Pour the rosé wine into a large, shallow container and place it in the freezer.
Freeze the rosé for at least 4 hours, until it becomes firm and slightly icy around the edges.
Once frozen, use a sharp knife to cut the rosé into chunks or small cubes.
Add the rosé chunks, mixed berries, and honey into a blender.
Blend on high until the mixture is smooth and slushy, with a vibrant pink color and berry aroma filling the air.
Pour the frozen rosé slushie into glasses and garnish with a few fresh berries if desired.
