The Tenuta Tignanello estate is in the heart of Chianti Classico, in the gently rolling hillsides between the Greve and Pesa river valleys. It extends over an area of 319 hectares (788 acres), of which 127 (313 acres) are dedicated to vines. Two of the estate?s prized vineyards are on the same hillside, Tignanello and Solaia, on soils that originated from marine marlstone from the Pliocene period rich in limestone and schist. The vines enjoy hot temperatures during the day and cooler evenings throughout the growing season. The estate?s two signature wines, Solaia and Tignanello, are produced from these vineyards and have been defined by the international press as ?among the most influential wines in the history of Italian viticulture?. According to Marchesi Antinori, Solaia and Tignanello are an ongoing challenge and a never-ending passion. The Tignanello estate has vineyards of indigenous Sangiovese grapes as well as some other untraditional varieties such as Cabernet Franc.
