The Vallerano chestnuts are grown in the woods surrounding the volcanic hills of Cimini, located in the province of Viterbo. Since chestnut trees thrive in the well-drained soil rich in minerals and organic matter, the densely forested volcanic area around Lake Vico is particularly suitable for their cultivation, which can be traced back to ancient times. Today, chestnuts orchards planted around Cimini cover over 600 hectares of land, and the chestnuts of Vallerano are widely known and prized for their delicate taste.
