Notes Abacus is ZD's ultimate Cabernet Sauvignon, combining the best qualities of an aged wine with the best of a youthful wine, together in one sumptuous mouthful. Incredible depth and complexity along with a deep, lingering finish are backed by an intense fruit character. This is a "solera style" multiple-vintage blend of every ZD Reserve Cabernet Sauvignon ever produced, which is held in barrel until bottling.
