Final answer:
The September festival celebrated in Bardstown, Kentucky, is dedicated to whiskey. Specifically, the festival honors bourbon, a type of whiskey that benefits from the limestone-filtered water in Kentucky, ideal for its production.
Step-by-step explanation:
The liquor in question that is celebrated at a September festival in Bardstown, Kentucky is whiskey. This event corresponds with the famous Kentucky Bourbon Festival. This festival is a tribute to Kentucky's history and love for bourbon, a type of American whiskey that must be made with at least 51% corn and aged in new charred oak barrels. Kentucky's unique natural resources, particularly the limestone-filtered water, are ideal for whiskey and bourbon production.
Although some regions known for producing these spirits, such as Lynchburg, Tennessee, are situated in dry counties where the sale of these spirits is prohibited, they are still significant sites for distillation. The Jack Daniels brand, for instance, produces over 10 million cases a year in Lynchburg, a dry county.
