What distinguishes whiskey from bourbon in terms of their production and flavor profiles?

Whiskey and Bourbon are both types of distilled spirits made from grains, but bourbon is a specific type of whiskey that must meet certain legal requirements. Bourbon must be made in the United States, contain at least 51 corn in its MASH bill, and be aged in new charred oak barrels. This gives bourbon a sweeter and smoother flavor profile compared to other types of whiskey.
