The term 'Aging Barrel' can be summarized as a CASK, which is a large barrel used for the aging of alcoholic beverages such as wine and whiskey. The CASK is usually made of wood, and its size and shape can vary depending on the type of beverage being aged. The CASK is filled with the beverage and then sealed, allowing the beverage to age over time. The aging process can take anywhere from several months to several years, depending on the type of beverage and the desired flavor profile.
