The production and conditioning area of the combai chestnuts covers the following municipalities in the Treviso province: Cison di Valmarino, Cordignano, Follina, Fregona, Miane, Revine Lago, Sarmede, Segusino, Tarzo, Valdobbiadene and Vittorio Veneto. The physical and organoleptic characteristics of the Combai Chestnuts are strictly linked to the geographic production environment.
The orography of the territory and the characteristics of the ground are the main reasons that make this area particularly suitable for quality chestnut production. The presence and special qualities of these chestnuts can be found in area from Segusino to Cordignano, with Combai as its centre, confirmed by numerous historical testimonies dating dates back to the XII century.
The historical papers gathered, spanning the period from 1200 to 1700, identifies the Treviso foothills to the left of the Piave as an area naturally suited to chestnut growing, as further confirmed by the many place names. In more recent periods, the value of the Combai Chestnuts has been brought to the fore by the Pro Loco Combai thanks to the Combai Chestnut Festival, which since 1945 constitutes an important event at both a local and national level.
