What decision allowed whiskey to be made from grain, not fruit or molasses, establishing definitions for bourbon and rye?

The Taft Decision, which refers to a ruling made during the administration of President William Howard Taft, was significant because it established clear definitions for different types of whiskey, including bourbon and rye. This ruling emphasized the importance of using specific grains—primarily corn for bourbon and rye for rye whiskey—rather than fruits or molasses, which were used in the production of other spirits like rum. By focusing on grain, the Taft Decision helped define what constitutes bourbon, thus laying the groundwork for many modern regulations and standards surrounding its production. This ruling was pivotal in differentiating traditional American whiskey styles and helped protect the identity and heritage of bourbon as a distinctly American spirit. Such historical decisions shaped the legal framework for whiskey production, which is crucial for producers and consumers alike in understanding and appreciating the nuances of the beverage.
