Vin Santo or holy wine comes from the Tuscany region of Italy.
Vin Santo is made from the white Trebbiano and Malvasia grapes. The grapes are dried under the rafters of homes. Vin Santo comes in a wide range of sweetness, from very sweet to very dry, and a wide range of quality. The dry version resembles dry sherry. DOC rules in Italy require at least 3 years of aging and many producers age for at least 5 years.
