According to the importer, this red Vermouth is produced with Arneis, Cortese, Trebbiano and Barbera d’Asti grapes with a diverse mix of herbs and spices that soak in the spirit for a minimum of 60 days according to a recipe developed by the Quaglia family in the 1930s. The distillery was founded in 1890 and the current owners purchased it in 1906. Berto's red and white vermouths are described as "standard-bearers of traditionally and artisanally produced sweet vermouth from Piedmont."
