The Kentucky bourbon industry is a vital part of the state's economy and culture. Bourbon is a type of whiskey that must be made from at least 51% corn and aged in new charred oak barrels. Kentucky produces about 95% of the world's bourbon, with many famous distilleries located in the region, such as Jim Beam and Maker's Mark. The industry has a rich history dating back to the late 18th century, when early settlers began distilling whiskey. Today, the Kentucky Bourbon Trail attracts tourists who want to explore the distilleries and learn about the bourbon-making process. The industry continues to grow, with new distilleries opening and innovative products being developed.
