Concha y Toro, Don Melchor, Puente Alto, Maipo Valley, 2011

With 99% Cabernet Sauvignon and some drops of Cabernet Franc, this comes from the traditional Tocornal Vineyard, planted in the mid-1970s. A cold vintage reveals its herbal, spicy flavours, but above all a crunchy, vivacious acidity and pungent tannins that need time in a bottle. A brilliant version of a classic.
