Treasure Island Wines

An Unique Urban Winery Collective Where Attitude is Past Tense. Founded in 2007 Treasure Island Wines® is the first operational urban winery and tasting room on the former US Naval Base in the middle of San Francisco Bay. Our goal was is to create a place where skilled winemakers craft small batch artisan wines.

TI Wines’ unique and convenient facility is on an island in the middle of San Francisco Bay, centrally located between the Sonoma, Napa, Sierra Foothills, Monterey and Central Coast grape growing regions. Situated in the middle of the Bay, Treasure Island offers an ideal geographic location for wine production, storage and pre-destination staging. In addition, Treasure Island’s year-round naturally cool and humid micro-climate, the location provides an ideal low carbon impact environment for wine making. With its perfect environment and easy access, our winery provides our team not only the flexibility to fulfill their practical needs but to realize their wine making creativity with a green conscience.

The foundation of our winemaking philosophy is that great wines are a result of a healthy relationship between winemaker, grower and the environment. We start by selecting vineyards that are either certified sustainable or organic and prefer to make vineyard designated wines that represent a sense of time and place. When vinified with minimal interventionist methods, the result are wines that faithfully reflects what the vineyard naturally expresses.

We welcome the public during tasting room hours and by appointment. Come meet the winemakers who are eager to share their wines and knowledge with you. While you’re here, you can also experience the best views of San Francisco and Bay Area and some of the unique history of Treasure Island.
