Heat the grape and lemon juice as well as the wine, add the sweetener and soaked gelatine. Stir until the gelatin is dissolved. Then put the liquid in the refrigerator for about 1 hour, stirring occasionally.
In the meantime, prepare the berries, halve or quarter large fruits such as strawberries. Then mix the berries with the gelling liquid and fill the bundt cake molds. Let stand in the refrigerator overnight.
To remove the berry jelly from the molds, briefly dip the silicone molds in hot water before turning them over.
If you don`t like wine, you can replace it with grape juice.
