Rum vs. Whiskey: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 30, 2023
Rum is a liquor distilled from sugarcane or molasses, while whiskey is distilled from fermented grain mash, often aged in wooden casks.
Key Differences
Rum and whiskey are both popular spirits consumed worldwide, but they differ significantly in their origins, ingredients, and production processes. Rum, with its tropical roots, is primarily distilled from sugarcane juice or molasses, a byproduct of sugar production. In contrast, whiskey is distilled from fermented grain mash, which can include barley, corn, rye, and wheat, and often hails from regions with cooler climates.
When it comes to the aging process, both rum and whiskey undergo maturation in barrels, which imparts flavor, color, and character to the spirits. However, while rum might be aged in a variety of barrels that have previously held other spirits or wines, whiskey, especially types like bourbon, has specific requirements for the type of barrels used, often mandating the use of new charred oak barrels.
From a regional standpoint, rum is traditionally associated with the Caribbean, but it's produced in other sugarcane-growing regions as well. Whiskey, on the other hand, has strong ties to countries like Scotland, Ireland, the U.S., and Canada, with each region having distinct production methods and regulations that define their unique whiskey varieties.
The flavor profiles of rum and whiskey vary greatly due to their different base ingredients and production methods. Rum generally exhibits sweet, tropical, and fruity notes, often with caramel or molasses undertones. In contrast, whiskey's flavor can range from sweet to smoky, with nuances of vanilla, oak, fruits, and grains, largely influenced by the specific grains used and the aging process.
