An article published in the [NKy Tribune](https://nkytribune.com/2026/05/our-rich-history-what-is-whiskey-the-taft-decision-still-the-basic-law-today/) explores how President William Howard Taft's 1907 decision defining "whiskey" continues to govern the spirits industry more than a century later. Taft's ruling resolved a contentious debate between traditional bourbon distillers in Kentucky and Cincinnati rectifiers who blended and flavored spirits.

The conflict emerged because rectifiers purchased whiskey in bulk from Kentucky distilleries and altered it with additives, while traditional distillers aged spirits in charred oak barrels. Cincinnati became a leading hub for rectified whiskey, while Kentucky focused on the more expensive aging process. The two business models collided when the 1906 Pure Food and Drug Act required clearer labeling but left room for interpretation about what constituted "whiskey."

The Roosevelt administration initially ruled that only aged whiskey could use that term, forcing rectifiers to label their products as "imitation." However, Congressional pressure from rectifier strongholds prevented consensus, leading President Taft to intervene. His solicitor general gathered 1,200 pages of evidence. After months of study, Taft issued his decision on December 26, 1907, making front-page news nationwide.

Taft ruled that any spirit made from grain could be called whiskey, whether aged or rectified, but each bottle must clearly describe what type it contained. [Taft wrote that "every bottle labeled as whiskey must include a description of its additives"](https://www.presidency.ucsb.edu/documents/decision-the-meaning-the-term-whisky-under-the-pure-food-act-and-the-proper-regulations) to prevent consumer fraud. Straight whiskey could be labeled as such, while rectified or neutral spirit whiskeys had to be transparently identified.

The decision satisfied neither side completely, but both accepted it. Today's bourbon regulations—requiring at least 51 percent corn, aging in new charred oak barrels, and prohibition of added coloring agents—trace directly to Taft's framework. [Kentucky produces more than 95 percent of the nation's bourbon](https://kybourbon.com/industry/faq/), with nearly 10 million barrels aging in state warehouses.

"The way to remedy this evil is not to attempt to change the meaning and scope of the term 'whiskey' accorded it for one hundred years," Taft wrote, "but to require a branding connection with the use of the term 'whiskey' which will indicate just what kind of whiskey the package contains." His insistence on labeling transparency established a consumer protection principle that endures in modern spirits regulation.
