GUTsy Captain Kombucha Zero - Raspberry is part of the brand's Zero sub-range, a non-alcoholic kombucha line formulated without sugar or calories. It is the zero-sugar counterpart to the standard Raspberry kombucha in the brand's permanent range, with the Zero formulation removing the residual sugars present in the standard version while retaining the raspberry flavouring. The Zero sub-range spans a number of flavoured variants alongside the unflavoured Zero - Original.
