The 2015 Cornas Vin Noir, from 100-year-old vines, is a tour de force. Crushed stone and violets set the stage for this full-bodied wine that’s loaded with cassis and plum fruit but hemmed in tightly by firm tannins. Give it at least 7 years of rest in a cool cellar. At the caveau price of 40 euros, it’s a bargain.
