Three federal class action lawsuits filed in 2025 accuse Diageo North America, the parent company of Don Julio and Casamigos, of selling tequila labeled “100% agave” that independent lab tests suggest contained as little as 33% agave-derived alcohol. The first case was filed in New York in May 2025, followed by a second in Florida and a third in California, the last of which also carries RICO charges that could mean triple damages for plaintiffs. The products named include Don Julio Blanco, Don Julio 1942, Casamigos Blanco, and Casamigos Reposado. Diageo denies all allegations and filed motions to dismiss in late 2025. As of June 2026, all three lawsuits remain active, no settlement has been reached, and no trial dates have been set. If you purchased Don Julio or Casamigos tequila in the United States between 2020 and 2025, you may be part of the affected consumer class. No claims portal is open yet. Read the full breakdown below.
If you have ever paid $50, $80, or even $180 for a bottle of Don Julio tequila because the label said “100% de Agave,” you deserve to know the truth. A series of federal class action lawsuits filed in 2025 claim that Diageo North America, the parent company of Don Julio and Casamigos, has been selling adulterated tequila to American consumers while charging premium prices based on a label that may not be accurate.
This article covers everything: the real allegations, the lab test results, which courts are involved, what Diageo says in its defense, which products are named, who qualifies to join the lawsuit, and the latest 2026 update on where these cases stand today. Whether you are a consumer who wants to know if you can sign up, or a legal professional tracking the litigation, this is the most complete breakdown available.
What Is the Don Julio Lawsuit?
The Don Julio lawsuit is a class action legal action filed against Diageo North America, Inc. in federal court. Diageo is one of the largest alcohol companies in the world and owns both the Don Julio tequila brand and Casamigos, the celebrity tequila brand originally created with George Clooney.
The lawsuit was first filed on May 5, 2025 in the U.S. District Court for the Eastern District of New York. Two more class action complaints followed: one filed in Miami-Dade County, Florida on May 15, 2025, and a third filed in San Francisco, California on July 4, 2025. All three cases center on the same core allegation: that Don Julio and Casamigos tequilas are not made from 100% agave as their labels claim.
This is not a minor technicality. Under both U.S. and Mexican law, tequila that is labeled “100% agave” must be produced entirely from Blue Weber agave. If a product contains cane alcohol or any other non-agave spirit source, it cannot legally carry that label. Instead, it should be classified and sold as “mixto” tequila, which is a far cheaper and less prestigious category.

The Don Julio Agave Lawsuit: What the Lab Tests Found
The central allegation in all three class action lawsuits against Don Julio and Casamigos is that independent laboratory testing revealed that the tequilas labeled as “100% agave” actually contain significant amounts of cane alcohol or other non-agave spirit sources. If this is true, the products are legally “mixto” tequilas being sold at 100% agave premium prices.
The California lawsuit is the most detailed because it was the first to include actual lab test results. Here is what the testing reportedly found:
| Product Tested | Agave-Derived Ethanol Found | What 100% Agave Means |
|---|---|---|
| Casamigos Blanco | Approximately 33% | Should be 100% |
| Casamigos Reposado | Approximately 42% | Should be 100% |
| Don Julio Blanco | Approximately 42% | Should be 100% |
| Don Julio 1942 Anejo | Approximately 33% | Should be 100% |
These numbers matter enormously. Even “mixto” tequila, the lowest quality category, must contain at least 51% agave-derived alcohol by law. The lab results in the California lawsuit suggest that some of these products may not even meet that floor threshold, which would make them arguably not tequila at all under either Mexican or American regulatory definitions.
Blue Weber agave is an agricultural crop that takes 5 to 10 years to fully mature before it can be harvested. Because of that long growth cycle and the difficulty of harvesting, agave is expensive. Cane alcohol, by contrast, is cheap and easy to produce industrially. The financial incentive for a company to quietly substitute cane alcohol for agave, while continuing to market and price the product as 100% agave, is substantial.
| Independent Note: The California case was filed as a RICO case, which stands for the Racketeer Influenced and Corrupt Organizations Act. RICO claims are typically used against organized crime but can apply to systematic corporate fraud. A successful RICO class action can result in triple damages for plaintiffs. |
Why Are Don Julio and Casamigos Named Together in the Same Lawsuit?
Both Don Julio and Casamigos are owned by Diageo North America. That shared corporate parent is exactly why they are named together in the same class action lawsuits. Plaintiffs argue that the alleged adulteration was a company-wide practice, not isolated to just one brand.
Don Julio is positioned as a luxury tequila brand. Diageo markets it as a premium product, and prices reflect that: a bottle of Don Julio 1942 can retail for $150 to $200 or more at many liquor stores. Casamigos is marketed as a super-premium tequila and was acquired by Diageo in 2017 for approximately $1 billion, at that time one of the largest deals in spirits history.
