Rye whiskey is a type of whiskey that is made primarily from rye grain, which must constitute at least 51% of the mash bill. It is known for its spicy and fruity flavor profile, often featuring notes of pepper, citrus, and caramel. Rye whiskey can be produced in various regions, but it is most commonly associated with the United States and Canada. In the U.S., rye whiskey must be aged in new charred oak barrels and distilled to no more than 160 proof. The production process and aging contribute to its distinct taste and character. Canadian rye often has a different style, typically being smoother and lighter, and may contain a blend of grains.
