normal activity versus a problem?
  • Does the recipe assume a starter from a previous batch?

Step 4: Expand only after one success

Once one ferment works reliably, the wiki's cross-references become useful. Kimchi leads naturally to kimchi stew. A ginger bug leads into the bottled-summer comparison. Miso, once you have it, opens up the miso cookies entry — which makes the point that miso is "much more versatile" once you stop treating it as belonging to a fixed set of dishes.

Why the background articles are worth your time

The wiki's cultural and historical entries — Curtido, Master Of Spices — explain why a technique exists, not just how to repeat it. That matters practically: if you understand that salting cabbage is a preservation method that developed independently in Korea, Latin America, and Europe, you understand the mechanism (salt draws out water, selects for the microbes you want, and acidifies the environment) rather than memorizing one recipe. When a batch behaves unexpectedly, mechanism knowledge is what lets you diagnose it.

The Master Of Spices entry frames heat as something that "travels" along trade routes and through migrations, becoming taste and memory. For a beginner, the takeaway is that spice levels in a ferment are a design choice with a history, not a fixed rule — you can adjust them.

Common sticking points

  • Starting with too many projects at once. The wiki's grouped entries invite this; resist it.
  • Skipping to the ingredient list. Prerequisites like an existing living broth or aged kimchi are easy to miss.
  • Ignoring the "done" criteria. Each ferment has its own visual, aromatic, and textural signals.
  • Treating recipes as fixed. The miso cookies entry explicitly argues for treating an ingredient as flexible rather than tied to specific dishes.

What to do next

Open the wiki, pick the single entry that matches the equipment you already own, and read it start to finish before buying anything. If you have a jar and salt, start with the kimchi or curtido material. If you want a ferment with an unmistakable progress signal, start with the tempeh introduction. Then, and only then, use the bottled-summer comparison to choose your second project.

What Are Open-Source UI Element Libraries and How Do They Differ From UI Frameworks?

An open-source UI element library is a collection of individual, ready-made interface pieces—buttons, cards, inputs, toggles, loaders—that you copy into your own project and adapt. A UI framework, by contrast, is a structured system of components, conventions, and often a theming layer that governs how your whole interface is built. The practical difference: an element library gives you a snippet; a framework gives you a way of working. If you need a polished button in ten minutes, reach for the element library. If you're building a 40-screen product with a team, you probably want the framework.

What "open-source UI element library" actually means

The term gets used loosely, so it helps to separate the parts:

  • Open-source: the code is publicly available, and the license tells you what you may do with it—copy, modify, redistribute, or use commercially.
  • UI element: a single, self-contained piece of interface, usually small enough to read in one sitting. A button with hover states, a pricing card, a search field.
  • Library: a browsable, searchable collection of those elements, typically contributed by many different people.

On a site like Uiverse, elements are shared by a community and written in plain CSS or Tailwind. You find one you like, copy the markup and styles, paste them into your project, and adjust colors, spacing, and text to fit. There's no package to install and no build step required—which is exactly the appeal, and also the source of most of the confusion.

Element library vs. UI framework: the core differences

Dimension Open-source UI element library UI framework / design system
Unit of reuse A single snippet you copy A component you import or call
Installation None; paste into your code Package install, config, sometimes a provider
Consistency Depends on you; each element may look different Enforced by shared tokens and APIs
Theming Manual edits per element Central theme/config file
Updates You own the copy; no upstream updates Version bumps bring fixes and changes
Accessibility Varies per contributor; must be checked Usually tested and documented
Best for Prototypes, landing pages, small sites, one-off needs Multi-page apps, teams, long-lived products
Learning curve Low—read the CSS Higher—learn the API and conventions

The table isn't a verdict. It's a map of trade-offs. Element libraries win on speed and freedom; frameworks win on consistency and maintenance.

Licensing and attribution: what to check before you paste

This is where people get into trouble, and it's worth slowing down for.

  1. Find the license. Every element or collection should state one. Common open-source licenses include MIT, Apache-2.0, and BSD. Some projects use copyleft licenses like GPL, which can impose obligations if you redistribute your code.
  2. Understand what the license permits. MIT and Apache-2.0 are permissive: you can typically use the code in commercial and closed-source projects. Copyleft licenses may require you to release derivative source under the same terms.
  3. Check attribution requirements. Permissive licenses usually require you to keep the copyright notice and license text somewhere in your project. That's a real obligation, not a formality.
  4. Look for per-element terms. On community sites, the site's overall terms and the individual contributor's stated wishes may differ. If a contributor asks for credit, honor it.
  5. When in doubt, ask or avoid. If a snippet has no license at all, you don't have clear permission to reuse it. Treat "no license" as "not open source," even if the code is publicly visible.

