As black as squid ink, The Black Square is balance personified. A concentrated blackberry aroma seems as dark as the wine's name, with equally dark espresso, olive and charred steak notes joining it in the abyss. A dark plum and ripe boysenberry flavor combo is accompanied by traces of salty Mission olives, wet slate and silky smooth tannins. The one bright feature illuminating the way is the wine's amped-up acidity. None so black.
