Bourbon and Tennessee whiskey are two types of American whiskey that are made from corn. Bourbon must be made from at least 51% corn, while Tennessee whiskey must be made from at least 80% corn. Both types of whiskey are aged in oak barrels, but bourbon must be aged for at least two years, while Tennessee whiskey must be aged for at least four years. Bourbon has a sweeter flavor than Tennessee whiskey, due to the higher percentage of corn used in its production. Tennessee whiskey has a smoother flavor, due to the extra filtration process that it undergoes before it is bottled.
Bourbon and Tennessee whiskey are both popular choices for cocktails and mixed drinks. Bourbon is often used in Old Fashioneds and Manhattans, while Tennessee whiskey is often used in Jack and Cokes and Whiskey Sours. Both types of whiskey can also be enjoyed neat or on the rocks.
