GUTsy Captain Kombucha Zero - Pomegranate is part of the brand's Zero sub-range, a non-alcoholic kombucha line formulated without sugar or calories. Like its standard-range counterpart, it combines natural pomegranate flavouring with organic carrot concentrate, an unusual ingredient pairing that contributes to the drink's colour alongside the fermented green tea base. The Zero sub-range was a distinct product launch, offering the authentic fermented character of the standard range without residual sugars.
