Amarone - or more formally Amarone della Valpolicella - is a powerful red wine from Italy's Veneto region. It is made from the same grapes as Valpolicella: with Corvina and Rondinella as the principal varieties, with other grapes such as Molinara, Corvinone and Dindarella also being used. Amarone is one of the world's most distinctive red wines because of its production method. It is made using the appassimento process, a technique in which the grapes are not fermented until after they are naturally dried in special rooms for three to four months. This air-drying cause the grapes to shrivel, as they lose about 30% of their water. This intensifies the grapes, with the resulting wines being high in alcohol, at least 15% and sometimes as much as 16%.
