Bring up to the boil and stir until the sugar is completely dissolved. Remove from the heat. Squeeze excess water out of the gelatine and add to the hot grape juice. Stir through until the gelatine is completely dissolved. Set aside to cool for about 10 minutes. Add the remaining 250ml Grapetizer and liqueur to the warm juice and stir through gently to retain some of the bubbles. Pour into a mould and refrigerate until set.To make the pannacotta, soften the gelatine as per above. In a saucepan, heat together the cream, vanilla seeds and castor sugar.
