The Famous Grouse launches the Cask Series, a new range of blended whiskies inspired by the impact that different types of oak casks have on flavor development. This series is designed to show how different types of casks can influence the character of the whisky and deliver a variety of delicious flavors. The variants of the cask series maintain the reliable smooth taste, quality, and character of Scotland's most beloved whisky, but with a delightful new twist. The predominance of American oak, including first-fill bourbon casks, imparts delicious caramel and vanilla notes to the Bourbon Cask blend.
