A Chianti wine (/kiˈænti/, also US: /-ˈɑːn-/, Italian: [ˈkjanti]) is any wine produced in the Chianti region of central Tuscany. 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 as 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 19th century.
The first definition of a wine-area called Chianti was made in 1716. It described the area near the villages of Gaiole, Castellina and Radda; the so-called Lega del Chianti and later Provincia del Chianti (Chianti province). In 1932 the Chianti area was completely re-drawn and divided in seven sub-areas: Classico, Colli Aretini, Colli Fiorentini, Colline Pisane, Colli Senesi, Montalbano and Rùfina. Most of the villages that in 1932 were suddenly included in the new Chianti Classico area added in Chianti to their name-such as Greve in Chianti which amended its name in 1972. Wines labelled "Chianti Classico" come from the biggest sub-area of Chianti, that includes the original Chianti heartland. Only Chianti from this sub-zone may boast the black rooster seal (known in Italian as a gallo nero) on the neck of the bottle, which indicates that the producer of the wine is a member of the Chianti Classico Consortium, the local association of producers. Other variants, with the exception of Rufina from the north-east side of Florenceand Montalbano in the south of Pistoia, originate in the respective named provinces: Siena for the Colli Senesi, Florence for the Colli Fiorentini, Arezzo for the Colli Aretini and Pisa for the Colline Pisane. In 1996 part of the Colli Fiorentini sub-area was renamed Montespertoli.
