 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.
