After the 1906 San Francisco earthquake left the city in ruins , the California Wine Association moved to '' ' Point Molate ' '' , a promontory on the east shore of San Pablo Bay , and began construction of Winehaven . At the peak of the season , as many as 400 workers lived here , as all of the California Wine Association 's shipments to foreign , coastal and New York markets sailed from the Winehaven dock — shipment capacity was 500,000 gallons ( 1,892,705 liters ) a month , and 40 ships sailed annually for New York alone . The winery was shut down by Prohibition in 1919 , and the company sold off its assets to avoid bankruptcy . Winehaven went mostly unused from about 1920 until the late 1930s
