What is the typical alcohol base used in a Manhattan cocktail?

The typical alcohol base used in a Manhattan cocktail is Bourbon or Rye Whiskey. The Manhattan is a classic cocktail that originated in the late 19th century and is traditionally made using these types of whiskey. Bourbon, known for its sweeter profile, adds a rich and caramel flavor that complements the other ingredients, while Rye Whiskey, with its spicier character, adds depth and complexity to the drink.

Using either bourbon or rye is essential for achieving the distinct flavor profile that defines a Manhattan. The cocktail is typically mixed with sweet vermouth and aromatic bitters, and the whiskey serves as the backbone of the drink, balancing the sweetness of the vermouth and the herbal notes of the bitters.

The other options represent spirits that are not typically associated with a Manhattan. Vodka offers a neutral flavor that would not contribute to the characteristic taste of this cocktail. Rum, typically sweeter and more fruity, does not fit the flavor profile expected in a Manhattan. Gin, while a key ingredient in many cocktails, does not align with the traditional formulation of a Manhattan, which emphasizes the robustness of whiskey. Thus, Bourbon or Rye Whiskey is the correct choice as these are the spirits that define the Manhattan cocktail.
