GUTsy Captain Kombucha Original is the unflavoured entry in a range that extends to flavoured variants and a Zero sugar sub-line. The brand launched in 2016 under the name Captain Kombucha before rebranding to GUTsy Captain in 2019, and has since grown to distribution across more than 35 countries. The Original is an alcohol-free kombucha fermented in Portugal, forming the base of the lineup.
