Bourbon is a specific type of whiskey with stricter rules; all bourbon is whiskey, but not all whiskey is bourbon. The key differences are in ingredients, where it’s made, aging rules, and flavor.

Quick Scoop

What is whiskey?

Whiskey is a broad family of distilled spirits made from fermented grain mash (corn, barley, rye, wheat) and aged in wooden barrels, usually oak.

  • It can be made in many countries: the U.S., Scotland, Ireland, Japan, Canada, and more.
  • Different styles (Scotch, Irish whiskey, Japanese whisky, Canadian whisky, American whiskey) have their own local rules and flavor profiles.
  • Barrels are often used and reused (for example, Scotch often ages in ex‑bourbon or ex‑sherry casks), which adds complex flavors over time.

Think of whiskey as the big umbrella category that covers many regional styles and recipes.

What is bourbon?

Bourbon is a legally defined American whiskey with tighter requirements.

Most regulations boil down to:

  1. Made in the United States.
  1. Mash bill (grain recipe) is at least 51% corn.
  1. Distilled to no more than 160 proof (80% ABV).
  1. Put into the barrel at no more than 125 proof (62.5% ABV).
  1. Aged in new, charred oak barrels (not used barrels).
  1. Bottled at 80 proof (40% ABV) or higher, with no additives except water (no added color or flavor).

Because of the high corn content and new charred oak, bourbon usually tastes sweeter and richer, with lots of vanilla, caramel, and oak notes.

How this plays out in the glass

  • Bourbon
    • Sweet edge from corn, plus big vanilla and caramel from fresh charred oak.
* Often feels round, rich, and approachable even at higher proof.
  • Other whiskeys
    • Scotch may be smoky or “peaty,” especially from regions that burn peat to dry malted barley.
* Irish whiskey tends to be smoother and lighter, often triple‑distilled.

* Rye whiskey is usually spicier and more peppery because of the rye grain.

A simple way to picture it: if whiskey is the whole playlist, bourbon is one very popular, sweet‑leaning track on that playlist.

Common questions people have

  1. “Does bourbon have to be made in Kentucky?”
    • No. It must be made in the U.S., but not necessarily in Kentucky, even though many famous bourbons are from there.
  1. “Is Jack Daniel’s bourbon or whiskey?”
    • Many experts note that Tennessee whiskey meets bourbon rules but adds an extra charcoal‑filtering step, which is why it’s usually labeled as Tennessee whiskey instead of bourbon.
  1. “Is one ‘better’ than the other?”
    • It’s mostly about taste: if you like sweeter and smoother, you’ll often prefer bourbon; if you like smoky, grassy, or very spicy notes, other whiskeys may win.

Tiny story to remember it

Imagine you walk into a bar labeled “Whiskey World.” Inside are rooms for Scotch, Irish, Canadian, Japanese, rye, and one warm room glowing amber and smelling like caramel corn. That room is bourbon: still part of Whiskey World, but with its own house rules—U.S. only, mostly corn, and everything aged in fresh, charred oak so the flavor hits big and sweet.
