What are the key differences between whiskey and bourbon whiskey?

Whiskey and Bourbon whiskey are both types of distilled spirits made from fermented grains, but there are key differences between the two. Bourbon whiskey must be made in the United States, primarily from corn, and aged in new charred oak barrels. It also has specific requirements for distillation and aging. Whiskey, on the other hand, can be made anywhere in the world and has more flexibility in terms of ingredients and aging processes.
