Peel the pomegranate and take out the seeds. Smash pomegranate seeds in a bowl, carefully. Put strainer at the top of the pitcher, transfer the seeds and juice to the strainer. Rub the seeds on the strainer with the back of a spoon to get the rest of the juice out.
Add the wine and liquor to the pitcher. Stir well. (You may refrigerate it at this point to be used later or serve right away.)
Add the 7-Up and lightly stir. (Add soda right before serving so it doesn't go flat.)
