GUTsy Captain Kombucha Summer Peach is a limited-edition alcohol-free kombucha and one of a summer-flavour variant pair in the brand's range. Natural peach flavouring is added post-fermentation, and the brand does not use artificial flavours or sweeteners in its formulations. The Summer series sits outside the brand's core permanent range and the separately named Zero sub-range, positioning Summer Peach as a seasonal option alongside Summer Lemonade. Availability may differ from the permanent range as a result of its limited-release status.
