Rock Wall seems to release its wines pretty young, and this too could use a little time. A blend of half Zinfandel and half Petite Sirah from the obsidian-laden hills of Lake County’s Red Hills area, a very promising spot for Cabernet in particular. Still hugely tannic, this mix is yummy in dusty black fruit, leather and dark chocolate.——V.B.(3/1/2012)—— 87
