For The Famous Grouse Cask Series we use different types of casks to create smooth blends with distinctive character and style. Our Master Blender has selected whisky mostly aged in American oak, including bourbon casks, to create a deliciously smooth blend with a layer of caramel and vanilla sweetness. We call it The Famous Grouse Bourbon Cask. Bottle 23 x 30ml. 30ml = 9.5g alcohol = 275kJ/66kcal. 100ml = 916kJ/221kcal.