The lawsuit argues that consumers paid these elevated prices specifically because of the “100% agave” marketing claim. If that claim was false for both brands under the same corporate roof, the class of potentially affected consumers runs into the millions of people across the United States.
| Brand | Market Positioning | Owner | Price Range |
|---|---|---|---|
| Don Julio Blanco | Premium tequila | Diageo North America | $45 to $65 |
| Don Julio Reposado | Premium aged tequila | Diageo North America | $55 to $75 |
| Don Julio 1942 | Luxury ultra-premium | Diageo North America | $150 to $200+ |
| Don Julio 70 | Premium cristalino | Diageo North America | $90 to $130 |
| Casamigos Blanco | Super-premium tequila | Diageo North America | $50 to $70 |
| Casamigos Reposado | Super-premium aged | Diageo North America | $55 to $75 |
The Three Don Julio Class Action Lawsuits: New York, Florida, and California
The New York Lawsuit (May 2025)
The first class action complaint was filed on May 5, 2025 in the Eastern District of New York by law firm Hagens Berman Sobol Shapiro LLP. The three named plaintiffs are New Jersey resident Avi Pusateri, New York mixology instructor and bartender Chaim Mishulovin who runs the Jazz Age Cocktails Instagram account, and Sushi Tokyo Inc., a Brooklyn restaurant and bar.
The complaint seeks at least $5 million in damages and asks the court to issue an injunction stopping Diageo from continuing the allegedly deceptive marketing practices. It also requests that Diageo correct its labeling and advertising. The New York suit alleges violations of consumer protection laws and false advertising statutes.
The Florida Lawsuit (May 2025)
A second complaint was filed shortly after in Miami-Dade County, Florida. The Florida case closely mirrored the New York complaint in its core allegations, which Diageo later noted in its motion to dismiss, arguing the Florida plaintiff essentially filed a “me too” lawsuit after becoming aware of the New York case.
Both the Florida and New York suits demanded jury trials, meaning if these cases proceed past the dismissal motions, they would ultimately be decided by ordinary American citizens rather than a judge alone.
The California RICO Lawsuit (July 2025)
The California case, filed in San Francisco on July 4, 2025, is the most aggressive of the three. It was filed as a RICO case, meaning plaintiffs are alleging not just consumer fraud but organized and systematic deception. The California lawsuit is also the first of the three to include documented laboratory test results, which gave it an evidentiary weight the earlier complaints lacked.
Under RICO, successful plaintiffs can recover three times their actual damages, which would significantly increase the financial exposure for Diageo if this case succeeds.
Diageo’s Response: What the Company Says
Diageo has denied all allegations across all three lawsuits. When the initial New York complaint was filed in May 2025, the company issued a clear statement: all bottled Casamigos and Don Julio tequilas labeled as “100% agave” are made from 100% Blue Weber agave, and the company is confident in its defense.
In October 2025, Diageo took formal legal action to shut the cases down by filing motions to dismiss. The company filed a motion to dismiss the Florida lawsuit on October 29, 2025 in the U.S. District Court for the Southern District of Florida. It filed a second motion to dismiss in the Eastern District of New York on November 1, 2025.
In its dismissal filings, Diageo argued that the plaintiffs’ allegations were legally “implausible” and lacked proper scientific foundation. The company characterized the laboratory testing behind the claims as incomplete and coming from a single, unidentified European company whose methodology it called unvalidated. Diageo also stated that its tequilas comply fully with Mexico’s official tequila production standard, known as NOM-006, which is the regulatory framework that governs all authentic tequila production.
The company accused the plaintiffs of trying to, in their words, “alchemize rumor into fraud,” referring to the fact that early news coverage of tequila industry concerns in Mexico, including demonstrations by agave farmers protesting the use of non-agave ingredients, was part of what triggered the initial investigation.
| Independent Context: As of June 2026, the courts have not ruled on Diageo’s motions to dismiss. All three lawsuits remain pending. No trial dates have been set, and no settlements have been announced. |
Tequila Law and Why the Don Julio False Advertising Lawsuit Matters
To understand why these lawsuits carry real legal weight, you need to understand the regulatory framework around tequila production.
Tequila is a protected designation of origin, like Champagne or Scotch. It can only be produced in specific regions of Mexico, primarily the state of Jalisco. The production process and labeling requirements are governed by NOM-006, Mexico’s official tequila standard, which is enforced by the Consejo Regulador del Tequila, known as the CRT.
Under NOM-006, tequila labeled as “100% agave” must be produced using only Blue Weber agave as its sugar source. No cane alcohol, no other sugar-derived spirits. A product that mixes agave tequila with cane alcohol falls into the “mixto” category, which can legally contain up to 49% non-agave sugars, but it cannot be marketed as 100% agave.
