California Sparkling Wine Regions and Wineries Listed by Region

California sparkling wine producers are grouped by region on californiachampagnes.com, with the listed areas being Sonoma/Marin, Livermore Valley, Napa, Other Northern, Mendocino/Lake, Central Coast, South Bay, and Southern California. Use this list if you want to browse sparkling wine wineries by geography rather than by brand or style. Most California sparkling wine is made in the Méthode Champenoise style, and many producers are found in the cooler California regions.

Regions Listed on the Site

The site organizes California sparkling winery locations into these areas:

The site does not publish a separate winery-by-winery directory in the available page evidence, so treat these as the geographic categories the site uses to organize its coverage.

Why the Regions Cluster Where They Do

According to the site, many sparkling wine producers are found in the cooler California regions. Those producers generally use the same grapes as their counterparts in France — primarily Pinot Noir and Chardonnay, with some Pinot Meunier.

That grape and climate connection is the practical reason the region list matters: if you are looking for Méthode Champenoise-style sparkling wine, the cooler areas are where the site points you first.

How to Use the Region List

1. Pick the region you are traveling to or buying from — for example, Sonoma/Marin or Central Coast.
2. Use that region as your starting filter when searching the site's winery information.
3. Expect the site to keep expanding: it states it is constantly adding information about the California sparkling wine industry.

If you are planning a visit, the region list is the fastest way to narrow down which part of the state to focus on before you look at individual wineries.

What the Site Also Covers

Beyond locations, the site says it provides a knowledge base on accessories, wineries, and information on how to purchase, store, and drink California sparkling wine. It also notes that, unlike the still wine market, sparkling wine sales are largely seasonal and usually linked to celebratory occasions — a stated aim of the site is to change that pattern by making the information easier to find year-round.
