STIR all ingredients with ice and strain into ice-filled glass.
Orange zest twist
Subtle vermouth and falernum sweetness takes the edge off this after-dinner whiskey charged, sipper of a cocktail.
Adapted from a cocktail discovered in May 2017 at Soho House, Berlin, Germany. Herbst is the German word for autumn/fall and also refers to harvest time so this drink translates as Sherry Harvest.
