My least favorite is the 2007 Cabernet Sauvignon Marston Vineyard, which seems sinewy, austere, lean and tannic, but offers excellent aromatics as well as a good attack before it narrows in the mouth. As always, Beringer sells all their single vineyard Cabernet Sauvignons that make up the blend for the Private Reserve to their VIP customers at the winery or through their mailing list. Interestingly, each year when I taste through these wines, the sum of the individual parts is always the best wine. In short, the Private Reserve always seems to outscore and show more complexity than most of the single vineyard Cabernets. Nevertheless, it is an exercise in single vineyard terroirs and is an interesting process. Usually there are around 250 cases of each of these single vineyard offerings. The single vineyard offerings are all noteworthy, and analytically, they are more similar than dissimilar. The alcohols range from a low of 14.5% to 14.9%. Not surprisingly, one of my favorites, the Bancroft Ranch, was the largest component part of the Private Reserve. Tel. (707) 963-7115; Fax (707) 963-1735
