 Although the initial blend did not yet contain any Cabernet Sauvignon or Cabernet Franc, no white grape varieties were used, which meant that the wine was ineligible for the Chianti Classico appellation; from the vintage 1975 onwards the blend contained Cabernet Sauvignon.Technically Tignanello was not the first 'Super Tuscan' – that honour goes to Sassicaia, created by a relative of the Antinoris, the Marquis Mario Incisa della Rocchetta – even though the Antinoris were experimenting with Cabernet blends since the 1920s.But it was Tignanello that really shook up the Italian wine industry, leading to far-reaching changes in rules and attitudes.
