Whiskey sets will work well with other liquors in practical terms, as most liquors are easily enjoyed in rocks or tumbler glasses, and they can be used in a decanter as it has little effect on the drink itself. However, the aesthetic may be odd. Whiskey is enjoyed in a decanter and crystal glasses in particular because of how its rich, golden color looks within. Vodka, for example, wouldn’t have the same effect as it is clear, though some tequilas or rums may enjoy a decorative appeal similar to that of whiskey.
