Updated August 2026.
“Sipping bourbon” is not a TTB class. The liquid is still bourbon under mash ≥51% corn, new charred oak, bottled at ≥80 proof. Straight means ≥2 years and no added flavoring. A 1.5-ounce 40% pour is one NIAAA standard drink; at 50% bottled-in-bond it is 1.25; barrel proof is batch math. This is not a 2022 top-15 tasting and not a 2026 MSRP list.
Age statements, if printed, are the youngest whiskey. NAS can still be old. Related: aged bourbon, bottled-in-bond, barrel proof, should whiskey be chilled.
What people mean by “sipping”
| Reading tool | What it changes | 1.5 oz drinks |
|---|---|---|
| 80–90 proof straight | Legal bourbon; easier grocery pour | 1.00–1.13 |
| Bottled-in-bond | 100 proof; ≥4 years; one season | 1.25 |
| Age statement | Youngest whiskey | Use labeled proof |
| Barrel proof | Batch ABV | Do the math |
A 750 mL 45% bottle is about 19 drinks. Four 90-proof neat pours are about 4.5 drinks. NIAAA binge pattern is a health line, not a target. Ice dilutes proof; it does not change what was poured. Hours to buy the bottle are state law. Pour math: whiskey drinks.
