I am sure there must be more to the 1992 Grand Reserve than the 1992 Vintner's Reserve. Although they are clearly different, I liked them equally as much. The 1992 Zinfandel Grand Reserve exhibits more spice, tannin, and body, but I did not enjoy it any more than the lower-priced Vintner's Reserve. Well-made, with plenty of cherry fruit, a saturated color, and fine depth, it should be drunk over the next 4-5 years. Tel. (707) 263-9333
