After it is used to mature other whiskeys, it can release various sweet flavors such as vanilla, cream, coconut, almond, etc., as well as delicate Floral and fruity. Generally speaking, in terms of color, body and taste, whiskey aged in bourbon barrels is not as rich as that aged in sherry barrels. Whiskey matured in bourbon barrels will show a lighter golden yellow color Softer and more delicate. In addition to directly using bourbon barrels, the Scotch whiskey industry also uses some oak barrels that have been reprocessed on the basis of bourbon barrels, such as Hogshead and Gorda barrels.
