What type of vermouth is used in a Dry Manhattan?

In a Dry Manhattan, dry vermouth is specifically used as it complements the whiskey (typically rye or bourbon) to create a balanced cocktail. The key characteristic of dry vermouth is its lower sugar content compared to sweet vermouth, which allows for a drier taste profile in the finished drink. This balance of flavors is essential to achieving the classic Dry Manhattan, providing a clean and crisp flavor that enhances the overall drinking experience.

While sweet vermouth is prominent in the traditional Manhattan, the dry version substitutes that sweetness with dryness, making it suitable for those who prefer less sweetness in their cocktails. White and herbal vermouths do not typically align with the flavor profile desired in a Dry Manhattan, as they may introduce unwanted flavors and sweetness or differ significantly from the classic taste.
