I've just been using the little squirt bottles of water flavoring (Mio, Dasani, and a number of other brands) with our SodaStream. Works like a charm for me. They tend to be fruit-flavored but that's what I prefer anyway. Just shoot them in your glass, not in the bottle. I find it easier to get the variety that way - don't have to commit to a flavor for a whole bottle & no need for multiple bottles in the fridge.
