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 R?fina. 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.[2][3]?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.
