Which cocktail is known for its use of rye whiskey and vermouth?

The cocktail that is known for its use of rye whiskey and vermouth is the Manhattan. This classic cocktail is traditionally made with rye whiskey, sweet vermouth, and a dash of bitters, then stirred and strained into a chilled glass. The combination of the spicy notes from the rye whiskey and the sweetness of the vermouth creates a well-balanced and flavorful drink that has been a favorite since its inception in the late 19th century.

In contrast, the Martini primarily features gin and dry vermouth, which gives it a completely different flavor profile. The Old Fashioned is made with bourbon or rye whiskey, muddled sugar, and bitters, without vermouth. Lastly, the Rob Roy is a variation of the Manhattan, but it specifically uses Scotch whisky instead of rye, which differentiates it from the classic Manhattan made with rye whiskey.
