Aperitivo is a style of bitter liqueur that is relatively low in alcohol (16% by volume), moderately bitter, and moderately sweet. Bordigas artisanal version is made entirely in their distillery, with no purchased infusions.

The predominant flavors of Bordigas Aperitivo are aromatic herbs, citrus (mostly bitter orange peel) and rhubarb (Chinese rhubarb root). It is used in a number of classic Italian aperitifs, such as the Spritz (three parts Prosecco, two parts Aperitivo, one part soda water, over ice) or by itself with a splash of soda water.
