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.
Sonoma County is not an AVA, but it is a commonly used informal designation for wines made outside of more specific AVAs within Sonoma, which is a large wine producing region just west of Napa Valley. Though Sonoma is often overshadowed by its glamorous neighbor Napa Valley, it has a long history of wine production. The area specialized in jug wine until the mid-20th century, when Sonoma producers took a cue from Napa and started improving quality. Unlike Napa, where Cabernet Sauvignon is king, Sonoma specialized in Chardonnay, Pinot Noir and Zinfandel, though excellent Cabs are produced too. There are at present 16 AVAs within Sonoma County, and, like much of the West Coast of the United States, new AVAs are created in Sonoma County with regularity. Some Sonoma appellations, such as the Russian River Valley, are renowned for Pinot Noir and Chardonnay.
