Suisun Valley Wine Cooperative: Ninety percent of Suisun Valley's grapes ship to producers in other regions of California. Invariably presided over by one of the five participating winemakers, this co-op housed in a reddish-brown wooden building has tastings featuring free samples of wines made from the fruit left behind, like the albarino produced by King Andrews Vineyards and Mangels Vineyards' syrah-viognier blend called Angelina.
