Updated March 2026.
Buffalo Trace flagship and Eagle Rare Aged 10 Years are both 90 proof / 45% ABV Mash Bill #1 Kentucky straight bourbons from Buffalo Trace Distillery (Sazerac, Frankfort). A 1.5-ounce pour of either is 1.13 NIAAA standard drinks. They are not the same SKU. Eagle Rare 10 prints a 10-year age statement; the flagship is NAS. “Better” is not a TTB class.
The 17-year Antique Collection bottle is a different proof — a 2025 house letter printed 101. Export 80-proof Buffalo Trace exists. Read the neck. Related: Buffalo Trace, Eagle Rare, Blanton’s.
Same mash bill, different label

A 750 mL at 45% is about 19 standard drinks. Four 90-proof pours are about 4.5 drinks. NIAAA binge pattern is a health line, not a target. No 2026 MSRP; allocation street prices move. Pour math: whiskey drinks.
