What did the Taft Decision establish regarding whiskey production?

The Taft Decision established that whiskey must be made from specific grains, which affirms the grain composition essential for the production of whiskey. This ruling underscored the importance of adhering to traditional grain standards, particularly that a significant portion of the mash bill must consist of grains such as corn, rye, barley, or wheat. This decision helped to define the legal parameters for what constitutes whiskey, protecting the integrity of the spirit and ensuring that producers follow established guidelines related to ingredients.
