For a Dry Manhattan, how much Dry Vermouth is used?

In a Dry Manhattan, the key characteristic is the use of dry vermouth, which distinguishes it from a traditional Sweet Manhattan that uses sweet vermouth. The standard measure for dry vermouth in a Dry Manhattan is typically very minimal—often as little as 2 to 3 drops. This small amount allows the vermouth to subtly enhance the flavor of the whiskey without overpowering it. Essentially, the goal is to achieve a drier taste profile, thus the use of just a few drops serves well to achieve this balance.

While some might think of using a specific volume like 1/4 oz or 1 oz, these amounts would result in a cocktail that is not in line with the traditional preparation for a Dry Manhattan. Using no vermouth at all would detract from the essence of the cocktail, as vermouth is essential for defining its style and taste. The precision in the amount of dry vermouth used is what makes this cocktail unique.
