Bedrock Wine Co. was founded in 2007 in a Sonoma chicken coop. But it’s not an exaggeration to say that Morgan Twain-Peterson, Bedrock’s founder and winemaker, has been in the wine business since birth. His father is Joel Peterson, founder of Ravenswood, the iconoclastic Sonoma producer known for powerhouse Zinfandel, and Morgan began blending his own wine at age five. After college in New York, Morgan worked in various areas of the wine industry before returning to California and starting Bedrock, named for one his family’s vineyards. He sources grapes from Bedrock and other vineyards throughout the region and often seeks out old vine vineyards. Bedrock’s flagship wine is the Bedrock Heritage, usually a blend of mostly Zinfandel and Carignan. Bedrock also makes Zinfandel, Cabernet Sauvignon, Pinot Noir, Sauvignon Blanc and many red and white blends. Reviews have been highly complimentary. Robert M. Parker Jr. has written that Twain-Peterson “has hit the wine scene with a bang, producing vibrant, personality-filled, delicious wines from extremely old vines and, in some cases, virtually unknown grapes, such as Aubun, Teredalgo, Trousseau Noir, Le Noir, Mission, Trousseau Gris, Grand Noir and Abouriou, as well as Zinfandel, Syrah, Petite Sirah, Grenache, Carignan, Alicante Cabernet Sauvignon, Merlot and Tempranillo. Many of these sites are heritage terroirs from the ancient past which, until Peterson's arrival, were largely ignored or were co-mingled into some innocuous industrial blend. Bedrock's portfolio is filled with exciting wines.” Twain-Peterson has earned the distinction of becoming a Master of Wine by successfully completing the rigorous program at The Institute of Masters of Wine. It is one of the mostly highly regarded qualifications in the world of fine wine.
Contra Costa County is a sub appellation within the Central Coast AVA. Contra Costa is the region just to the east of San Francisco, Berkeley and Oakland. Though the area includes many square miles of suburban build-up, there are also vineyards. It is the northern edge of the Central Coast AVA, a huge wine producing area that extends from Santa Barbara County in the south to San Francisco in the north. With more than 100,000 vineyard acres, it includes parts of six counties near the Pacific Ocean. Nearly 20 smaller AVAs lie within the Central Coast AVA. Central Coast earned appellation status in 1985. Included in the appellation are parts of the counties of Contra Costa, Monterey, San Luis Obispo, Santa Barbara, Santa Clara and Santa Cruz. Nearly every grape varietal grown in California is grown somewhere in the Central Coast AVA, though Chardonnay accounts for nearly 50% of the entire wine grape crop.
