Both wine and beer are essentially the products of the fermentation process - the fermented broth serves as the basis of the product. Other alcoholic beverages (whisky, rum, brandy) fall under the category of distilled spirits. Distillation is the process by which the alcohol is removed from the fermented broth (or wort) by heating the wort until the alcohol vaporizes, after which it is condensed. When almost pure alcohol is distilled from fermentation, the product is called as grain neutral spirits (GNS).
