Northern Sonoma Wine Region and Appellation

Share this story

The Northern Sonoma wine region may seem like a puzzler: Although very few wineries use the appellation on wine labels, it is neither small nor obscure. It is, in fact, the answer to a puzzler.

The second-largest AVA within Sonoma County after the Sonoma Coast, Northern Sonoma combines the better part of six other major viticultural areas.

The few wineries that do use Northern Sonoma for estate-grown Cabernet Sauvignon, Chardonnay, and other wines are household names making Sonoma County wines available in markets across the nation.

AVA status for the 329,000-acre Northern Sonoma appellation was established in 1990.

Top Grapes 

Alexander Valley

Most every grape variety grown in Sonoma County is also grown in Northern Sonoma; currently, wines bearing the appellation include Cabernet Sauvignon, Chardonnay, Zinfandel, and Sauvignon Blanc.

The Lay of the Land

Northern Sonoma combines Dry Creek Valley, Alexander Valley, Knights Valley, Chalk Hill, Russian River Valley, and Green Valley. Elevations range from valley floors to mountain peaks.

In viticultural terms, the AVA is only useful to distinguish this broad area from the Sonoma Valley, Carneros, and western part of the large Sonoma Coast AVA.

It was established to solve a quandary: Wineries may only use the word 'estate' on their label if both the winery and vineyards that they own or farm are located in the same AVA. When the E&J Gallo company, which makes a large portion of wine sold in the U.S. and was the driving force behind the Northern Sonoma petition, sought the premium 'estate' designation for their Gallo of Sonoma brand (now Gallo Family Vineyards), they could only do so when their wide-ranging vineyards fit into the newly-designated, composite AVA.

Notable Wineries 

In addition to Gallo Family Vineyards' Estate Cabernet Sauvignon and Chardonnay, Rodney Strong Vineyards uses the Northern Sonoma appellation on its popular Knotty Vines Zinfandel and Charlotte's Home Sauvignon Blanc.

Backroad Bodegas

Finding small wineries that use the Northern Sonoma AVA might make for a futile scavenger hunt challenge. But there are many that offer estate-grown varietal wines within this area. While traveling through the northern part of Northern Sonoma, just south of the sweeping vineyards of the Asti area, seek out Cabernet Sauvignon, Zinfandel, and interesting historical perspectives at J. Rickards Winery.

In the Russian River Valley, Bacigalupi Vineyards has helped to make Sonoma County Chardonnay famous in their own quiet, behind-the-scenes way.
