Measure out the chilled rosé wine and pour it into your blender.
Add the ice cubes to the blender, surrounding the liquid to help achieve a slushy consistency.
If you prefer a sweeter slushie, pour in a tablespoon or two of simple syrup.
Secure the lid on the blender and pulse on low speed a few times, then blend on high until the mixture is smooth, velvety, and well combined. Look for a semi-frozen, slushie texture that scoops easily.
Stop the blender, check the texture, and scrape down the sides if needed. If it’s too thick, add a splash of rosé and blend briefly.
Pour the frozen rosé slushie into chilled glasses, preferably pre-rinsed with ice for extra chilliness.
Garnish with fresh berries, thin slices of citrus, or a sprig of mint for visual appeal and added aroma.
Serve immediately with a straw or small spoon, enjoying the cool, refreshing, blush-colored treat that melts slowly on the palate.
