On the valley floor, with an almost Chateauneuf du Pape layer of small stones, is the Aida Estate, one of my favorite vineyards just north of St. Helena. The 2013 Cabernet Sauvignon Aida Estate is a blend of 92% Cabernet Sauvignon, 5% Petit Verdot and 3% Cabernet Franc aged 20 months in three-fourths new French oak. The good news is that there are 800 cases of this magnificent wine, with a somewhat Graves-like scorched-earth, charcoal, burning ember-scented nose, with notes of hot earth, blackberry and cassis fruit. Big, full-bodied, exuberant and rich, this thick, unctuously textured, purple wine should drink beautifully for 25-30 or more years.
