As the name suggests, Grechetto is an Italian wine of Greek origin. A light, slightly floral white grape from Umbria, it’s ideal for late afternoon, especially if that late afternoon should also be full of bivalves. Pacific Heights wine-and-jazz bar Scopo Divino makes this clear by serving an Argillae Grechetto by the glass ($13) or bottle ($47) alongside its daily dollar-oyster specials.

Oysters remain a singular treat even though we’ve all but collided with the four months out of the year without an R in their name. Modern refrigeration and harvesting techniques have minimized the slack of summertime spawning season, though. So whether you prefer them with Champagne or just a cold beer, we have an updated list — compiled with the generous assistance of Scopo Divino’s Tim Hayman — of dollar-oyster deals in San Francisco and when to find them.
