The backward 2004 Shiraz Heysen, aged 20 months in a combination of American and French oak, possesses a dense purple color as well as rich notes of blackberries, licorice, creosote, and camphor. This dense, full-bodied, ripe, powerful Shiraz includes 5% Cabernet Sauvignon, which is impossible to detect. Give it 2-3 years of cellaring and drink it over the following 12-15+.
