MOMO Kombucha's Tomlinson's Forced Rhubarb Kombucha is a limited-edition alcohol-free kombucha brewed and bottled at the brand's London brewery, made in collaboration with Natoora. It is built on a kombucha culture and left live and unfiltered, so the fermenting cultures stay in the bottle rather than being strained out. The rhubarb is forced rhubarb supplied by Robert Tomlinson.
