Natural Probio : where authentic fermentation meets lasting well-being.
Our kefir and kombucha shop gathers everything you need to ferment drinks at home. Every culture is reproduced in our workshop, checked by hand and travels in protective packaging designed to keep it fully alive.
100% live and active cultures, never freeze-dried powders. Every order from the kefir and kombucha shop includes a step-by-step guide, email support and a free replacement guarantee if your culture arrives damaged. More than 10,000 customers across Europe already ferment with us, with a 4.7/5 average rating on Trustpilot.
Pick your culture in the kefir and kombucha shop, grab a glass jar, water or milk depending on the ferment, and follow the included guide: within 24 to 72 hours you will pour your first homemade fermented drink. Not sure where to start? Our 5-question quiz points you in the right direction, and the history of kombucha tells you where this centuries-old tea comes from.
Do the cultures arrive alive? Yes, they leave our workshop the same day and easily handle 24/48h transport.
Do they last forever? With basic care, kefir grains and SCOBYs reproduce endlessly: it is a one-time purchase.
Behind this kefir and kombucha shop there is a workshop, not a warehouse. Each batch of grains is fed, checked and packed by hand the very day it ships. That is why our cultures arrive vigorous and start fermenting from the first brew, whether you choose milk kefir, water kefir or kombucha.
Every product page includes clear instructions, storage tips and real answers from our team. If you hesitate between two cultures, write to us: we reply within 24 working hours, in plain English. And because grains and SCOBYs reproduce endlessly, your first order is usually the only one you will ever need.
