Giacomo Tachis was an Italian oenologist, known as the father of Super Tuscan wines.
Born in Poirino, Piedmont, in 1954 Tachis graduated from the Enological School of Alba, and in 1961 he was chosen as junior oenologist at Antinori's San Casciano in Val di Pesa cellars in Tuscany. He soon became the director, and his commitment with Antinori lasted 32 years.
During his career, Tachis collaborated on creating new genres of Italian red wine, for exepmple Sassicaia, Solaia and Tignanello, San Leonardo and Turriga. He made innovative choices for his time, such as exceeding the area specification for Chianti Classico, using the malolactic fermentation and using barriques for the aging periods, so that the barrique "became one of the symbols of the Italian wine renaissance". In addition to wines he created, he promoted and collaborated to the production of several other wines, including the Sardinian Vermentino and Carignano, the Sicilian Nero d'Avola, Inzolia, Cataratto and Grillo, the Piedmontese Barbera and Nebbiolo, Lambrusco from Reggio Emilia and Sangiovese from Tuscany.
In 2011 the magazine Decanter named Tachis as their "Man of the Year".
