There is no official “best Costco tequila.” The warehouse mixes Kirkland private-label lots with national SKUs. Typical US cores are 40% ABV — one NIAAA drink per 1.5 ounces, read the neck. Current documented Kirkland tequila production is NOM 1173; older lots have been reported as 1142 and 1472. Say both. Casamigos current NOM is 1609 (historical 1416). 818 is 1607. Clase Azul tequila is 1595.

NOM first, sticker second
| Keep | |
|---|---|
| Typical US ABV | 40% — confirm the neck |
| Kirkland current NOM | 1173 CRT/trade |
| Kirkland historical | 1142 / 1472 leftover lots |
| Casamigos | 1609 current / 1416 historical |
A 750 mL 40% bottle is about 17 drinks; a 1.75 L is about 39. Additive-free is not a CRT class. Pour math: tequila drinks.
