MOMO Kombucha Zerbinati's Watermelon Kombucha is part of the brand's named-producer series, in which each variant is named after the farmer who supplies the key ingredient. The Zerbinati family grow Sentinel watermelons on clay-rich soil in northern Italy, sourced here through a collaboration with Natoora. MOMO brews raw and unfiltered at its New Covent Garden Market site in London. This alcohol-free kombucha brings together a specific cultivar and a close relationship with small-scale producers that runs through the wider named-producer range.