Under U.S. import and labeling regulations, products sold in America must accurately represent their contents. The Alcohol and Tobacco Tax and Trade Bureau (TTB) regulates alcohol labeling in the United States and has its own certification requirements for imported spirits. A tequila that misrepresents its agave content on a label sold to American consumers would potentially violate both TTB regulations and state consumer protection laws.
The lawsuits also raise a significant secondary question: if the testing results are accurate, did the CRT’s certification process fail? Plaintiffs suggest that either the oversight system broke down or that there was inadequate enforcement, leaving American consumers without the regulatory protection they assumed was in place.
Don Julio Class Action Lawsuit Sign Up: Who Can Join?
If you purchased Don Julio or Casamigos tequila in the United States, you may be part of the affected class of consumers. Here is what you need to know about eligibility.
The class period has not been formally defined yet because the cases are still in early litigation stages. However, based on the complaints and comparable class actions, purchases made in approximately 2020 through 2025 are the most likely target window. The exact class period will be confirmed by the court if and when the cases proceed to class certification.
You do not need a physical receipt to potentially participate. Consumer class actions routinely accept claims from people who can provide credit card statements, bank records, delivery app order histories, or even a sworn statement confirming their purchase. Digital purchase records from services like Drizly, Instacart, or Total Wine can serve as documentation.
| Eligibility Factor | What It Means for You |
|---|---|
| Purchase location | Must have bought in the United States |
| Product purchased | Don Julio or Casamigos tequila products |
| Time period | Approximately 2020 through 2025 (to be confirmed) |
| Type of buyer | Personal consumer, not a bar or restaurant buying for resale |
| Documentation needed | Helpful but not required for basic claim filing |
| Legal action required | None – class membership is passive unless you opt out |
One thing worth understanding: as a class member, you do not need to hire your own attorney or do anything active to be included. Once a class is certified and a settlement is reached or a verdict entered, you will receive notice and an opportunity to file a claim. The only active step that excludes you from the class is affirmatively opting out, which you would only do if you wanted to pursue an individual lawsuit against Diageo instead.
Which Don Julio Products Are Named in the Lawsuit?
The following Don Julio and Casamigos products have been specifically identified in the lawsuits based on the lab testing and complaint filings:
| Product | Type | Why It Is Named |
|---|---|---|
| Don Julio Blanco | Unaged / Silver tequila | Lab testing in California RICO case |
| Don Julio 1942 Anejo | Aged luxury expression | Lab testing in California RICO case |
| Don Julio Reposado | Aged 8 months | Named in class complaints |
| Don Julio 70 Cristalino | Filtered anejo | Named as part of brand-wide claims |
| Casamigos Blanco | Unaged silver tequila | Lab testing: ~33% agave ethanol found |
| Casamigos Reposado | Aged 7 months | Lab testing: ~42% agave ethanol found |
The Don Julio 1942 lawsuit aspect is particularly significant. Don Julio 1942 is the brand’s flagship prestige product, retailing for $150 to $200 per bottle. When consumers spend that kind of money on what they believe is an ultra-premium, authentically produced tequila, and lab tests suggest it may contain only 33% agave-derived alcohol, the financial and reputational stakes are high on both sides.
Don Julio Lawsuit Update 2026: Where Things Stand Right Now
As of June 2026, all three class action lawsuits against Diageo remain active in the federal court system. Here is the current status of each case:
The New York lawsuit is pending in the Eastern District of New York. Diageo filed its motion to dismiss in November 2025. As of this writing, the court has not issued a ruling on that motion. If the motion is denied, the case moves to discovery, where plaintiffs could potentially compel Diageo to turn over internal production records, communications, and other documentation.
The Florida lawsuit is pending in the Southern District of Florida. Diageo filed its motion to dismiss in October 2025. No ruling has been issued. The Florida case is particularly interesting because, if it survives dismissal, the plaintiff’s side has already signaled it plans to conduct its own independent laboratory testing rather than relying solely on the results from the third-party European lab cited in the California complaint.
The California RICO lawsuit is pending in the Northern District of California (San Francisco). This is the most complex of the three cases because of the RICO claim and the potential for triple damages. Courts tend to apply stricter pleading standards to RICO cases, meaning the California case faces a higher bar to survive the motion to dismiss stage, but also carries the largest potential recovery if it succeeds.
| Lawsuit | Court | Status as of June 2026 |
|---|---|---|
| New York class action | EDNY | Pending – dismissal motion under review |
| Florida class action | SDFL | Pending – dismissal motion under review |
| California RICO case | NDCA | Pending – RICO standards apply |
| Settlement | N/A | No settlement announced as of June 2026 |
| Trial dates | N/A | None set for any of the three cases |
The most significant event that will shape the trajectory of these cases is the court rulings on Diageo’s motions to dismiss. If any of the three courts deny the motions, the case enters discovery and the litigation becomes far more expensive for Diageo and far more revealing for the public.
