what's the difference between whiskey and bourbon

Whiskey is the broad category; bourbon is one specific style of American whiskey with very strict rules about how it’s made and aged.

Quick Scoop

  • All bourbon is whiskey, but not all whiskey is bourbon.
  • Whiskey can be made anywhere in the world from various grains and barrel types.
  • Bourbon must be mostly corn, made in the U.S., and aged in new charred oak barrels with no added flavors or colors.

What whiskey is (big umbrella)

Whiskey is a broad family of distilled spirits made from fermented grain and aged in wood barrels. Different regions (Ireland, Scotland, the U.S., Japan, Canada) have their own rules and styles.

Common grains and styles include:

  • Barley: Scotch, many Irish whiskeys
  • Rye: American rye whiskey, some Canadian whisky
  • Corn: American whiskeys including bourbon
  • Mixed grains: Many blends and world whiskies

Barrel rules are flexible for “whiskey” in general: it can be aged in used barrels, and sometimes different woods like sherry, port, or rum casks are used to layer flavors.

What bourbon is (specific type of whiskey)

Bourbon is a legally defined American style of whiskey with tight regulations.

Key legal requirements (U.S. standards):

  1. Ingredients (mash bill)
    • At least 51% corn.
    • The rest is usually rye, wheat, and/or malted barley.
  2. Aging
    • Aged in new, charred oak barrels (often American white oak).
    • No flavorings, colorings, or additives allowed—only water to dilute proof.
  3. Strength rules
    • Distilled to no more than 80% ABV (160 proof).
    • Put into the barrel at no more than 62.5% ABV (125 proof).
    • Bottled at at least 40% ABV (80 proof).
  4. “Straight bourbon”
    • Aged at least 2 years in new charred oak.

The heavy corn content plus fresh charred oak gives bourbon its typical sweet, vanilla, caramel, and oak-forward profile.

How this plays out in the glass

If you pour a classic bourbon next to, say, a Scotch or Irish whiskey, you’ll usually notice:

  • Bourbon
    • Sweeter, fuller body
    • Vanilla, caramel, toffee, toasted oak
    • Often feels rich and bold
  • Other whiskeys (examples)
    • Irish: lighter, smoother, more cereal and honey notes
    • Scotch: can be malty, fruity, or very smoky/peaty depending on region
    • Rye: spicier, with peppery or baking-spice character

Think of bourbon as the “sweet talker” of the whiskey world, while the broader whiskey category spans everything from gentle and floral to intensely smoky.

One-line memory trick

Bourbon is a sweet, corn-heavy American whiskey aged in new charred oak; “whiskey” is the giant family it belongs to, covering many grains, countries, and flavor styles.
