Grappa, also known as Grappa Wine, is an Italian grape-based spirit of between 80 and 100 proof. It is made from the distillation of pomace (also called marc), i.e., the pieces of grapes (including the stems and seeds) that were pressed for the winemaking process. It was originally made to prevent wastage by using the leftovers at the end of the wine season. It quickly became commercialized and mass-produced and sold to the world.
The flavor of grappa, like wine, depends on the type and quality of the grape used. However, many producers have added fruit syrup to sweeten and soften the mix so that it appeals more to the American market.
Grappa is normally served cold and rarely mixed. Sometimes, usually in Italy, grappa is added to espresso and known as a Caffè Corretto.
