Rye whiskey is a type of whiskey that is made primarily from rye grain, which must constitute at least 51% of the mash bill. This grain gives rye whiskey its distinctive spicy and fruity flavor profile. It is typically aged in charred oak barrels, which adds complexity and depth to its taste. Rye whiskey is popular in various cocktails, including the classic Manhattan and Sazerac. It is produced in several regions, with notable styles coming from the United States and Canada. Each region has its own regulations and flavor characteristics, contributing to the diversity of rye whiskey available today.
