“Good bourbon” is not a TTB class. Bourbon is ≥51% corn, US, charred new oak, bottled at 80 proof or more. Straight adds two years. Maker’s Mark prints Proof 90. Knob Creek 9 Year prints Proof 100 — not bottled-in-bond. A 1.5-ounce pour at 45% is 1.13 NIAAA drinks. Weller is allocated — no street price.
