I was trying to buy one of those Soda Stream machines but while inquiring about the refill bottles I stumbled on something about kefir being a better and cheaper alternative. I ordered the grains, I’m on my fourth batch and I’m finally getting some carbonisation after using some cane sugar.Tibicos, or water kefir, is a traditional fermented drink made with water and a symbiotic culture of bacteria and yeasts held in a polysaccharide biofilm matrix created by the bacteria. It is sometimes consumed as an alternative to milk based probiotic drinks or tea-cultured products such as kombucha.
