Castello di Grumello is a medieval residence in the heart of Valcalepio, between Bergamo and Lake Iseo. Originally a military fortress with a watchtower, it later became the residence of the condottiero Bartolomeo Colleoni during the conflicts between the Republic of Venice and the Duchy of Milan. It subsequently passed through the hands of several noble families, including the Suardi and the Del Carretto, Princes Gonzaga of Vescovado. It was under the latter that Cabernet Sauvignon was introduced, known locally by farmers as Burdunì.
At weekends, the estate is open by appointment only.
