This recipe requires advance preparation. The night before or at least 6 hours prior to serving, make ice cubes or an ice ring by pouring 1 liter of ginger ale into the desired container and freezing. Pour the brandy, pomegranate juice and schnapps into a large punch bowl. Just prior to serving, gently add the Champagne and the remaining 2 liters of ginger ale. Float the prepared ice cubes or ring in the bowl. Serves a crowd.
