A nice addition to plain sparkling water

I had been using a Sodastream for about 6 months before I picked up an additive for it. I chose one of their "waters" because everything else at the time was full of Aspartame or sucralose and I avoid that as much as I can. The flavour I picked up is Apple Peach and I quite like it - gives a nice mild flavour with not too much sweetness. I still drink the water plain, for the most part, but this is a nice change once in a while. It makes an especially nice addition to white sangria.
