Juice the lemons and zest one for added citrus aroma, then set aside.
Pour the chilled rosé wine into a freezer-safe container, leaving some space at the top for expansion.
Add the lemon juice, lemon zest, and sugar into the wine. Stir gently until the sugar dissolves completely, creating a vibrant, slightly frothy mixture.
Place the container in the freezer. Every 30 minutes, use a fork or spoon to scrape and stir the mixture to break up ice crystals and promote a uniform, sorbet-like texture. Repeat this process 3-4 times over 2 hours.
Once the mixture is fully frozen with a granular, icy texture, use a fork to scrape it into fluffy, spoonable servings.
Serve immediately in chilled glasses or bowls, garnished with extra lemon zest or a twist of lemon peel if desired. Enjoy this icy, fruity wine treat!
