Whiskey Stones were designed by a single malt scotch lover named Andrew Hellman. This gentleman wanted the ability to chill his liquid goal without diluting them down. After much research, he came up with the idea of using natural soapstone to chill drinks due to its softness that wouldn’t scratch the glass (or add additional flavors). These stones have the unique ability to retain temperature for extended periods of time, so all you have to do is keep them chilled. Add three to your next drink, let them stand for five minutes and they will keep a perfect sipping temperature of 50 degrees.
A handful of ice will take a drink to just under 40 degrees and will change the overall profile of the liquor. Temperatures in the high 30s are far too cold for good whiskey so keeping the bottle in the freezer or risking storage in the fridge are not an option. The Reasoning: the wood oils in the whiskey, which have leeched into the liquid from the carefully selected cask it was aged in and which carry all the flavor, tend to congeal and “close down” the flavor of the drink itself when the temperature goes below 50.
So as they say – Skip the ice; Serve your drinks on the rocks.
