The Cortese white wine grape varietal has been grown in and around south Piedmont, Italy, for at least five hundred years. Its delicate nature and moderate acidity have made it a favorite with people around the world, and it is most commonly served alongside the excellent seafood and shellfish dishes of the part of Italy it is traditionally grown in. Cortese grapes are easily identifiable by their lime and greengage flavors, and their generally delicate and medium bodied character. Cortese wines are also notable for their freshness and crispness, again, making them an ideal match for seafood. Whilst colder years often produce harsher, more acidic Cortese wines, practices such as allowing malolactic fermentation can solve any such problems and still produce delicious white wines made from this varietal. Situated in the north-western part of Italy, the region of Piedmont is known worldwide and is highly respected for the quality of the wines produced there. Many of the most successful sub-regions in Piedmont produce many of the world's finest red wines, such as those made from the excellent Nebbiolo grape varietal in areas such as Barolo and Barbaresco. However, the historic wineries which typify this region use a relatively wide variety of grapes, including Dolcetto and Barbera for their red wines, which are typically aged and have a delightful velvety character. Piedmont isn't all about beautifully complex red wines, though, as it is also famed for high quality, elegant sparkling wines, notably the Asti wines made with the white Moscato grape. The region benefits from a range of terroirs which are often well expressed in the sparkling wines, and a wonderfully consistent climate ideal for vineyard cultivation.
