Zinfandel fanatics should try a bottle of Coturri's 1993 Zinfandel Estate and the even more impressive 1993 Zinfandel Philip Coturri Estate Vineyard. Although the 1993 Zinfandel Estate possesses some residual sugar, it is extremely rich, with a huge, black fruit, spice, and roasted herb-scented nose, gigantic body, glycerin, and flavor extraction, and a low acid, off dry finish. It should drink well for 5-6 years. The aging curve suggested for this wine is conservative in view of the fact that no SO2 is used, so Coturri must rely on the wine's high alcohol content for ageability.Intriguing, controversial, but frequently riveting wines are the rule of thumb from this idiosyncratic producer.Tel.
