About TIW

Treasure Island Wines

Treasure Island Wines® is a Unique Urban Winery Collective Where Attitude is Past Tense. Founded in 2007 by the Mirowski Brothers, Treasure Island Wines is the first operational urban winery and tasting room on Treasure Island which formerly served as a US Naval Base in the middle of San Francisco Bay. We designed the facility to create a sanctuary where we could produce our small batch artisanal wines and invite like minded winemakers to join in the wine synergy.

TI Wines’ also provided a unique and convenient location 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 from where we could source the finest fruit and be easily accessible to residents and visitors to the Bay Area. Situated in the middle of San Francisco Bay, with some of the most photographed views of the City, 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 utilizing green methodology.

The foundation of our winemaking philosophy is that great wines are a result of a healthy relationship between the winemaker, growers and the environment. We start by selecting vineyards that are either certified sustainable / 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 that is, Treasure Island.
