The winery Castello di Bolgheri is the historical nucleus of the winegrowing around Bolgheri. The Castello now belongs to the same family in the 30th generation. Count Federico Zileri Dal Verme is the sole owner of the estate and today he looks after thevineyards and cellars. The wine cellar was built in the middle of the 18th century directly behind the castle. The cultivated areas are located around the wine village in the immediate vicinity of the vineyards of Sassicaia and Ornellaia. The most important wine today is the Castello di Bolgheri Superiore, which is aged in barrels for 24 months.
