No! Only water should be carbonated in the SodaStream Sparkling Water Maker. You risk damaging your Sparkling Water Maker, not to mention making a big fizzy mess! The money-back guarantee and the warranty are both invalidated if you carbonate any liquid other than water in your Sparkling Water Maker. Stick with plain, cold water and adding any one of our fantastic flavours AFTER the water has been carbonated!
The hermetic seal on the caps of our carbonating bottles keeps your sparkling water or flavored sparkling water from going flat as quickly as ordinary store-bought beverages. If you ever need to re-carbonate your plain sparkling water, you can. Just make sure that the water reaches the fill line on the carbonating bottle. If you've already prepared a drink with flavour, you cannot re-carbonate.
Remember
Always fizz water before adding flavour
