The winery is located in the city of Sonoma in California Sonoma County
(Region North Coast
). It was founded in 1976 when microbiologist Joel Peterson started vinifying wines on a small scale. He was primarily concerned with the wine-growing methods of French Burgundy and Bordeaux. Peterson experimented with it spontaneous fermentation
, long aging on the mash and aging in French barriques, which is still the basis of many wines. He preferred the variety that was very popular in California Zinfandel
, The first Zinfandel wine was harvested in the 200th year of US independence in a thunderstorm with raven cries, which gave rise to the name and the significant logo with three ravens as a ring on the bottle label. Today the winery is owned by the US multinational Constellation Brands
(Centerra Wine Company), Joel Peterson is Senior Vice President.
It mainly produces red wines from the Cabernet Sauvignon, Carignan (Mazuelo), Barbera, Petite Sirah (Durif), Malbec (Cot), Cabernet Franc, Petit Verdot, Merlot, Shiraz and Zinfandel varieties. The few white wines include Chardonnay and Moscato (Muscat Blanc). The grapes are grown by over a hundred Northern California contract winemakers from various AVA areas in Sonoma County Alexander Valley
, Dry Creek Valley, Russian River Valley
and Sonoma Valley, but also from other wine-growing regions such as Lodi
. Mendocino County
and Napa Valley
delivered. The winemakers are like in the management pruning
