Fill a glass pitcher halfway with ice and add the chopped fruits. Tilt the pitcher and pour the cava very slowly down the side; this will help retain the bubbles. In another pitcher or bowl with spout, combine the brandy, Licor 43, white grape juice, and sugar, then pour the mixture into the sparkling wine and fruit. Give a quick stir and add the mint sprig. When serving, make sure each glass gets some ice and fruits.
