Rattlesnake Hill is on the estate, more than 2,000 feet up in the Mayacamas above St. Helena. Typically tannic, in the way of Spring Mountain Cabs, the ’05 is a dramatically structured wine that dazzles with power. Made entirely from Cabernet Sauvignon, it shows classic varietal flavors of black currants, cherries, licorice and spices, while mostly new French oak adds the perfect facade of smoky wood. Fabulous now with decanting and over rich fare such as steak, the wine should age gracefully for at least a decade.——S.H.(6/1/2008)—— 95
