Tenuta San Guido is named after the Saint Guido della Gherardesca who lived during the XI century. It is located on the Tyrrhenian coast, between Leghorn and Grosseto, in Maremma an area made famous by Italian Nobel prize winner Giosuè Carducci, and it stretches for 13 km from the sea to the hills. Three are its defining characteristics: the Sassicaia wine, the Razza Dormello-Olgiata thoroughbred studfarm and the Bird Sanctuary Padule di Bolgheri. They divide the estate between the Padule on the coast, the horse's training grounds on the plain, and the vineyards planted up to 350 meters on the hills. The latter have been given their own DOC, the DOC Bolgheri Sassicaia, the first, and so far only case in Italy of a DOC contained in one estate.The wedding of Mario Incisa della Rocchetta and Clarice della Gherardesca on October 18th 1930 started it all. They shared a love for thoroughbred horses that made them form a partnership with horse breeder and trainer Federico Tesio. Mario Incisa's love of good wine made him plant Cabernet vines in 1942 for what was to become Sassicaia. Seventeen years later the Bolgheri Bird Sanctuary becomes Italy's first private nature preserve.
