Somewhat less famous and a touch more rustic than its neighboring wine-making county, Napa, Sonoma’s viticultural output is no less esteemed — and far more abundant. The county’s nearly 20 official appellations span a diverse gamut of geographies, from the Dry Creek Valley, which yields distinctive Sauvignon Blancs and Zinfandels, to the Russian River Valley and its cool-climate varietals, including many exceptional Pinot Noirs. The largest county in the San Francisco Bay Area, Sonoma comprises gorgeous tracts of ancient redwoods; rugged stretches of coast dotted with seaside hamlets and old Russian forts; and quaint outposts along the Russian River that have drawn flocks of summer revelers since the late 19th century. Healdsburg, a 19th-century agricultural town, is now a charming wine country destination filled with high-end boutiques and hotels focused around a lovely town square. Bodega Bay, a picturesque inlet that straddles Marin County to the south, the setting for Alfred Hitchcock’s “The Birds,” is in reality a rustically romantic village situated on a stunningly beautiful stretch of coast.
