A Manhattan, when crafted using bourbon as its base spirit, results in a variation of the classic cocktail offering a distinctly sweeter and often spicier profile. This substitution modifies the inherent dryness found in rye-based Manhattans, lending a richer, more rounded character to the drink. The process involves combining bourbon, sweet vermouth, and bitters, typically Angostura, followed by stirring with ice and straining into a chilled glass, garnished with a maraschino cherry.
Employing bourbon significantly alters the sensory experience. The corn-based mash bill characteristic of bourbon imparts notes of caramel, vanilla, and oak, contributing to a more approachable and palatable cocktail for some palates. Historically, while rye was the traditional choice, bourbon gained popularity as access to different whiskies evolved, and preferences shifted toward sweeter flavor profiles in mixed drinks.
