From a steep hillside vineyard, the 2007 Zinfandel Jackass Vineyard reveals enormous quantities of pepper, fruitcake, mincemeat, roasted herbs, black and red fruits, a tremendous smokiness, and an unctuous texture with amazing viscosity as well as richness. There are slightly fewer than 400 cases of this beauty, which should drink well for a decade or more.  They are among the fullest-bodied, headiest, most distinctive Zinfandels made in California.
