The history of Chianti dates back to at least the 13th century with the earliest incarnations of Chianti as a white wine. Today this Tuscan wine is one of Italy's most well known and recognizable wines. In the Middle Ages, the villages of Gaiole, Castellina and Radda located near Florence formed as a Lega del Chianti (League of Chianti) creating an area that would become the spiritual and historical "heart" of the Chianti region and today is located within the Chianti Classico Denominazione di Origine Controllata e Garantita (DOCG). As the wines of Chianti grew in popularity other villages in Tuscany wanted their lands to be called Chianti. The boundaries of the region have seen many expansions and sub-divisions over the centuries. The variable terroir of these different macroclimates contributed to diverging range of quality on the market and by the late 20th century consumer perception of Chianti was often associated with basic mass-market Chianti sold in a squat bottle enclosed in a straw basket, called fiasco. In addition to changing boundaries, the grape composition for Chianti has changed dramatically over the years. The earliest examples of Chianti were a white wine but gradually evolved into a red. Baron Bettino Ricasoli, the future prime minister in the Kingdom of Italy created the first known "Chianti recipe" in 1872, recommending 70% Sangiovese, 15% Canaiolo and 15% Malvasia bianca. 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. However some producers desired to make Chianti that did not conform to these standards-such as a 100% variety Sangiovese wine, or all red wine grape varieties and perhaps with allowance for French grape varieties such as Cabernet Sauvignon or Merlot to be used. A few producers went ahead and made their "chianti" as they desired but, prohibited from labeling, sold them as simple vino da tavola. Despite their low level classifications, these "super Chiantis" became internationally recognized by critics and consumers and were coined as Super Tuscans. The success of these wines encouraged government officials to reconsider the DOCG regulations with many changes made to allow some of these vino da tavola to be labeled as Chiantis.
