No. Flagship Buffalo Trace bourbon is Mash Bill #1 on the brand page — rye as the flavoring grain, not wheat. Wheated mash is printed on the W.L. Weller pages from the same Frankfort distillery. Both flagship Buffalo Trace and Weller Special Reserve are 90 proof (45% ABV), so a 1.5-ounce pour of either is 1.13 NIAAA drinks. Same proof is not the same mash story.
Percentages are unpublished. Related: Buffalo Trace, Weller Special Reserve, wheated bourbon, Weller vs Buffalo Trace.
Two 90-proof lines on one campus
| Bottle | Mash language | Proof |
|---|---|---|
| Buffalo Trace | Mash Bill #1 | 90 / 45% |
| Eagle Rare 10 | Mash Bill #1 (brand) | 90 / 45% |
| Weller Special Reserve | Wheated Mash | 90 / 45% |
| Blanton’s Original | Mash Bill #2 | 93 / 46.5% |
A 750 mL 45% bottle is about 19 drinks. Four pours are about 4.5 drinks. NIAAA binge pattern is a health line, not a target. Pour math: whiskey drinks.
