What are the key differences between whisky and bourbon, and how do they affect the flavor profiles of each?

Whisky and Bourbon are both types of distilled spirits made from grains, but they have some key differences. Bourbon is a type of whisky that must be made in the United States and is primarily made from corn, while whisky can be made anywhere in the world and can be made from a variety of grains. Bourbon is aged in new charred oak barrels, which gives it a sweeter and smoother flavor profile with hints of caramel and vanilla. Whisky, on the other hand, can have a wider range of flavors depending on the grains used and the aging process, but often has a more complex and robust flavor profile with notes of smoke, fruit, and spice.
