What distinguishes Amarone della Valpolicella from other Italian red wines?

Amarone della Valpolicella is a wine produced in Veneto region by a peculiar process called appassimento in which the grapes leftover after harvest are dried before the fermentation. This is a method that saturates the grape sugars and flavors, giving the wine a deep aroma, full-bodied dried fruit-flavored taste, and a velvety texture that it is not delivered by any other Italian red wines.
