Buy flavors everywhere! Any water enhancer, whether powdered or liquid works. You use this system only to carbonate the water. All flavor additions are mixed in a different container.
Thank you for your question. Use only SodaStation flavored syrups. You may purchase different flavored syrups either through our website www.hamiltonbeach.com or through our customer service center 800.851.8900. You may also find SodaStation syrups in your local Walmart.
I buy liquid syrups in the local Walmart, for about $5.
Fruit syrups, such as blackberry or blueberry are available online, but much more expensive. Local grocers may have such syrup.
Powdered flavors would certainly work as well.
I buy sodastream since this brand has been discontinued. Sodastream is a liquid.
Epfan, my son and I use regular drink flavor like the to go Pouches in powder from Kool Aid or Ice tea, etc, last time we use Crunch in powder (at any regular store) and it actually tasted like Orange Crunch. Add the flavor after you add the Co2 according to instruccions.
There are flavors made specifically for this purpose, and it's liquid, it comes in bottles and you add it measuring with the cap. It's like a syrup. You can buy it at walmart or amazon, bed bath beyond etc. There are different brands. But like I said you can use anything to flavor it, from real fruit to powder flavor cause the flavor is added later and is never in touch with the mechanism of the fizzini.
