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

Bourbon is a type of whiskey that is made primarily from corn, while whiskey 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 compared to whiskey. Whiskey, on the other hand, can have a wider range of flavors depending on the grains used and the aging process. The differences in ingredients and aging methods contribute to the distinct flavor profiles of bourbon and whiskey.
