Updated March 2026.
There is no official “best Kentucky bourbon.” Bourbon is a US type.143 — mash ≥51% corn, U.S. distill, new charred oak, ≥40% ABV. “Kentucky” on a straight-bourbon label is a geographic claim, not a tasting score. A 1.5-ounce pour is one NIAAA drink at 40% and 1.13 at 45%. Buffalo Trace, Heaven Hill, Four Roses, Beam, and Brown-Forman are widely distributed Kentucky houses — examples, not a ranking. We will not invent a 2026 MSRP.
