While I can’t attest to the sterility of placing freezing Whiskey Stone in your alcoholic beverage, we can assure you that these stones, once cooled, will keep your drink chilled just as long as ice, perhaps even longer. These stones don’t have to deal with the whole melting thing, meaning your drink doesn’t get watered down. More bang for your buck.
Not to mention, saying you’ll have your drink on the rocks was never so literal or fun.
