The Russian River Valley American Viticultural Area (AVA) was established in 1983 and is one of the largest in Sonoma County. Famous for early-ripening varietals, such as Pinot Noir and Chardonnay, the region has a fog-cooled climate and well-drained soils. Chardonnay is the region's most widely grown variety. Today the number of acres in the Russian River Valley devoted to Pinot Noir is estimated at one-third of the total AVA, and is increasing faster than any other variety. The Russian River Valley's cool climate makes the area one of a handful of places in the world where first-class Pinot Noir can be grown.

The AVA's boundaries roughly follow a low-lying plain extending south and west of Healdsburg, following the Russian River toward the Pacific Ocean, and is just fifty-five short miles north up Highway 101 from the Golden Gate Bridge. The Guerneville coastal hills mark its western boundary. J’s vineyards are located along Mark West Creek at the southern end of the Middle Reach, and along Eastside Road in the heart of the Middle Reach, and along Westside Road south of Wohler Bridge.

The appellation has more than 50 wineries, 200 growers, and an estimated 12,000 planted vineyard acres over 150 square miles.
