Backdropped by Union Street's romantic sights, from Gough to Steiner, and Fillmore Street's illustrious shops, from Union to Lombard, the third annual Union Street Has a Crush on You Valentine Wine Walk fills glasses with vine-ripened flavors from around the state and across the world. Although this event is free to the public, pass holders enjoy free access to wine tastings, saving them the trouble of fumbling with billfolds and retina scanners. Participating wineries include Cresten’s Eden Canyon Vineyards, Rosa d’Oro Vineyards, and Terra Sávia, a champion of organic wine. Myriad merchants complement the wine sipping with opportunities for singles or couples to browse such bountiful commodities as organic food and lingerie. Although parking is available downtown, attendants are encouraged to consider public-transportation options so they can leave their cars, trucks, and saddled walruses at home.