This article is general information, not legal advice. For commercial products with real exposure, have someone qualified review the licenses you're relying on.

How to use a community element in your project: a practical workflow

Here's a repeatable process that avoids most of the usual mess.

1. Start from a real need, not a browsing session

Decide what you need first—"a compact primary button with a loading state"—then search. Browsing aimlessly produces a pile of pretty snippets that don't fit together.

2. Copy the smallest version that works

Take the markup and the styles. Strip anything you don't need: demo wrappers, extra animations, decorative layers. Less code means fewer surprises.

3. Convert it to your conventions

If your project uses design tokens or CSS variables, replace hard-coded values:

/* Before: hard-coded */
.button { background: #4f46e5; border-radius: 8px; }

/* After: token-based */
.button { background: var(--color-primary); border-radius: var(--radius-md); }

This one step is what keeps a copied element from looking like a foreign object in your UI.

4. Check accessibility before you ship

Community elements vary widely here. Verify at minimum:

  • Keyboard focus is visible and the element is reachable by Tab.
  • Color contrast meets WCAG AA (4.5:1 for normal text).
  • Interactive elements use semantic HTML (<button>, not a clickable <div>).
  • Form inputs have associated labels.
  • Motion respects prefers-reduced-motion.

5. Test in context

Paste it into a real page with real content. Long labels, small screens, and dark mode break more copied elements than anything else.

6. Note where it came from

Keep a short comment or an internal credits file: source, license, date. Future you—and your legal reviewer—will be grateful.

Where element libraries genuinely shine

  • Prototypes and demos: you need something clickable today, not a design system.
  • Landing pages and marketing sites: a handful of distinctive elements, each custom.
  • Filling gaps: your framework lacks one specific component, and you don't want to build it from scratch.
  • Learning: reading well-made CSS is one of the fastest ways to improve.
  • Small projects: a personal site doesn't need a theming architecture.

Where they fall short

  • Consistency at scale: ten elements from ten contributors rarely look like one product.
  • Maintenance: you own every copy. When your design changes, you edit each one.
  • Accessibility debt: you inherit whatever the contributor did or didn't do.
  • No upstream fixes: a bug fixed in the original won't reach your copy.
  • Integration friction: different naming conventions, different units, different assumptions about resets.

When to choose which

Choose an element library when the scope is small, the timeline is short, or you need a few distinctive pieces rather than a whole system.

Choose a framework or design system when multiple people build multiple screens over months, when consistency is a product requirement, or when accessibility and theming need to be guaranteed rather than checked.

A hybrid works well for many teams: adopt a framework for the structural components—forms, navigation, layout—and borrow individual elements for the places where you want personality. Just route every borrowed element through the same token and accessibility checks, so it lands as part of your system rather than beside it.

The short version: open-source UI element libraries are a fast, flexible way to get good-looking interface pieces into a project. They are not a substitute for a design system, and the license and accessibility details are the part worth reading carefully.

What "Open Source" Means for the Fermenthings Fermentation Wiki

"Open source" on the Fermenthings wiki describes how the site presents and shares its fermentation knowledge rather than a software license you can look up in a code repository. The wiki publishes its articles and recipes openly, so anyone can read them, learn from them, and apply the techniques at home. What it does not automatically tell you is the exact legal terms for reusing or republishing the text and images — those terms live on the site itself, and you should check them before copying content elsewhere.

What the site actually is

Ferment Lab: Fermenthings Open Source Wiki describes itself as "a place to learn everything about fermentation" and frames its collection as "a curious space for cultured things." It is a knowledge-sharing project built around written articles and recipes, not a product with a paywall or account requirement described in the available material.

The content is organized as individual posts, each covering one fermentation project or idea. Examples visible on the site include:

  • Miso Cookies — treating miso as a general ingredient rather than something limited to soups and marinades
  • Three Ways to Bottle a Summer — ginger bug, elderflower champagne, and kombucha
  • Introduction to Tempeh Making — tempeh's origins on Java and its role in preserving soybeans in a warm, humid climate
  • Chinese Cabbage Kimchi (Baechu Kimchi)
  • Fermenthings' Kimchi Stew
  • Master of Spices — chili, heat, and the history of spicy preservation
  • Curtido — described as the Latin cousin of sauerkraut and kimchi

Each entry mixes practical method with context: where a ferment comes from, why it developed, and how the technique fits into a broader food tradition.

