Updated August 2026.
These are three Four Roses proofs on the official bourbon page, not a tasting trophy. fourrosesbourbon.com prints Four Roses Bourbon at 80 proof (aged minimum 5 years) and notes a 100-proof core SKU also exists. Small Batch is 90 proof. Single Barrel OBSV is 100 proof. A 1.5-ounce pour is 1.00, 1.13, or 1.25 NIAAA drinks. Single barrel is not bottled-in-bond just because it is 100 proof.
The site’s “Aged 6–7 Years” / “7–9 Years” lines are brand copy, not treated here as TTB age statements. Related: Buffalo Trace vs Four Roses, small batch vs single barrel, bonded bourbon.
Proof ladder, not a ranking
| SKU | Official proof | 1.5 oz drinks |
|---|---|---|
| Four Roses Bourbon | 80 / 40% (100-proof SKU also listed) | 1.00 at 80 |
| Small Batch | 90 / 45% | 1.13 |
| Single Barrel OBSV | 100 / 50% | 1.25 |
| Small Batch Select | 104 / 52% | 1.30 |
A 750 mL 50% bottle is about 21 drinks. Four Single Barrel pours are five drinks. NIAAA binge pattern is a health line, not a target. Pour math: whiskey drinks.
