Costco Kirkland Tequila Adulterated '100% Agave' RICO Class Action (No Settlement Yet)

A class action lawsuit (Salisbury v. Costco Wholesale Corporation, Case No. 2:25-cv-02277) was filed November 14, 2025, in the U.S. District Court for the Western District of Washington. The complaint alleges Costco knowingly sold Kirkland Signature tequila products labeled '100% DE AGAVE' and '100% AGAVE AZUL' that actually contained significant levels of non-agave alcohol. Nuclear magnetic resonance testing reportedly found the Kirkland Blanco contained only 60–80% agave-derived ethanol, while the Reposado contained as little as 5–25% agave-derived ethanol—so low it may not even qualify as tequila under Mexican law. The 54-page complaint includes federal RICO Act claims alleging an 'Adulterated Tequila Enterprise.' The case is brought by Hagens Berman Sobol Shapiro LLP. As of February 2026, Kirkland Signature tequilas are no longer listed on Costco's website. This is a lawsuit, not a settlement; no claims process or payout information exists at this time. This listing may involve a proposed or pending settlement. Final approval, claim availability, eligibility, timing, and any payment depend on court approval, administrator instructions, and final settlement terms. Payout does not administer the settlement, determine eligibility, or guarantee payment.
