Sonoma County Wine Appellations
There are 19 distinct Sonoma County wine appellations, wine growing regions known as American Viticultural Areas (AVAs). Each has a unique climate and geography and directly correlates to the wine in your glass. From warm, sunny days to cooler, fog covered valley floors, the variations in the geography and climate influence each individual region in many ways.

Located in a section of eastern Sonoma County that is comprised of 500 hillside acres. Home to five wineries and more than 35 vineyards, the AVA is noted for its Bordeaux varietals such as Cabernet Sauvignon, Merlot and Cabernet Franc as well as Syrah and Zinfandel. The area is surrounded by Sonoma Valley and Bennett Valley to the south, Knights Valley and Chalk Hill to the north, and the Russian River Valley to the west. The most remarkable feature of the district is its elevation, up to more than 2,000 feet in some places, as well as a marine influence caused by a gap in the mountains in Santa Rosa.

Rockpile

Russian River Valley
The Russian River Valley climate is sculpted by the regular intrusion of cooling fog from the Pacific Ocean a few miles to the west. The fog arrives in the evening, often dropping the temperature 35 to 40 degrees from its daytime high, and retreats to the ocean the following morning. This natural air-conditioning allows the grapes to develop full flavor maturity over an extended growing season.

Sonoma Coast
The Sonoma Coast AVA extends from San Pablo Bay to the border with Mendocino County. The appellation is known for its cool climate and high rainfall relative to other parts of Sonoma County. Close to the Pacific, with more than twice the annual rainfall of its inland neighbors, it’s warm enough to ripen wine grapes because most vineyards are above the fog line.

Sonoma Mountain
The 2,400-foot Sonoma Mountain range rises above the town of Glen Ellen at the western edge of the Valley of the Moon. These vineyards fall within the larger Sonoma Valley AVA. However, due to the unique hillside terroir, they are entitled to use the more specific designation of the Sonoma Mountain AVA. Powerful, yet elegant Cabernet Sauvignons – the appellation’s specialty – grow here on well-drained soils.
