Mix gelatin in 1/4 cup champagne and let it fully soften and dissolve.
Heat 1 cup champagne in a saucepan to a boil and mix in the sugar to completely dissolve. Remove from heat and mix in the gelatin mixture. Pour in the remaining champagne, mix thoroughly and set to cool over a bowl of ice.
Pour cooled mixture into wine or dessert glasses and chill for 45 mins to an hour till it's just barely setting. Arrange the fruit equally in all the glasses and chill till for 3-4 hours till completely set.
