This cocktail is technically a reverse Manhattan, which means instead to the standard of two parts whiskey and one part sweet vermouth, it’s 2:1 vermouth to whiskey. While you could use a good entry-level sweet vermouth like Dolin, this recipe will benefit from using vermouth with some added complexity. For those who prefer rye over bourbon, I’d suggest Cocchi Vermouth di Torino in place of Carpano Antica. Since this cocktail does not contain any fresh juices, it’s also the perfect candidate to store in a 1-liter swing-top bottle in the freezer.
