From Luigi Bormioli, the Aero Collection Italian Premium Red Wine Glasses feature: The Aero goblet red wine glasses were designed with a swirling feature called the helical incision that is made to the inside of the bowl.  Due to this feature, as the wine is swirled in the red wine glass, the turbulence created results in a greater air-wine mixture which helps to enhance the wine's aroma and flavor.
