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 immediately or later in Chianti to their name-such as Greve in Chianti which amended its name in 1972. Wines labeled Chianti Classico come from the biggest sub-area of Chianti, that sub-area that includes the old Chianti area. The 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.

During the 1970s producers started to reduce the quantity of white grapes in Chianti. In 1995 it became legal to produce a Chianti with 100% Sangiovese. For a wine to retain the name of Chianti, it must be produced with at least 80% Sangiovese grapes. M. Ewing-Mulligan & E. McCarthy Italian Wines for Dummies pg 147-159 Hungry Minds 2001 ISBN 0764553550 It may have a picture of a black rooster (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 "Gallo Nero" Consortium; an association of producers of the Classico sub-area sharing marketing costs. Since 2005 the black rooster is the emblem of the Chianti Classico producers association. Aged Chianti (38 months instead of 4-7), may be labeled as Riserva. Chianti that meets more stringent requirements (lower yield, higher alcohol content and dry extract) may be labeled as Chianti Superiore. Chianti from the "Classico" sub-area is not allowed in any case to be labeled as "Superiore".

History

Main: History of Chianti The earliest documentation of a "Chianti wine" dates back to the 13th century when viticulture was known to flourish in the "Chianti Mountains" around Florence. The merchants in the nearby townships of Castellina, Gaiole and Radda formed the Lega del Chianti (League of Chianti) to produce and promote the local wine. In 1398, records note that the earliest incarnation of Chianti was as a white wine. In 1716 Cosimo III de' Medici, Grand Duke of Tuscany issued an edict legislating that the three villages of the Lega del Chianti as well as the village of Greve and a 2 mile (3 km) hillside north of Greve near Spedaluzza as the only officially recognized producers of Chianti. This delineation existed until the 1930s when the Italian government expanded the zone. Subsequent expansions throughout the 20th century would eventually bring the Chianti zone to cover almost all of Tuscany. The original zone dictated by the edict of Cosimo III de' Medici would eventually be considered the heart of the Chianti Classico region. A. Domine (ed.) Wine, pp. 402-411, Ullmann Publishing, 2008 ISBN 9783833146114 left|thumb|The Italian statesman Bettino Ricasoli developed the first "modern" Chianti recipe that was Sangiovese based. By the 18th century, Chianti was widely recognized as a red wine but the exact composition and grape varieties used to make Chianti at this point is unknown. Ampelographers find clues about which grape varieties were popular at the time in the writings of Italian writer Cosimo Villifranchi who noted that Canaiolo was widely planted variety in the area along with Sangiovese, Mammolo and Marzemino. It wasn't till the work of the Italian statesman Bettino Ricasoli that the modern "Chianti recipe" as a Sangiovese based wine would take shape. H. Johnson Vintage: The Story of Wine pg 414-420 Simon and Schuster 1989 ISBN 0671687026 Prior to Ricasoli, Canaiolo was emerging as the dominant variety in the Chianti blend with Sangiovese and Malvasia playing supporting roles. In the mid-19th century, Ricasoli developed a recipe for Chianti that was based primarily on Sangiovese. His recipe called for 70% Sangiovese, 15% Canaiolo, 10% Malvasia (later amended to include Trebbiano) and 5% other local red varieties. In 1967, the Denominazione di origine controllata (DOC) regulation set by the Italian government firmly established the "Ricasoli formula" of a Sangiovese based blend with 10-30% Malvasia and Trebbiano.
