Barolos tend to be rich, deeply concentrated full bodied wines with pronounced tannins and acidity. The wines are almost always lightly colored varying from ruby to garnet in their youth to more brick and orange hues as they age. Like Pinot noir, Barolos are never opaque. Barolos have the potential for a wide range of complex and exotic aromas with tar and roses being common notes. Other aromas associated with Barolos include camphor, chocolate, dried fruit, damsons, eucalyptus, leather, licorice, mint, mulberries, plum, spice, strawberries, tobacco, white truffles as well as dried and fresh herbs. The tannins of the wine add texture and serve to balance Barolo's moderate to high alcohol levels (Minimum 13% but most often above 15% ABV). Excessive extraction from prolonged maceration periods and oak aging can give the wines an over-extracted bitterness.
