For those looking to elevate their Scotch drinking experience, this set of nine Polar Whiskey Stones brings a new twist for anyone who likes their liquor slightly chilled. As opposed to traditional ice cubes Whiskey Stones can chill your drink to the perfect temperature, without diluting the desired liquor and keeping the balance of flavors in check. Typically, a set of 3 cubes will lower the temperature of a 2oz drink by 5C. Anything more and you risk the flavors tightening up. The stones won't scratch your glasses or chip off in your drink. Also there is no worry of breaking your glasses like Granite stones.
