Costco hit with class action lawsuit alleging Kirkland tequila isn’t 100% agave

Costco tequila class action overview:

• Who: Plaintiff Ariel Glazer filed a class action lawsuit against Costco Wholesale Corp.
• Why: Glazer claims Costco falsely advertises its Kirkland Signature brand tequila as being made from 100% blue agave.
• Where: The class action lawsuit was filed in Florida federal court.

A new class action lawsuit alleges Costco falsely advertises its Kirkland Signature brand tequila as being made from 100% blue agave.

Plaintiff Ariel Glazer claims the Kirkland Signature tequila is not actually 100% blue agave, despite being advertised as such, and that it contains ethanol from other sources.

Glazer wants to represent a nationwide class of consumers who purchased Kirkland Signature tequila during the applicable statute of limitations period.

“Plaintiff and others similarly situated paid premium prices for the Products in reliance on Defendant’s representations that the Products were created from 100% Blue Weber agave,” the Kirkland tequila class action says.

Kirkland tequila violates U.S., Mexican regulations, class action alleges

Glazer argues Costco’s alleged misrepresentation of the Kirkland Signature tequila’s composition violates both U.S. and Mexican regulations, which require tequila labeled as 100% agave to be made exclusively from blue agave sugars.

Glazer claims she and other consumers paid a premium price for the Kirkland Signature tequila under the belief it was a pure, high-quality product.

“If Plaintiff and others similarly situated had known the truth of the ingredients in the Products, they would not have purchased the Products or would have paid less for them,” the Kirkland tequila class action says.

Glazer claims Costco is guilty of negligence, negligent misrepresentation, unjust enrichment and violating Florida’s Deceptive and Unfair Trade Practices Act.

The plaintiff demands a jury trial and requests declaratory and injunctive relief and an award of compensatory damages for herself and all class members.

In another Costco/Kirkland lawsuit, a California federal judge denied Costco’s motion to dismiss a class action lawsuit alleging its Kirkland Signature Baby Wipes contain toxic per- and polyfluoroalkyl substances (PFAS) despite being marketed as “natural.”
