About Us

Welcome to Fat Grape Winery!

We are a small winery located on Treasure Island in San Francisco, focused on producing hand-made, high quality red wines from locally grown California grapes. Our goal is to make great wine that tastes, smells and truly is all natural, without adding toxic preservatives that other wineries rely on.

We have developed a unique winemaking process that completely avoids the use of sulfites which are typical in nearly all wines found today. The only sulfites which are in our wines come naturally off the vine and from the fermentation process. Our process produces wines that contain from 0ppm to a maximum of 10ppm of sulfites. In most of our wines, the sulfies are undetectable using conventional, industry standard testing methods.

Our Winery is located on Treasure Island in the beautiful city of San Francisco. Treasure Island provides the perfect winemaking environment – cool air from the surrounding bay waters lends itself to naturally keeping wine near it’s optimal storage temperature.

Patrick Bowen has been a home winemaker since 1998. He’s produced small quantity, high quality red wines from grapes grown from all over Northern California. Many of his wines have won numerous awards at harvest fairs, festivals and other competitions.

We hope you can visit soon and enjoy our wines.
