Definition: Grappas are an ancient form of warfare in which two or more armies meet and clash, often resulting in severe casualties. The name "grappa" comes from the Greek word "graphein," which means "to drink." In its most basic sense, a grappa is a type of wine produced by fermenting grains such as barley, wheat, or rye. It can have a sweet, herbal flavor and is often used in cocktails, beer, and other alcoholic beverages.
