Bourbon is America's native whiskey — by law, made in the U.S. from at least 51% corn and aged in new charred oak. This is the gateway to the bourbon in the vault: the Buffalo Trace, Heaven Hill and Wild Turkey houses, wheated names like Weller and Pappy Van Winkle, single barrels and barrel-proof releases, the annual Antique Collection, and vintage "dusty" bottles. Use this page to find the style or house you're after, then follow the link to its collection.
- At least 51% corn in the mash — the rest usually rye or wheat, plus malted barley.
- Distilled to no more than 160 proof (80% ABV), so it keeps its grain character.
- Aged in new, charred oak barrels, entered at no more than 125 proof.
- Bottled at no less than 80 proof (40% ABV); nothing added but water — no coloring, no flavoring.
- Made anywhere in the United States — only Kentucky-made bourbon may say "Kentucky Straight Bourbon."
- "Straight" means aged at least two years; "bottled-in-bond" means one distillery and one season, at least four years, bottled at 100 proof.
Every bourbon is at least 51% corn, but the secondary grain sets the style. Most Kentucky bourbons are rye-recipe, where rye brings pepper and spice; high-rye versions push that further. Wheated bourbons swap the rye for wheat, which tends to read softer and rounder — the recipe behind Buffalo Trace's Weller and Pappy Van Winkle. Corn gives the sweetness, malted barley drives fermentation, and the new charred oak supplies the color, vanilla and caramel.
A few terms tell you most of what you need. Single barrel means every bottle comes from one cask, so it varies slightly; small batch is a marriage of a limited number of barrels. Barrel or cask proof is bottled uncut, straight from the barrel. Bottled-in-bond is a federal guarantee: one distillery, one season, four years, 100 proof. An age statement is the youngest whiskey in the bottle; "NAS" means none is stated.

Collector Note
Bourbon collecting spans a wide range. At one end are everyday-priced benchmarks; at the other, allocated and limited releases — the Antique Collection, wheated Weller and Pappy, single barrels and barrel-proof batches — that are hard to find at retail and trade well above release. Vintage "dusty" bottles add another dimension, prized for whiskey distilled at closed or changed distilleries. Across all of it, the specific release, proof and bottle condition determine value.
What Counts as Bourbon
Bourbon's definition is set by U.S. federal regulation (the Standards of Identity, 27 CFR). A bourbon must be made in the United States from a mash of at least 51% corn, distilled to no more than 160 proof, aged in new charred oak barrels entered at no more than 125 proof, and bottled at a minimum of 80 proof, with no added coloring or flavoring. There is no minimum aging period for bourbon itself. "Straight bourbon" must be aged at least two years (with an age statement if it is under four). "Bottled-in-bond," under the 1897 act, must be the product of one distillery and one distilling season, aged at least four years in a federally bonded warehouse, and bottled at 100 proof. Bourbon may be made in any state, but only bourbon produced in Kentucky may carry "Kentucky Straight Bourbon"; in 1964 the U.S. Congress recognized bourbon as a distinctive product of the United States.

Frequently Asked Questions
What makes a whiskey a bourbon?
To be labeled bourbon, a whiskey must be made in the United States from a mash of at least 51% corn, distilled to no more than 160 proof, aged in new charred oak barrels (entered at no more than 125 proof), and bottled at no less than 80 proof — with nothing added but water. There is no minimum age for bourbon itself; "straight bourbon" must be aged at least two years, and "bottled-in-bond" must come from one distillery and one distilling season, age at least four years, and be bottled at 100 proof.
What's the difference between wheated, high-rye and traditional bourbon?
All bourbon is at least 51% corn; the difference is the secondary "flavoring" grain. Traditional bourbons use rye, which brings pepper and spice; high-rye bourbons lean further into it; wheated bourbons replace the rye with wheat, which tends to read softer and rounder. Buffalo Trace's Weller and Pappy Van Winkle are wheated, while most Kentucky bourbons are rye-recipe. Bourbon can be made anywhere in the U.S., but only bourbon made in Kentucky may be labeled "Kentucky Straight Bourbon."
