Updated July 2026.
Buffalo Trace and Four Roses are different companies and different proof ladders. Buffalo Trace prints 90 proof / 45% ABV and Mash Bill #1. Four Roses Yellow Label commonly prints 80 proof / 40% on US bottles; Small Batch is commonly 90; Single Barrel is commonly 100. A 1.5-ounce pour is 1.13 drinks at 45% and 1.00 at 40%. This is not a 2023 winner.
Four Roses talks about two mash bills and five yeasts. Those percentages are not restated here as a 2026 official table. Related: Buffalo Trace, small batch vs single barrel.
Proof ladder, not a score
| Bottle | Typical US proof | 1.5 oz drinks |
|---|---|---|
| Buffalo Trace | 90 / 45% (brand page) | 1.13 |
| Four Roses Yellow Label | 80 / 40% common | 1.00 |
| Four Roses Small Batch | 90 / 45% common | 1.13 |
| Four Roses Single Barrel | 100 / 50% common | 1.25 |
A 750 mL 40% bottle is about 17 drinks; 45% is about 19. Four 90-proof pours are about 4.5 drinks. NIAAA binge pattern is a health line, not a target. Confirm Four Roses necks. Pour math: whiskey drinks.
