Momo Kombucha, fermented in small batches (in glass jars!) in London. Momo are certified organic and a B-Corp too. It's unpasteurised, high in bacteria, and with a lil sediment in the bottom. It contains NO sweeteners or flavourings other than a smidge of juice. We first found this brand via The Zoe Podcast (see link below) and being the fountain of all gut knowledge - they know what's worth drinking.
