1 1⁄2 oz Irish whiskey, Jameson
              1 oz Sweet vermouth
              1⁄2 oz Herbal liqueur, Green Chartreuse
              1 T Agave syrup
              2 ds Orange bitters
          Instructions
    
          Vigorously stir together all ingredients in a lowball glass. Once fully mixed add a couple ice cubes. (Don't add ice cubes until after, prevents agave nectar from settling/separating).
