A cask of bourbon is a barrel that has been used to age bourbon whiskey. Bourbon is a type of American whiskey that is made from at least 51% corn and is aged in new, charred oak barrels. The aging process gives bourbon its characteristic flavor and color. Casks of bourbon are typically made from American white oak, which is known for its tight grain and ability to impart a rich flavor to the whiskey. The barrels are charred on the inside, which creates a layer of caramelized wood that helps to further develop the bourbon’s flavor.
Casks of bourbon are an important part of the bourbon-making process. The aging process mellows the harsh flavors of the new whiskey and allows it to develop its complex flavor profile. The type of wood used for the barrel and the length of time that the whiskey is aged can have a significant impact on the final flavor of the bourbon. Casks of bourbon are also used to age other types of whiskey, such as Scotch and Irish whiskey.
