What is the main whiskey used in a Manhattan cocktail?

The primary whiskey traditionally used in a Manhattan cocktail is straight rye whiskey. This choice plays a significant role in defining the flavor profile of the drink, which is known for its balance of sweetness from the vermouth and the spiciness of the rye. Rye whiskey carries a distinct character that adds complexity and depth to the Manhattan, making it a favorite among enthusiasts.

While bourbons can also be used in variations of the Manhattan, the classic recipe emphasizes rye whiskey due to its historical roots in the cocktail's origin. The spiciness of the rye complements the sweetness of the sweet vermouth and the aromatic bitters, resulting in a harmonious and well-known cocktail.

The other options, such as Irish whiskey and blended Scotch whisky, do not traditionally belong in the Manhattan mix; they impart different flavor profiles that do not align with the cocktail's intended taste. Therefore, straight rye whiskey is recognized as the quintessential base for a Manhattan.
