Clase Azul v. Casa Azul: Different Bottles Don’t End a Trademark Fight
A luxury tequila in a hand-painted decanter and a tequila cocktail in a can may look nothing alike, but consumers could still think the same company makes both. That possibility sits at the center of the Clase Azul trademark dispute with Casa Azul, and it explains why different packaging, prices, and target customers did not end the lawsuit.
In Casa Tradición S.A. de C.V. v. Casa Azul Spirits, L.L.C., No. 24-20255 (5th Cir. Nov. 4, 2026), a divided Fifth Circuit vacated a judgment favoring Casa Azul following a bench trial. The majority directed the district court to “reassess” the likelihood of confusion after correcting errors in its analysis. Clase Azul therefore secured another opportunity to pursue its claims, although the appellate court did not enter an infringement judgment. Slip op. at 47–48.
The most useful part of the decision for beverage businesses concerns product expansion. Casa Azul sells bottled tequila and canned tequila sodas, while Clase Azul sells substantially more expensive tequila in distinctive ceramic decanters. The majority concluded that those differences did not justify treating the products as unrelated: both companies sell bottled tequila at 40% alcohol, and consumers could reasonably believe Clase Azul had “expanded its product line to include a tequila soda product.” Id. at 28–29.
That reasoning matters when a supplier launches a ready-to-drink cocktail or a distributor evaluates a new brand. A customer can understand that a can contains a different drink from the expensive bottle across the aisle while still assuming that the bottle’s producer launched, licensed, or sponsored the canned product. From that perspective, a different package and a lower price may look like a familiar brand entering another market.
The court’s treatment of the name itself reinforces the need for a careful trademark review. The majority rejected the classification of Clase Azul as merely descriptive and instead called the mark “suggestive,” explaining that consumers must use some imagination to connect the name to blue agave and tequila. For a supplier assessing a competing name, that analysis cautions against assuming that a reference to an ingredient leaves the entire brand name with little protection. Id. at 12–14.
Beyond those legal distinctions, the record showed how people actually understood the brands. A distributor employee thought Casa Azul represented a new Clase Azul product line, and a bar owner asked whether Casa Azul belonged to Clase Azul. One customer even posted a negative review on a Clase Azul product listing while uploading a photograph of Casa Azul. The majority described these incidents as “real confusion in the market,” making the communications from distributors and retailers particularly useful evidence. Id. at 40–41.
Even so, the decision leaves Casa Azul with arguments to make on remand. The majority described the trial court’s assessment of the marks’ similarity as “not clearly erroneous,” preserving that part of the analysis while requiring the court to reconsider the overall result. Different bottles and branding still matter; they must be evaluated alongside the other evidence. Id. at 47.
For suppliers, the practical lesson starts before launch: trademark clearance should consider plausible product extensions and affiliations across beverage categories. Wholesalers and distributors can help by preserving mistaken inquiries, retailer listings, photographs, and customer messages, with enough context to explain who encountered the product and what caused the misunderstanding. Distinctive packaging helps customers recognize what they are buying, but the trademark analysis also asks whose company they think stands behind it.
