Tuscan wine (Italian Toscana) is Italian wine from the Tuscany region. Located in central Italy along the Tyrrhenian coast, Tuscany is home to some of the world's most notable wine regions. Chianti, Brunello di Montalcino and Vino Nobile di Montepulciano are primarily made with Sangiovese grape whereas the Vernaccia grape is the basis of the white Vernaccia di San Gimignano. Tuscany is also known for the dessert wine Vin Santo, made from a variety of the region's grapes. Tuscany has thirty-three Denominazioni di origine controllata (DOC) and eleven Denominazioni di Origine Controllata e Garantita (DOCG). In the 1970s a new class of wines known in the trade as "Super Tuscans" emerged. These wines were made outside DOC/DOCG regulations but were considered of high quality and commanded high prices. Many of these wines became cult wines. In the reformation of the Italian classification system many of the original Super Tuscans now qualify as DOC or DOCG wines (such as the new Bolgheri label) but some producers still prefer the declassified rankings or to use the Indicazione Geografica Tipica (IGT) classification of Toscana. Tuscany has five sub-categories of IGT wines today.
The history of viticulture in Tuscany dates back to its settlements by the Etruscans in the 8th century BC. Amphora remnants originating in the region show that Tuscan wine was exported to southern Italy and Gaul as early as the 7th century BC. By the 3rd century BC, there were literary references by Greek writers about the quality of Tuscan wine. From the fall of the Roman Empire and throughout the Middle Ages, monasteries were the main purveyors of wines in the region. As the and merchant classes emerged, they inherited the sharecropping system of agriculture known as mezzadria. This system took its name from the arrangement whereby the landowner provides the land and resources for planting in exchange for half ("mezza") of the yearly crop. Many Tuscan landowners would turn their half of the grape harvest into wine that would be sold to merchants in Florence. The earliest reference of Florentine wine retailers dates to 1079 and a guild was created in 1282.
