Navigating History: From WWII Navy Simulator to Coastal Tasting Room
The foundation of Sottomarino Winery is built on genuine military history. The tasting room sits inside the concrete and steel structure known historically as the "USS Buttercup," a mock-submarine simulator used by the U.S. Navy during and after World War II to train sailors in damage control and leak repair. Today, instead of rushing water and emergency sirens, the space welcomes guests with low lighting, exposed industrial valves, and a cozy submarine-inspired aesthetic that honors the island's naval heritage.
The winery's name—sottomarino translates to "submarine" in Italian—is a dual nod to the building's physical structure and the winemakers' dedication to Italian grape varietals. By sourcing high-quality grapes from renowned California AVA regions, the vintners craft robust reds and crisp whites that stand up beautifully to the chilly winds of the San Francisco Bay.
Charting Your Course: Tasting Flights, Hours, and Transit Tips
Navigating your way to Treasure Island is easier than ever in 2026, thanks to upgraded public transit infrastructure. The high-speed ferry service from the San Francisco Ferry Building drops visitors off just a short walk from the tasting room gates, allowing wine lovers to bypass weekend Bay Bridge traffic entirely.
Visitors looking to secure a spot on the outdoor patio or inside the historic hull should keep the following tips in mind:
- Book Ahead: Weekend tasting slots fill up quickly, especially during the warm late-summer months of August 2026.
- Try the Flights: The signature tasting flights highlight their award-winning Sangiovese and crisp, refreshing Pinot Grigio.
- Dress in Layers: The Clipper Cove breeze can be notoriously chilly, even when the sun is shining on the outdoor patio.
- Picnics Welcome: Guests are encouraged to bring their own charcuterie or local snacks to pair with the winery's glass and bottle pours.
