San Casciano in Val di Pesa is a comune (municipality) in the Metropolitan City of Florence in the Italian region Tuscany, located about 15 kilometres (9 mi) southwest of Florence.

Chianti is an Italian red wine produced in the Chianti region of central Tuscany, principally from the Sangiovese grape. It was historically associated with a squat bottle enclosed in a straw basket, called a fiasco. However, the fiasco is now only used by a few makers of the wine; most Chianti is bottled in more standard-shaped wine bottles. In the latter nineteenth century, Baron Bettino Ricasoli helped establish Sangiovese as the blend's dominant grape variety, creating the blueprint for today's Chianti wines.
