Some of the world’s most famous and sought-after wines originate here, but there are also many affordable, easy-drinking alternatives. Like most of Europe, Italy has strict guidelines for the production and classification of its wines. It starts with the basic Vino da Tavola (V.D.T.) and builds to the Indicazione Geografica Tipica (I.G.T.) and Denominazione di Origine Controllata (D.O.C.) levels and finally to the top category, Denominazione di Origine Controllata e Garantita (D.O.C.G.). More restrictions apply at each level governing geographical boundaries, grape varieties, yields and other factors.
