I have written in detail about the idiosyncratic wines from this small winery tucked on the Sonoma Mountain hillside. Some offerings can be problematic, but when everything goes right, Coturri makes some of the richest, most distinctive, personality-filled wines, particularly the Zinfandels, available in California. For example, the 1995 Zinfandel Sonoma Mountain (15.8% alcohol) is a dense purple-colored wine, with a gorgeous nose of jammy cherries and raspberries. The wine is highly-extracted and rich, with loads of glycerin, full body, and considerable purity. Drink this thick, nearly unctuous Zinfandel over the next 5-6 years. This winery bottles its offerings in small lots, so let's hope all the bottles taste as excellent as this. Tel. (707) 996-6247
