For the Bellini with berries, pour the sorted berries into thick-walled glasses (whisky tumbler or large long drink glass) and sprinkle with the liqueur. Peel the peaches to taste and cut into 5 mm cubes.
Marinate with powdered sugar and then spread evenly over the berries. Carefully pour the Bellini with berries with sparkling wine or champagne so that the peaches are not swirled.
