Serve in glass punch cups, with 1-2 small ice cubes in each cup. If you like a greater sparkle, add a glass of club soda. This is the original of the now popular bottled wine drink. Classically, it is made with white wine and German champagne. The spiral of lemon peel, cut with the top of the lemon left on to be hung over the side of the punch bowl, is the "cold duck" that inspired the drink's name. The homemade version is an elegant far cry from the insipid bottled version.
