Symbiota offers the widest range of well-nurtured & resilient fermentation cultures grown under license. Our cultures are fed right up to the time of dispatch.  Kombucha SCOBYs can tolerate being refrigerated for up to 2 weeks before fermenting them. It is best to ferment all other cultures soon after receiving them. If you are slightly delayed it is best to place the culture in the fridge. If you do not plan on fermenting your culture within 3 days of receiving it, it is best to order dried cultures.   International orders will be sent dried cultures.
