Mexico is sitting on more than half a billion litres of tequila in inventory, almost as much as its annual production, as the fast-growing industry reckons with slowing demand and the prospect of tariffs on exports to the US under Donald Trump.

By the end of 2023, the industry had 525mn litres of tequila in inventory, either ageing in barrels or waiting to be bottled, according to data shared with the Financial Times by the Tequila Regulatory Council. Of the 599mn litres of tequila produced last year, about one-sixth remained in inventory, according to the figures.

“Much more new spirit is being distilled than is being sold, and inventories are starting to accumulate,” said Bernstein analyst Trevor Stirling, attributing the build-up to falling demand and new distillery capacity that has recently begun operating in Mexico. “The tequila industry is set for a very turbulent 2025.”
