Tuscany hosts some of the most important wine areas in the world. Chianti, Brunello di Montalcino and Vino Nobile di Montepulciano are mainly produced with Sangiovese grapes while Vernaccia grapes are the basis of the white Vernaccia of San Gimignano. Tuscany is also known for its Vin Santo dessert wine, made from a variety of grapes from the region. Tuscany has 33 Denominations of controlled origin (DOC) and 11 of Controlled and Guaranteed Origin (DOCG). In the 70s a new class of wines emerged known in the sector as "Super Tuscans". These wines were produced outside the DOC / DOCG regulations but were considered high quality and had high prices. Many of these wines have become cult wines. Super Tuscan now qualify as DOC or DOCG wines (like the new Bolgheri label) Tuscany has five sub-categories of IGT wines today.
