These are two Beam Suntory Kentucky straight bourbons at different proofs. The Jim Beam page prints Proof: 80. Knob Creek’s site prints the 9 Year Old bourbon at Proof 100. A 1.5-ounce pour is one NIAAA drink at 40% and 1.25 drinks at 50%. This is not a 2022 winner and not a 2026 MSRP list.
100 proof is not bottled-in-bond by itself. Related: Basil Hayden vs Knob Creek, Beam proof, bonded bourbon.
