There are some things that don't improve with watering down, and whiskey is one of them. A little chill, on the other hand, goes a long way towards helping you enjoy your drink. These whiskey stones are just what you need to introduce the chill without the water. Cut from granite, they become cold and impart that chill to liquids, without melting. Reusable and efficient. Keep these in the freezer so they are ready rock when you need them!
