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 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 on the neck of the bottle
Other variants, with the exception of Rufina from the north-east side of Florence and 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.
