A bourbon label mixes two kinds of words: terms the federal rules define, and terms the marketing department picked because they sound good. Knowing which is which saves money, especially on a gift bottle.
The words that are promises
- Bourbon. Made in the US from at least 51% corn, aged in new charred oak containers, with nothing added but water. The full rules are in How to Host a Bourbon Tasting.
- Straight. Aged at least two years, with no coloring or flavoring. If it is under four years old, the label has to state its age.
- Bottled in Bond. One distillery, one distilling season, at least four years in a federally bonded warehouse, bottled at exactly 100 proof. It is the strictest phrase on the shelf, and bonded bottles are often great values.
- An age statement. "8 Years" means the youngest whiskey in the bottle is at least eight years old, not the average.
- A state name. "Kentucky Straight Bourbon" tells you where it was distilled. Bourbon itself can legally be made anywhere in the US.
The words that describe, loosely
- Single barrel. Every bottle comes from one barrel, and many list the barrel number. It is honest in practice, and it means two bottles of the same brand can taste noticeably different.
- Barrel proof / cask strength. Bottled at or near barrel strength, with no water added. Expect 110 proof or more, and plan to add a few drops of water yourself, as covered in Should You Add Water to Whisky?.
- Wheated / high rye. Real descriptions of the grain recipe, with no legal threshold. Our mash bill guide explains what each does to the taste.
The words that mean nothing in particular
- Small batch. No legal definition. Small is whatever the brand says it is.
- Reserve, Select, Special, Private Stock. Marketing.
- Handcrafted, artisanal, craft. Marketing. Huge distilleries use these words too.
- Sour mash. A real process, where spent mash from the last batch starts the next one, like sourdough starter. But nearly every major bourbon is made this way, so seeing it on a label tells you almost nothing.
Who actually made it
Look at the fine print near the bottom. "Distilled by" names the distillery that made the whiskey. "Bottled by" or "Produced by" does not promise that. Plenty of brands buy whiskey from larger distilleries and bottle it under their own name. Much of it is excellent. Just don't pay extra for a backstory.
Put it to the test
The best way to learn which words matter is to taste a bonded bottle, a single barrel and a small batch side by side. Our Bourbon 101 kit prints a one-page label decoder with all of these terms, plus a four-bottle flight in three price tiers and a blind tasting game. It's for adults 21+.
