The Alcohol & Tobacco Tax & Trade Bureau (TTB) in the US has officially recognized American single malt whiskies as a separate category, effective from January 19, 2025. This marks a significant milestone for American distillers, who have been producing single malt whiskies informally since the 1990s. The new regulations will mandate specific criteria for whiskies to be labeled as single malt. The announcement is anticipated to boost the category's global visibility and presence in markets, with existing producers expanding and more distilleries likely to introduce single malt offerings.
