Many will disagree with the makers of this product as it is completely dependent on how you like your whiskey. If you enjoy having your whisky cold but are left unsatisfied when the ice cubes melt and dilute the taste of your favourite beverage? If so, then these whiskey stones are perfect for you. They are placed in the freezer before use allowing you to keep your drink cold without ruining the taste. These make a great gift for whiskey drinkers.