What "open source" means here

In practice, an open-source wiki usually implies three things:

Dimension Typical meaning What to verify on the site
Access Content is publicly readable without a special invitation Whether any pages are restricted
Collaboration Readers may be able to contribute, correct, or extend entries Whether an edit or submission route exists
Reuse Material may be shared or adapted The specific license or usage terms stated

The first two are the spirit of the project. The third is where you should not assume. "Open source" in common usage suggests reusability, but the actual permissions — whether you can republish a recipe on your own site, translate it, or use photos commercially — depend on the terms the site publishes. Read those before reusing anything.

Why open sharing matters for fermentation

Fermentation knowledge has always spread through sharing. The wiki's own framing reflects this: heat "travels" along trade routes and through migrations, and cabbage salting appears independently in Korean kimchi, Latin American curtido, and European sauerkraut. An openly readable collection continues that pattern — a home fermenter in one country can follow a technique documented from another, test it, and feed observations back.

For a beginner, this means you can start with a single recipe, learn the underlying principle, and then adapt it. For someone with experience, it means the collection works as a reference to compare traditions rather than a fixed rulebook.

How to use the wiki

  1. Pick one project that matches what you have. If you have cabbage, start with kimchi or curtido. If you have soybeans, look at the tempeh introduction.
  2. Read the full entry, not just the ingredient list. The context sections explain why steps matter, which helps when your conditions differ from the author's.
  3. Check the site's own terms if you plan to republish, translate, or reuse images.
  4. Treat dates as a signal. Entries carry publication dates, so you can see how recently a topic was covered.

The main limitation to keep in mind: an open wiki reflects its contributors. Coverage is uneven, and a topic you need may be thin or missing. Where an entry is detailed, it tends to be because someone documented a process they actually worked through — which is usually the most useful kind of fermentation writing.

What Fermentation Topics and Recipes Can I Find on the Fermenthings Wiki?

The Fermenthings wiki (wiki.fermenthings.be) is an open-source fermentation knowledge base that mixes practical recipes with the culture and science behind them. Based on the articles currently visible on the site, you can find content spanning miso, tempeh, kimchi, fermented drinks, and Latin American cabbage ferments — each written as a dated article rather than a standardized database entry. The exact catalog changes over time, so treat the list below as a snapshot of what the wiki covers, not a fixed index.

What kinds of content does the wiki publish?

The site describes itself as "a place to learn everything about fermentation" and "a curious space for cultured things." Two content types appear consistently:

  • Recipes with a specific angle — e.g., miso cookies, kimchi stew, or three different bottled summer drinks.
  • Explanatory and cultural articles — e.g., the history of chili and preservation, or how cabbage fermentation travels across cultures.

Articles carry publication dates and thematic titles, so you can browse chronologically or by topic. The writing tends to connect a technique to a broader story rather than just listing ingredients.

Fermentation categories covered

Miso and umami-forward ferments

The wiki's miso content goes beyond soup. One article, "Miso Cookies: When Umami Meets the Shortbread Biscuit," argues that once you treat miso as a general ingredient rather than something tied to savory dishes, it becomes far more versatile — with a butter cookie as the example. This is useful if you already make miso and want non-traditional uses.

Tempeh

"Introduction to ... Tempeh making" frames tempeh as fermentation "doing exactly what it is meant to do: transform simple ingredients into something nourishing, stable, and deeply satisfying." It notes tempeh originated on the island of Java in Indonesia as a way to preserve soybeans in a warm, humid climate. Expect a foundational introduction rather than an advanced troubleshooting guide.

Kimchi and cabbage ferments

Cabbage fermentation is a recurring theme:

  • Chinese Cabbage Kimchi (Baechu Kimchi) — a dedicated recipe article.
  • Fermenthings' Kimchi Stew — a recipe built on aged kimchi and living broth, described as an idea that took years and the right conditions to realize.
  • Curtido — presented as "the Latin cousin of sauerkraut and kimchi," a story of cabbage, culture, and quiet fermentation.

If your interest is salted-cabbage ferments across cultures, this is the strongest cluster on the site.

Fermented drinks

"Three Ways to Bottle a Summer: Ginger Bug, Elderflower Champagne & Kombucha" groups three drink projects around a single question: how do you capture a season in a bottle? The article ties this to the broader human practice of preserving abundance through drying, salting, smoking, or fermenting. This is a good starting point if you want carbonated, low-equipment ferments.

