Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, which are typically made of charred white oak. Uncharred white oak casks previously used for the aging of sherry are also sometimes used. Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels. Rum. Rum, a distilled drink made from fermented sugarcane or molasses, has a typical alcohol concentration of 40% ABV. Some rum is “overproof,” meaning that it has alcohol concentration of at least 57.5% ABV. Most overproof rum exceeds this minimum, usually reaching 75.5% ABV, which is equivalent to 151 proof.
