GUTsy Captain Kombucha Watermelon and Mint sits within the brand's core kombucha range, produced from a base of organic green and black tea rather than a single tea variety. Fermentation runs for 40 days using a SCOBY culture. Despite being a live fermented drink, the product is shelf-stable before opening and requires no refrigeration until after the seal is broken. This variant sits alongside a wide selection of fruit and botanical flavours within the range.
