I like to just take a bottle of water and add some pure (not from concentrate) fruit juice, especially cranberry. The flavor of the juice is so strong that it doesn't take much to flavor the water at all. I use a 1.5 liter water bottle filled will water and add maybe 1/3 cup of pure cranberry juice to it. I'm thinking of trying this with carbonated water, too.
