High Quality Content by WIKIPEDIA articles! Barbera is a red Italian wine grape variety that, as of 2000, was the third most-planted red grape variety in Italy (after Sangiovese and Montepulciano). It produces good yields and is known for deep color, low tannins and high levels of acid (which is unusual for a warm climate red grape). Century-old vines still exist in many regional vineyards and allow for the production of long-aging, robust red wines with intense fruit and enhanced tannic content. The best known appellation is the DOCG (Denominazione di Origine Controllata e Garantita) Barbera d`Asti in the Piedmont region. When young, the wines offer a very intense aroma of fresh red and blackberries. In the lightest versions notes of cherries, raspberries and blueberries and with notes of blackberry and black cherries in wines made of more ripe grapes. Many producers employ the use of toasted (seared over a fire) oak barrels, which provides for increased complexity, aging potential, and hints of vanilla notes. The lightest versions are generally known for flavors and aromas of fresh fruit and dried fruits, and are not recommended for cellaring. Wines with better balance between acid and fruit, often with the addition of oak and having a high alcohol content are more capable of cellaring; these wines often result from reduced yield viticultural methods.
