I can't think of Italy without thinking about wine (and pasta of course). I am not a wine connoisseur but I have taken a few of them on tour through the Tuscan wine region. We visited vineyards and tasted 5 of the 11 DOCG wines of Tuscany. DOCG - Denominazione di Origine Controllata e Garantita (Denomination of Controlled and Guaranteed Origin) is put in place to protect wine consumers. There are specific production, territory, and harvesting rules and regulations. DOCG wines offer extremely important guarantees of the highest standard such as the certainty of great quality and truthful origin.
There are currently 78 DOCG wines in all of Italy. WebFoodCulure has the list you can view HERE
Each wine has a certain percentage of a grape variety that has to be in each bottle to be labeled a certain wine. For instance: Chianti Classico has to be made with a minimum of 80% Sangiovese grapes. But Chianti has to be made with a minimum of 70% Sangiovese AND 15% cabernet. This is why you see different shades of vines in the fall. There are many different grape varieties growing in each vineyard.
Here is a rundown of Italy's Wine Regions and what grape/wine varieties are produced in each. We start with the highest-yielding regions and work our way down.
