Rye whisky is a type of whisky made primarily from rye grain, which gives it a distinct spicy flavor. To be classified as rye whisky in the United States, it must contain at least 51% rye in its mash bill. It is typically aged in charred oak barrels, which contributes to its rich color and complex taste. In Canada, rye whisky can include a blend of grains, but it often features a higher proportion of rye. This style is known for its smoothness and versatility, making it popular in cocktails like the Manhattan and Old Fashioned.
