Whiskey vs. Rum — What's the Difference?

Whiskey is made primarily from various grains, including barley, corn, rye, and wheat, which are fermented, distilled, and aged in wooden barrels, often oak, which impart a distinct flavor profile that includes notes of vanilla, spice, and smoke. On the other hand, rum is distilled from sugarcane byproducts like molasses or sugarcane juice, and its aging process, often in former whiskey or bourbon barrels, enhances its naturally sweet flavor, characterized by notes of caramel, molasses, and tropical fruit.

In terms of production, whiskey's aging process is crucial for developing its depth and complexity of flavors; it must be aged for several years under specific conditions to be classified as whiskey, especially in regions like Scotland and the U.S. Whereas rum can be aged for varying lengths of time, and while aging can enhance its flavor, some rums are also sold unaged, offering a lighter taste.

Geographically, whiskey is most famously associated with countries like Scotland, Ireland, the United States, and Canada, each producing distinctive styles such as Scotch, Irish whiskey, bourbon, and rye. Rum, however, is closely tied to the Caribbean and Latin America, with each region contributing unique variations based on local traditions and production techniques.

Culturally, whiskey has a broad appeal and is often enjoyed in cocktails like the Old Fashioned or neat to appreciate its complex flavor profile. Rum’s versatility makes it popular in a wide range of cocktails from the light and refreshing Mojito to the rich and complex Mai Tai, appealing to a diverse palate.
