Updated April 2026.
“Single barrel” is marketing English, not a TTB class. One cask is bottled at its own proof. Bourbon still needs mash at least 51% corn, new charred oak, ≥80 proof. Bottled-in-bond is the legal 100-proof class — a different phrase. A 1.5-ounce pour at 46.5% is about 1.16 drinks if that neck prints it. No 2026 ranking or unpublished mash %.
