What's the difference between bourbon and whisky?

Bourbon is a type of whiskey that is made primarily from corn, while whisky is a broader category that includes various types of distilled spirits made from grains like barley, corn, rye, or wheat. Bourbon is specifically made in the United States and has specific production regulations, such as being aged in new charred oak barrels. Whisky, on the other hand, can be made in different countries and may have different production methods and regulations.
