A Chianti wine is any wine produced in the Chianti region, in central Tuscany, Italy. It was historically associated with a squat bottle enclosed in a straw basket, called a fiasco ("flask"; pl. fiaschi); however, the fiasco is only used by a few makers of the wine now; most Chianti is now bottled in more standard shaped wine bottles. Baron Bettino Ricasoli (later Prime Minister of the Kingdom of Italy) created the Chianti recipe of 70% Sangiovese, 15% Canaiolo and 15% Malvasia bianca in the middle of the nineteenth century.

Sangiovese is a red Italian wine grape variety that derives its name from the Latin sanguis Jovis, "the blood of Jove". Though it is the grape of most of central Italy from Romagna down to Lazio, Campania and Sicily, outside Italy it is most famous as the only component of Brunello di Montalcino and Rosso di Montalcino and the main component of the blend Chianti, Carmignano, Vino Nobile di Montepulciano and Morellino di Scansano, although it can also be used to make varietal wines such as Sangiovese di Romagna and the modern "Super Tuscan" wines like Tignanello.
