Chianti is a region in Italy (as well as the name of the wine variety produced there) and encompasses vast areas of the city of Tuscany. The Chianti region was first defined in 1716 and was later redefined in 1932 to encompass a far more vast area. Wines from the original are referred to a Chianti Classico and are the most revered of the Chianti varieties. In order for a wine to be considered true Chianti, it must be made from at least 80% Sangiovese grapes and typically is also made of 10% Canaiolo and up to 20% of an approved red grape variety.
