The original Super Tuscan, Tignanello, is produced exclusively from a 140-acre vineyard site at Antinori's Tignanello Estate. The vineyards are southwest facing, with calcareous rocky-marl and limestone soils with tufaceous elements, locally called alberese rocks. They are planted between 1,150 and 1,312 feet above sea level. It was the first Sangiovese wine to be aged in small oak barrels, the first modern red wine to use such non-traditional varieties as Cabernet in the blend, and among the first red wines from the Chianti Classico area to be produced without white grapes. Since the 1982 vintage, the vineyard and wine blend has been 80% Sangiovese, 15% Cabernet Sauvginon and 5% Cabernet Franc.
