The 2012 Zinfandel Old Vine Sonoma Valley is composed of 40% Bedrock Vineyard Zinfandel and a kitchen sink blend of five other grapes, the most notable being Carignan, Alicante, Petite Sirah and two obscure grapes called Abouriou and Aubun. It sees about 15% new oak, achieved 14.6% alcohol, and, happily, 1,600 cases were produced. It offers notes of spice, bouquet garni, roasted meats and plenty of red as well as blackberry fruit. The wine displays a wild character, but it is a delicious, medium to full-bodied, very good value that should drink well for 4-6 years. Morgan Twain Peterson, the son of Ravenswood's Joel 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. The 2012s reviewed herein will all be bottled and released by Fall, 2014. Tel. (707) 343-1478
