Lo Bros Kombucha Purple Grape is one of the brand's range of kombucha flavours, brewed from a blend of black and green tea over 21 days in small batches. Each bottle has over 100 million live cultures of Bacillus coagulans added after fermentation, retained through a filtration process that removes the yeast while keeping the bacteria alive. This process also makes the product shelf-stable without refrigeration. The brand positions this as a non-alcoholic, better-for-you take on a classic grape-flavoured soda.
