Soak gelatine in cold water. Drain the cherries in a sieve, collecting the juice. Beat eggs, sugar and vanilla sugar with the whisk of the hand mixer for about 5 minutes until frothy. Squeeze the gelatine, dissolve. Mix with wine and 50 ml cherry juice. Stir into the egg foam mixture and refrigerate for gelling.
Whip cream until stiff. As soon as the wine mixture begins to set, fold in the cream. Distribute the cherries into the glasses. Add the wine cream and chill for about 1 hour. Decorate with mint before serving