If any court grants the motion to dismiss, the relevant plaintiff has the option to amend their complaint and refile with stronger factual allegations, or to appeal the dismissal. These cases are not over with a single procedural ruling.
Don Julio Lawsuit Settlement: What Could Consumers Expect?
No settlement has been announced in any of the three Don Julio and Casamigos lawsuits as of June 2026. Any discussion of settlement figures is necessarily speculative at this stage. However, comparable alcohol labeling class action settlements offer some context for what might eventually happen if Diageo chooses to resolve these cases rather than litigate them to judgment.
Consumer class actions in the premium spirits category involving labeling fraud or false advertising claims have settled in recent years for amounts ranging from a few million dollars to tens of millions, depending on the size of the class, the strength of the evidence, and the financial exposure of the defendant.
Diageo is a global company with annual revenues exceeding $16 billion. Its financial capacity to settle is not in doubt. What matters more is the strength of the scientific evidence, the willingness of courts to allow these cases to proceed past the dismissal stage, and whether the litigation becomes sufficiently damaging to brand reputation that an out-of-court resolution becomes preferable to continued public legal battles.
Individual payouts in any eventual settlement would depend on the total settlement fund, the number of qualifying claimants who file, and the documentation those claimants provide. Based on comparable cases, per-person recoveries in consumer class actions of this type typically range from modest amounts for undocumented claimants to higher amounts for people with receipts proving multiple purchases of premium expressions like Don Julio 1942.

What the Don Julio Tequila Lawsuit Means for the Entire Industry
The lawsuits against Don Julio and Casamigos are not happening in isolation. They are part of a broader reckoning inside the tequila industry that has been building for years.
Agave prices surged dramatically over the past decade as the global popularity of tequila and mezcal exploded. The worldwide demand for tequila has consistently outpaced the supply of mature Blue Weber agave plants, creating powerful financial pressure on producers to find alternatives. Industry observers, agave farmers, and small distillers have been raising concerns about adulteration for several years.
In early 2025, before the lawsuits were filed, Mexican media reported that agave growers in Jalisco demonstrated publicly against tequila companies, protesting what they described as the use of non-agave ingredients in products that were then exported and marketed as 100% agave spirits. Those demonstrations were part of what prompted the initial legal investigation that led to the New York complaint.
If the laboratory findings at the center of these lawsuits prove accurate and courts allow the cases to proceed, it could trigger a wave of similar litigation across the premium tequila industry. It could also prompt regulators in both Mexico and the United States to significantly tighten their testing and certification protocols for imported tequila.
For consumers, the stakes are simple. When you pay premium prices for a spirit because of what its label promises, that label should be truthful. The Don Julio and Casamigos class action lawsuits represent an attempt by ordinary consumers to hold one of the world’s largest alcohol companies accountable for what those labels say.
Frequently Asked Questions About the Don Julio Lawsuit
Is there really a lawsuit against Don Julio tequila?
Yes. Three separate federal class action lawsuits have been filed against Diageo North America, the owner of Don Julio, in New York, Florida, and California. All three were filed between May and July 2025. The cases allege that Don Julio tequila labeled as “100% agave” contains significant amounts of non-agave alcohol.
What is the Don Julio and Casamigos lawsuit about?
The lawsuit accuses Diageo North America of marketing and selling both Don Julio and Casamigos tequilas as “100% agave” products while allegedly using cane alcohol or other non-agave spirits in the actual production. Independent lab testing reportedly found that some tested products contained as little as 33% agave-derived ethanol, far below the 100% claimed on the label.
How do I sign up for the Don Julio class action lawsuit?
As of June 2026, no formal claims process is open because no settlement has been reached and no class has been formally certified by a court. The cases are still in early litigation. If the lawsuits proceed and a settlement is reached, a settlement administrator will open a claims portal and affected consumers will receive notice. You can monitor the progress by following updates from Hagens Berman, the law firm handling the New York case, at hbsslaw.com.
Does the Don Julio 1942 lawsuit affect that specific product?
Yes. Don Julio 1942 Anejo is one of the products that was specifically tested in the California lab analysis. The lawsuit alleges that samples of Don Julio 1942 Anejo contained approximately 33% agave-derived ethanol, which is starkly below the 100% claimed on the label. Given the $150 to $200 retail price of a bottle of 1942, the alleged price premium paid by consumers is substantial.
What is Diageo saying about the Don Julio lawsuit?
Diageo has denied all allegations. The company states that all of its Casamigos and Don Julio tequilas labeled as “100% agave” are made from 100% Blue Weber agave and comply with Mexico’s NOM-006 tequila production standard. Diageo filed motions to dismiss all three lawsuits in late 2025, calling the claims implausible and the laboratory testing scientifically unvalidated. The courts had not ruled on those motions as of June 2026.
