What does whisky mean?

Whisky is a spirit distilled from fermented grain mash and aged in wooden barrels. The grain can be barley, corn, rye or wheat, and each country sets its own rules for what can carry the name.

That is why whisky is best understood as a family. Scotch, Irish whiskey, Japanese whisky, Canadian whisky, rye and bourbon are all members. Each has its own grain choices, aging rules and typical flavors, but they share the same basic process of mashing, fermenting, distilling and maturing.

What does bourbon mean?

Bourbon is a type of American whiskey defined by US law. To be called bourbon, the spirit must meet a specific set of rules.

The grain mix must be at least 51% corn. The spirit must be aged in new charred oak containers. It must be distilled to no more than 160 proof, enter the barrel at no more than 125 proof, and be bottled at no less than 80 proof. Nothing can be added except water, so no coloring or flavoring.

There is no minimum aging period for plain bourbon. To use the label “straight bourbon,” the whiskey must age at least two years. The corn and the fresh charred barrels are why bourbon often tastes of caramel, vanilla and toasted oak.

Bourbon vs whisky: what actually sets them apart?

The key difference is category versus type: bourbon is one specific kind of whisky with strict legal requirements. When people compare bourbon vs whisky, they usually mean bourbon against other styles, most often Scotch.

Scotch is made in Scotland and aged at least three years in oak. It is often made from malted barley, and some bottles use peat smoke during drying, which gives a smoky character. Bourbon leans sweeter and rounder because of its corn-heavy mash and brand-new barrels.

Rye whiskey is another close relative. It uses at least 51% rye, which tends to taste spicier and drier. Same family, different recipe.

Does bourbon have to come from Kentucky?

No. Bourbon can be made anywhere in the United States, although the large majority of it comes from Kentucky. The name is commonly linked to Bourbon County in that state, though the exact origin is debated.

Tennessee whiskey is a close cousin. It is typically made in a similar way to bourbon, with an extra charcoal-filtering step before aging.

Whisky or whiskey: which spelling is right?

Both are right, and the choice mostly depends on where the spirit comes from. Scotland, Canada and Japan usually write whisky. The United States and Ireland usually write whiskey.

There are exceptions. Some American producers, such as Maker’s Mark, use “whisky” on their labels. In general writing, pick one spelling and stay consistent. When you are naming a specific style, follow the spelling that region uses.

How can you remember which one to use?

Remember that bourbon is the specific type and whisky is the general group. These tricks help.

• Squares and rectangles: All squares are rectangles, but not all rectangles are squares. All bourbon is whisky, but not all whisky is bourbon.
• The “e” trick: Countries with an “e” (Ireland, United States) write whiskey. Countries without one (Scotland, Canada, Japan) write whisky.
• Corn plus new barrels: If a label mentions at least 51% corn and new charred oak, you are reading about bourbon.
