Notes from Selvapiana:

"Vin Santo is one of those Old World wines that no modern winemaker would ever imagine making if the concept hadn't been devised and proven centuries ago. Taking perfectly good grapes, drying them out for a few months until they become raisins, sealing them up in a little barrel, and then waiting several years to see if anything drinkable comes out . . . is not what they teach in enology classes today. Nevertheless, whether by accident or on purpose, people did it long ago, and the result if you do it right turns out to be a delicious unctuous sweet wine called Vin Santo. These wines are made all over Tuscany, but one of the best places to do it is here in the Rùfina subzone of Vin Santo del Chianti DOC."
