On May 13, 2013, Tennessee Governor Bill Haslam signed House Bill 1084, requiring the Lincoln County process to be used for products produced in the state labeling themselves as "Tennessee Whiskey", with a particular exception tailored to exempt Benjamin Prichard's, and including the existing requirements for bourbon. As federal law requires statements of origin on labels to be accurate, the Tennessee law effectively gives a firm definition to Tennessee whiskey, requiring Tennessee origin, maple charcoal filtering by the Lincoln County process prior to aging, and the basic requirements of bourbon (at least 51% corn, new oak barrels, charring of the barrels, and limits on alcohol by volume concentration for distillation, aging, and bottling).
