Which major city in Kentucky is known for its significant role in the Bourbon industry?

Louisville is recognized as a major hub for the Bourbon industry due to its historical and ongoing significance in the production and distillation of Bourbon whiskey. Located near the heart of Bourbon Country, Louisville houses some of the most famous distilleries, such as the Louisville-based Angel’s Envy and the historic Old Forester. The city also plays host to the Kentucky Bourbon Festival, which celebrates the state’s rich Bourbon heritage and attracts visitors from around the world.

In contrast, while Lexington and Bowling Green also have their own distilleries and contribute to the state's Bourbon production, Louisville’s prominence, both historically and economically, in the industry is unparalleled. Covington, on the other hand, is known more for its proximity to Cincinnati and does not have the same level of association with Bourbon. Thus, Louisville’s key role in the Bourbon industry makes it the correct answer.
