Global spirits giants sit on $22B unsold inventory amid demand slowdown

Major spirits companies are grappling with a $22 billion inventory glut, the largest in a decade, according to the Financial Times. Diageo, Pernod Ricard, Campari, Brown-Forman and Remy Cointreau are sitting on unprecedented amounts of unsold aged spirits, including whisky, Cognac, tequila and rum. The surplus stems from pandemic-era over-production when home consumption surged. However, consumer demand has since declined due to health concerns and shifts towards THC beverages. Companies have responded by pausing production at distilleries, reducing workforces and closing facilities. Cognac faces particularly severe challenges, with slowing exports and trade issues with China forcing price cuts. Even tequila, which recently outsold American whiskey in the US, is experiencing slowdown. Industry analysts warn that production cuts risk future shortages if demand rebounds unexpectedly.
