Mix and drink... couldn't be easier.
When choosing a soda to mix with your wine I find the generic store brands offer the best selection. A lemon lime or raspberry soda usually works well, but just about any soda or combination of sodas will do. Just avoid colas and root beers. They taste weird with wine. For the fizziest drinks, have both the wine and the soda chilled before you mix them.
