Updated March 2026.
Single barrel is a bottling story, not a TTB grade. One barrel is dumped and bottled; proof and age are whatever that cask produced. Bourbon still has to meet and the 80-proof floor. Bottled-in-bond is the actual legal class (100 proof, one season, ≥4 years). A 1.5-ounce 40% pour is one NIAAA drink; many single barrels sit higher. This is not a 2022 top-15 tasting.
Blanton’s is the famous single-barrel Age International / Buffalo Trace-campus label — not the only one. Related: Blanton’s, who makes Blanton’s, bottled-in-bond, barrel proof.
Single barrel vs the words next to it
| Term | What it means | Drink math |
|---|---|---|
| Single barrel | One cask; not a TTB class | Read that neck |
| Small batch | Also not TTB; house definition | Use labeled proof |
| Bottled-in-bond | 100 proof; one distillery/season; ≥4 years | 1.25 / 1.5 oz |
| Barrel proof | Bottled at cask strength | Do the math |
A 750 mL at 46.5% (a common single-barrel neighborhood) is about 19.7 drinks — confirm the label. Four 93-proof pours are about 4.65 drinks. NIAAA binge pattern is a health line, not a target. Allocation stickers are not MSRP. Pour math: whiskey drinks.
