At the north of the San Francisco Bay Area, Sonoma County is one of the most recognizable wine countries in the New World. Yet it is difficult to pin down an identity for Sonoma wine. Is it the lean and pristine Pinot Noir and Chardonnay of the Sonoma Coast, grown within a stone’s throw of the Pacific Ocean? Or is it their satisfying and singular counterparts found in the Russian River Valley? Or perhaps Sonoma should best be known for its treasured centenarian Zinfandel vineyards, found in patches across the county, or for its structured, savory Cabernet Sauvignon and velvety Merlot.
Of course, Sonoma is all these things and more, and its diversity continues growing as young producers experiment with new varieties and expand the region’s stylistic spectrum. Still, Sonoma can be confusing. The county’s 18 American Viticultural Areas (AVAs) intersect to create a labyrinthine system that is rarely intuitive. Sonoma’s top grape varieties yield wildly divergent results in the hands of winemakers across its 1,800-square-mile expanse. In many regards, Sonoma fits inside one county the entire breadth of the California wine industry.
This guide will explore Sonoma County as well as the other counties of the North Coast: Mendocino County, Lake County, and Solano County. (Napa County is addressed in a separate expert guide.) Despite their proximity, these counties likewise vary in climate and terroir, and their exciting potential is only just being realized.
