named after the redwood tank where the first riboli family vintners stored their best wine a century ago, this blend of 50% cabernet sauvignon, 20% merlot, 16% petit verdot and 14% malbec shows blueberry and slate minerality on the nose, alongside licorice and mint spices. the palate is overwhelmed by tannins, though black pepper, tobacco and charred meat flavors emerge.
