Bourbon Basics: How It Differs From Other Whiskey Types

black labeled bottle

Bourbon holds a special reputation within the whiskey world, and many beginners want to know what sets it apart from other styles. The first rule to remember is simple: all bourbon is whiskey, but not all whiskey is bourbon. In this guide, we’ll break down the history, production rules, and flavor differences, and share product picks and cocktail uses to help you appreciate bourbon’s unique place in the whiskey family.

The History of Bourbon

Bourbon’s roots trace back to 18th-century Kentucky settlers, who relied on corn as their primary grain. Over time, production methods evolved into today’s standards, and in 1964, the U.S. Congress declared bourbon “America’s Native Spirit.” Culturally, bourbon holds a similar prestige in the U.S. as Scotch whisky does in Europe, tied to heritage and craftsmanship.

What Is Whiskey?

Whiskey is a distilled spirit made from fermented grain mash and aged in wooden casks. Depending on the grains, distillation style, and region, you get many types: Scotch, Irish, rye, Japanese, and American whiskeys. Each follows different rules and traditions. (Want to dive deeper?

Production Methods and Flavor Notes

Bourbon stands out because it must be made in the United States (though traditionally from Kentucky), comprising at least 51% corn. It generally ages in new charred oak barrels and contains no added flavors or coloring. The result? A sweet, full-bodied experience with notes of caramel and vanilla. Beginners may enjoy lower-proof bourbons with a softer profile, while enthusiasts can explore single barrel or cask strength releases for more intensity.

What Makes Bourbon Unique?

To legally be called bourbon, whiskey must:

  • Be made in the United States

  • Use a mash bill with at least 51% corn

  • Age in new charred oak barrels

  • Contain no added flavors or coloring

  • Be distilled to no more than 160 proof and barreled at no more than 125 proof

Note: In the U.S., proof is simply double the alcohol by volume (ABV). For example, a whiskey that is 100 proof is 50% ABV.

These rules create bourbon’s sweet, full-bodied profile with notes of caramel, vanilla, and oak. Some distillers use the sour mash method, reusing a portion of spent mash to keep consistency in flavor.

Bourbon vs Other Whiskeys

Bourbon is a subset of whiskey, but its production rules set it apart:

  • Scotch is made from malted barley in Scotland, often smoky, and aged in used casks.

  • Irish whiskey is usually triple-distilled, lighter, and smoother.

  • Rye whiskey (at least 51% rye grain) is spicier and drier.

  • Bourbon is sweeter and fuller, thanks to its corn base and new oak barrels.

Expert Notes

Booker Noe of Jim Beam once described bourbon as a “sippin’ whiskey,” reflecting its balance of tradition and enjoyment. Distilleries emphasize their craft, from grain selection to barrel aging, reinforcing bourbon’s reputation as a spirit rooted in heritage.
