While it is looked down upon to add ice to whiskey because it waters down the flavor and ruins the drinking experience, some people like to keep their glasses cool. The solution for a cold drink without sacrificing the signature whiskey flavor is very simple — whiskey stones, which stay cold for long periods of time and don't dilute drinks.

Despite the name, not all whiskey stones are made from stone. Traditionally, they were made with soapstone, but now whiskey stones come in metal varieties, sometimes with a gel center that stays frozen longer than stone varieties.

No matter what your whiskey stones are made from, you should freeze them for four hours before using, wash them after each use, and store them in your freezer so they’re ready to go. For optimal cooling, put your stones in the glass first then slowly pour your drink over the top, and wait two to three minutes before enjoying.
