The original Super-Tuscan, Tignanello is produced exclusively from the Tignanello vineyard, a 47 hectares (116 acres) southwest-facing, calcareous rocky-marl and limestone soil plot with tufaceous elements, planted between 1,150 and 1,312 feet above sea level at Antinori's Santa Cristina Estate. It was the first Sangiovese to be aged in small oak barrels, the first red wine in modern times to use a non-traditional grape variety, Cabernet, in the blend, and among the first red wines made in Chianti with no white grapes. In all three instances, it set the example for a new breed of exceptional top-of-the-line Italian wine. Tignanello, originally a Chianti Classico Riserva labeled Vigneto Tignanello, was first vinified as a single vineyard wine in the 1970 vintage, when it contained 20% Canaiolo and 5% Trebbiano and Malvasia, and was aged in small oak cooperage. With the 1971 vintage the wine became a Vino da Tavola della Toscana and was named Tignanello after the vineyard from which it originates. Beginning with this vintage, Tignanello stopped adhering to the rules laid down by Chianti Classico Disciplinare, and with the 1975 vintage, white grapes were totally eliminated.
