Solaia is a 50 acre (20 hectare), southwest-exposed vineyard of the Tignanello estate situated between 1150 and 1320 feet (350-400 meters) above sea level on stony soils consisting of calcareous clays and limestone rock. The Marchesi Antinori produced this wine for the first time in the 1978 vintage with a blend consisting of 80% Cabernet Sauvignon and 20% Cabernet Franc, repeating the initial production in 1979. In the following vintages, 20% Sangiovese became part of the blend and adjustments to the ratio of Cabernet Sauvignon and Cabernet Franc were made until the current composition of the blend was defined. Solaia is produced only in top vintages and was not produced in 1980, 1981, 1983, 1984, or 1992.
