The short answer is no. Kombucha and kefir water are more like cousins: they belong to the same family, but they’re very different in appearance and temperament. Both fermented, probiotic-rich beverages, each has its own distinctive flavour profile and mouthfeel.
Kombucha is made using green or black tea, steeped with sugar and often flavoured with fruits or berries. This infusion is then fermented using a symbiotic culture of bacteria and yeast (scoby) to produce a slightly fizzy, faintly acetic drink.
During the ferment, the kombucha scoby converts most of the alcohol (and some more of the sugar) into beneficial acids. As a fermented drink, kombucha contains live cultures, weighing in at roughly 100 million per 100ml.
100 million may sound like a lot, but that’s small fry compared to kefir water. Agua de Madre has billions of live cultures per 100ml, is the best option for those keen on boosting their gut’s live culture count.
While kefir water is also made with a scoby, it’s very different to the bacteria & yeast formation used to make kombucha. A kombucha scoby looks like a large, opaque, gelatinous disk, while the kefir grains we use to brew Agua de Madre are small, clear and crystalline.
