Petrolo winery is owned by 4 generations by the Bazzocchi-Sanjust family. The estate extends over 109 acres, 825 to 1,500 feet above sea level, in an area known for prestigious wines since the Renaissance.
The vineyards are set in Val d'Arno Superiore, among the hills of the "Chianti Colli Aretini," bordering southeastern Chianti Classico. The somewhat loosely packed soil features layers of claystone, shale and limestone.
Petrolo aims to produce wines with character and terroir from Sangiovese, Merlot and Cabernet Sauvignon. Today, with 5,500 plants per hectare, production has been reduced to less than 8,000 cases in order to maximize quality. Hand-harvested and fermented in individual lots using native yeasts, the bulk of production is aged in French barriques, though they do employ the use of large oak casks.
Petrolo produces six dry wines and a Vin Santo, but is best known for the 100% Merlot, Galatrona, and the Cabernet-based Il Torrione.
