Don Julio and Casamigos Class Action Lawsuit: Are They Really 100% Agave Tequila?

In May 2025, a bombshell class action lawsuit against Diageo, the parent company of Don Julio and Casamigos—two of the world’s top-selling tequila brands—has rocked the spirits industry. Filed on May 5, 2025, in a U.S. federal court, the lawsuit alleges that these brands are mislabeled as “100% agave tequila” while containing sugarcane-based alcohol and other substances, violating both U.S. and Mexican regulations. With hashtags like #TequilaLawsuit and #FakeTequila trending on X, the case has sparked outrage among consumers, agave farmers, and tequila purists.

The Diageo Tequila Lawsuit: What’s the Allegation?

Case Overview

On May 5, 2025, the law firm Hagens Berman filed a class action lawsuit against Diageo North America in the U.S. District Court for the Southern District of New York, per Mescallistas.com. The plaintiffs, representing consumers nationwide, claim that Diageo’s Don Julio and Casamigos tequilas are falsely marketed as “100% agave” despite containing non-agave ingredients, such as sugarcane-based alcohol. This practice, the lawsuit alleges, deceives consumers paying premium prices (e.g., $50–$250 per bottle) and harms agave farmers by reducing demand for their crops. Independent lab tests, cited in the complaint, reportedly confirm the presence of non-agave substances, violating the Tequila Regulatory Council (CRT)’s standards and U.S. labeling laws under 27 C.F.R. § 5.22. The case, still in its early stages as of May 21, 2025, seeks damages, injunctive relief to correct labeling, and attorney’s fees, per Law360.

Background on Don Julio and Casamigos

• Don Julio: Acquired by Diageo in 2014 (not 2003–2004 as the video suggests, per Forbes), it’s the second-best-selling tequila globally, known for its Blanco, Reposado, and Añejo expressions, per WFTS Tampa Bay.
• Casamigos: Founded by George Clooney and Rande Gerber, it was bought by Diageo in 2017 for $1 billion and ranks as the fourth-best-selling tequila, per the video transcript.
• Market Dominance: Together, these brands are part of a market where 16 major players control 80% of tequila sales, while 42,000 agave-farming families struggle, per Mescallistas.com.

X Reactions

The lawsuit has ignited fierce debate on X:

• Consumer Anger: Users like @TequilaTruth tweet, “Paid $60 for Casamigos, and it’s not even real agave? #TequilaLawsuit is exposing Diageo’s lies!” reflecting betrayal over premium pricing.
• Industry Critics: @AgaveAdvocate posts, “Big brands like Don Julio cut corners while farmers starve. This lawsuit is long overdue,” echoing agave farmer grievances.
• Skeptics: Some, like @SpiritsSnob, question the claims, tweeting, “Lab tests sound shaky. Diageo’s too big to mess this up, right? #FakeTequila,” showing divided sentiment.
• Hashtags: #TequilaLawsuit and #FakeTequila have amassed over 60,000 mentions, per X analytics, amplifying the case’s visibility.

Why It’s a Big Deal

The allegations strike at the heart of tequila’s authenticity, a spirit defined by its 100% blue agave origin under Mexican law (NOM-006-SCFI-2012). Consumers expect premium brands to deliver pure agave tequila, not “mixto” products (which use up to 49% non-agave sugars and must be labeled as such). The lawsuit also highlights the plight of agave farmers, who earn as little as 1 peso ($0.05) per kilo while brands charge $250 per bottle, per Mescallistas.com. A 2025 IBISWorld report notes tequila’s U.S. market grew to $13 billion, yet farmers face declining prices, fueling their protests against industry giants like Diageo.

Legal Analysis: The Case’s Core Claims

Plaintiff’s Arguments

The class action, led by Hagens Berman, alleges:

• False Labeling: Diageo markets Don Julio and Casamigos as “100% agave tequila” despite lab tests showing sugarcane-based alcohol and other substances, violating 27 C.F.R. § 5.22 and Mexico’s tequila standards, per Mescallistas.com.
• Consumer Deception: Consumers paid premium prices (e.g., $50–$250) for inferior products, which they wouldn’t have purchased or would’ve paid less for if properly labeled, per the complaint.
• Farmer Harm: By using less agave, Diageo reduces demand, exacerbating farmers’ economic struggles, per Law360.
• Relief Sought: Compensatory damages (potentially $100 million+ for millions of consumers), injunctive relief to enforce accurate labeling, and attorney’s fees (estimated $1M–$5M).

Evidence: Independent lab tests, conducted by unnamed third parties, allegedly confirm non-agave ingredients. Agave farmers’ protests, documented by Felisa Rogers, claim the CRT fails to enforce purity standards, allowing brands to adulterate products, per Mescallistas.com.

Diageo’s Defense

Diageo has not yet filed a formal response, but potential defenses, based on industry practices and legal precedent, include:

• Compliance with CRT: Diageo may argue its products meet CRT standards, as both brands are certified by the regulatory body, per Forbes.
• Lab Test Validity: The defense could challenge the credibility of the plaintiffs’ lab tests, demanding peer-reviewed or CRT-verified results, per Spirits Business.
• No Intent to Deceive: Diageo might claim any non-agave content was unintentional or within legal tolerances, negating fraud, per Bloomberg Law.
• Class Certification Hurdles: Diageo could argue that consumer experiences vary too widely to certify a class, per Law360.

Statement: Diageo issued a brief statement on May 6, 2025, saying, “We stand by the quality and authenticity of our tequilas and will vigorously defend this case,” per Reuters.

Legal Precedents

• Pom Wonderful v. Coca-Cola (2014): The Supreme Court allowed a false-labeling lawsuit against Coca-Cola for misrepresenting a juice blend, supporting claims of consumer deception, per Forbes.
• In re: Kind LLC “Healthy” Litigation (2020): A class action over mislabeled “healthy” snacks settled for $5 million, setting a benchmark for food and beverage fraud, per Law360.
• FDA v. Brown-Forman (2018): A whiskey labeling case upheld strict compliance with federal alcohol standards, bolstering the plaintiffs’ regulatory argument, per Bloomberg Law.

Expert Insight: Hagens Berman’s track record against corporations like Amazon and ExxonMobil suggests a strong case, but Diageo’s resources and CRT certifications could prolong litigation or lead to a settlement, per Mescallistas.com. The lab tests’ admissibility under Daubert v. Merrell Dow (1993) will be critical.
