Pour pomegranate juice and merlot into a 2 cup measuring glass. Add Splenda and set aside.
Smoosh berries so they release the juice, but not completely crushed. Keep them chunky. Equally distribute the berries between the popsicle molds. Add any remaining berry juice to the juice/merlot measuring cup.
Pour the juice/merlot mixture evenly between the popsicle molds. Use a bamboo skewer to release any air bubbles held by the berries. Place the lid on the popsicle mold and place sticks. If not using a mold, small paper cups can be used. Place in the freezer for 30-40 minutes, remove and then place sticks. Place in freezer until solid.
