Wash the grapes, pluck and drain them. Soak gelatine in cold water. Warm the wine, juice and sugar while stirring until the sugar is dissolved. Squeeze the gelatine and dissolve in the warm liquid. Spread the grapes, except for some for decoration, in 4 glasses (each containing approx. 250 ml). Pour wine mixture on top.
Chill for at least 4-5 hours. Coarsely chop the almonds, cut the set aside grapes in half. Whip the cream until stiff, allowing the vanillin sugar to trickle in. Distribute the cream as a blob in the glasses. Decorate with almonds and grapes
waiting time approx. 4 hours