Spices, heat, and preservation

"Master Of Spices: Global Heat and The Art Of Spicy Preservations" explores chili, spice, and the history of heat — how capsaicin, sanshool, and isothiocyanates become taste, culture, and memory as they move along trade routes and across generations. This is background reading rather than a step-by-step recipe.

How to use the wiki

  1. Start from a category you already cook. If you make cabbage dishes, the kimchi and curtido articles connect directly to what you know.
  2. Read the framing before the recipe. These articles often explain why a ferment works before telling you what to do, which helps when you adapt a recipe to your own ingredients.
  3. Check the date. Articles are dated (the visible ones range from late 2025 into 2026), so newer posts may reflect updated methods.
  4. Verify current coverage on the site itself. The visible article list is a sample; the wiki may add or reorganize topics, and no pricing or login requirements are stated in the available material.

If your interest is a specific ferment not listed here — say, koji, vinegar, or dairy — confirm it exists on the site before assuming coverage, since the evidence only supports the categories above.

What is Ferment Lab: Fermenthings Open Source Wiki?

Ferment Lab: Fermenthings Open Source Wiki is an open-source fermentation knowledge wiki published by Fermenthings, described as "a place to learn everything about fermentation." It is a reference and recipe space for people who want to make fermented foods at home or understand the culture and history behind them. The site is in English, and its visible content mixes practical recipes, step-by-step guides, and longer cultural essays rather than acting as a single-subject blog.

What the site covers

The homepage presents itself as "A Curious Space for Cultured Things." Its visible entries span several fermentation traditions and formats:

  • Miso — including a recipe that treats miso as a general ingredient, such as miso cookies where umami meets a shortbread biscuit.
  • Tempeh — an introduction to tempeh making, framed as "growing protein, binding culture," with its origins on the island of Java in Indonesia.
  • Kimchi — a Chinese cabbage kimchi (baechu kimchi) recipe, plus a kimchi stew that uses aged kimchi and a living miso broth.
  • Kombucha and other bottled ferments — a piece on bottling summer with ginger bug, elderflower champagne, and kombucha.
  • Chili and spice preservation — an exploration of chili, spice, preservation, and the history of heat.
  • Curtido — described as the Latin cousin of sauerkraut and kimchi, a salted cabbage ferment.

What kind of content to expect

The entries are not limited to ingredient lists and timings. They typically combine:

  1. Recipes — concrete preparations such as miso cookies, baechu kimchi, or kimchi stew.
  2. Guides — instructional introductions, for example to tempeh making.
  3. Cultural and historical context — essays on how heat travels along trade routes and migrations, or how salting cabbage became kimchi in Korea and curtido in Latin America.

This mix means the wiki works both as a place to follow a method and as background reading on why a ferment exists in a given cuisine.

Who it is for

It suits home fermenters, cooks curious about fermentation beyond a single recipe, and readers interested in the food-culture side of preservation. Because the content is open source and organized as a wiki, it is also relevant to anyone who wants to see how a fermentation knowledge base is structured, or who might want to contribute to one.

Practical notes

The visible pages are dated, with entries running from late 2025 into 2026, so the wiki is actively added to rather than archived. The site does not display pricing or login requirements in the material available here; treat access and any contribution rules as things to confirm on the site itself rather than assuming they are free or open to edit.

Website Overview

Identifiable technologies and additional version or configuration signals make the service easier to fingerprint, which may help targeted scanners narrow their checks. Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.

Domain and Registration

The domain uses the common .be extension, which is not an independent safety signal.

DNS and Email

Nameservers are provided by combell.eu, indicating managed DNS hosting. MX records point to the mailprotect.be email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Microsoft. Such markers may also remain after a service stops being used.

TLS and Certificates

The certificate uses an RSA 4096-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.

HTTP and Browser Security

The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header identifies nginx without an exact version. No explicit CDN or WAF marker was found in the response headers.

Technology Stack Analysis

The public page identifies WordPress 6.7.9, jQuery, nginx, with exact versions exposed for 1 technologies. These details can narrow vulnerability checks, although exposure alone is not a vulnerability.

Search and Social Sharing

The title has 91 characters and may be truncated in search results. The Generator tag identifies WordPress 6.7.9, making the publishing system easier to fingerprint. Open Graph is partially configured; og:image is missing. Twitter Card metadata is configured. The page declares 3 language or regional alternatives using hreflang.
