The Piedmont wine region is located in the northwestern part of Italy and is known for its production of ASTI, a sparkling white wine made from the Moscato grape. ASTI is a DOCG (Denominazione di Origine Controllata e Garantita) wine, meaning it is of the highest quality and has been produced in the same traditional way for centuries. The Piedmont wine region is also home to many other DOCG wines, such as Barolo and Barbaresco.
