A coalition representing more than 100 large and small American single malt whiskey producers sent a letter to the Treasury Department’s Tax and Trade Bureau (TTB) urging the bureau to finalize the official standard for this category, which stands as one of the fastest-growing categories of American whiskey over the past decade. The letter, sent on behalf of the Distilled Spirits Council of the United States and the American Single Malt Whiskey Commission, marked the two-year anniversary of TTB’s notice of proposed rulemaking to establish a standard of identity for American single malt whiskey. The coalition noted that in addition to producers, consumers will benefit from a clear definition of what constitutes American single malt whiskey.
