Made from 100% Syrah, the 2015 Syrah Powerline Vineyard is much more backward, brooding, and mineral-laced, with sensational notes of blackcurrants, cassis, crushed rock, and tapenade. A true powerhouse on the palate, with terrific concentration, building tannin, and a great, great finish, it's a singular, incredible wine that does everything right. Give bottles 2-3 years and enjoy over the following decade.
