Updated March 2026.
Kirkland Signature tequila is a Costco contract line, not a named hacienda brand. Current bottles are widely reported as NOM 1173 (Corporativo Destilería Santa Lucía). Older lots printed 1142 or 1472 — the four digits on the bottle in your hand are primary. US warehouse listings commonly show 40% ABV / 80 proof, so a 1.5-ounce pour is one NIAAA drink. 100% agave when so labeled. We will not invent a 2026 warehouse price.
Blanco, reposado, and añejo are CRT age classes, not extra proof. This is not Casamigos (current NOM 1609; historical 1416). Related: who makes Kirkland tequila, Kirkland vs Patrón, tequila types.
What the warehouse bottle actually is
| Check | Conservative line |
|---|---|
| Reported current NOM | 1173 Santa Lucía (VinePair / CRT brand row) |
| Older lots | 1142 / 1472 have been logged. Read this bottle |
| Typical US ABV | 40% / 80. Confirm the neck |
| 1.5 oz drinks | 1.00 at 40% |
| Class | 100% agave when so labeled. Mixto would have to say tequila without 100% |
A 1.75 L 40% handle is about 39.5 standard drinks. Four Blanco pours are four drinks. NIAAA binge pattern is a health line, not a target. Hours to buy it are state law. Pour math: tequila drinks.
