For the past decade, tequila has been on an absolute tear in the United States. In 2017, there were just six brands selling over 1 million cases per year in the U.S. Last year, there were over a dozen. But according to new data from The Spirits Business (TSB), agave spirits sales could be slowing down. While tequila is still growing in the U.S. — it was one of only two spirits categories to improve in the U.S. in 2024 — its margin of growth last year was much smaller than in years past.
