There is no official “best Casamigos.” The Blanco page prints 40% ABV, 750 ml, unaged. A 1.5-ounce pour is one NIAAA drink. Current US bottles we can document print NOM 1609 — Diageo México Operaciones, Atotonilco El Alto, Jalisco (as of August 2026). Older lots have been reported as NOM 1416 (Productos Finos de Agave). Say both. Do not flip them. 818 is NOM 1607 (historical 1137), not 1609. Clase Azul tequila is NOM 1595.

Proof and NOM, not a score

A 750 mL 40% bottle is about 17 drinks. Four pours are four drinks. Additive-free is not a CRT class. Don Julio 1942 is añejo, not extra añejo — a different brand. Pour math: tequila drinks.
