What type of vermouth is used in a Dry Rob Roy?

A Dry Rob Roy is a variation of the classic Rob Roy cocktail, which itself is made with Scotch whisky. The key distinction in the Dry Rob Roy is the use of dry vermouth rather than sweet vermouth. This choice results in a drink that has a lighter and crisper flavor profile compared to the original, which traditionally utilizes sweet vermouth. In cocktails, the type of vermouth greatly influences the final taste, and opting for dry vermouth imparts a less sweet, more herbal and botanical flavor that complements the whisky. Thus, for a Dry Rob Roy, dry vermouth is the appropriate choice to achieve the desired characteristics of the drink.
