I mostly sprudle water with the Sodastream and then give a flavor to it. Genial is to "tune" also, other juices with the flavors ...
The flavors give the water a pleasant, subtle taste, but which is clearly perceptible, makes the sparkling water and interesting (at least to me) makes a good mood. Exactly that is a great alternative to juices that are usually heavily sugared.
My favorite is definitely lemon-lime. The best combination so far: syrup "blackcurrant, apple" mixed with lemon-lime of Aromhuset :-)
My Ranking:
1. Lemon-Lime
2. Currant
3. Raspberry
4. elderberry
5. Walderdbeere
And more honest than "if they want sweet soda pops, then buy this product not" one can not apply the product.
