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.
Alexander Valley is an American Viticultural Area just north of Healdsburg, in Sonoma County. It was granted AVA status in 1984, with amendments made in subsequent years. The Russian River flows through the valley, and the region was named for Cyrus Alexander, a 19th century landowner and grape grower. The AVA includes 15,000 vineyard acres, much of it rich, alluvial soil layered on a bed of gravel, somewhat similar to many vineyards in Bordeaux. Alexander Valley is sheltered from marine weather by the low hills northeast of Healdsburg, though it is often shrouded in the morning fog coming off the Russian River. Some of the earliest commercial winemaking in the area started in the 1880s, when immigrants formed the Italian Swiss Colony cooperative at Asti. The region made jug wines until the 1960s and 1970s, when a new wave of quality-minded producers started estates. Today Alexander Valley is home to some of California’s most admired wineries, including Simi, Stonestreet and the Francis Ford Coppola Winery. Silver Oak Cellars, though based in Napa Valley, has a second winery in Alexander Valley where it makes Alexander Valley Cabernet Sauvignon. Many grapes do well in the Alexander Valley, including Cabernet Sauvignon, Chardonnay, Merlot, Riesling, Sauvignon Blanc and Zinfandel.
