Stamina Conqueror in the smaller 350ml bottle is the single-serving pour of Fieldsway's Caribbean stamina tonic — same bold herbal flavour and root-deep character as the family bottle, in a more manageable size. Drunk in small measures, chilled, the traditional way Caribbean tonics have always been taken. The 350ml bottle suits a single drinker or anyone trying Stamina Conqueror for the first time. Fieldsway sits alongside Baba Roots, Magnum, and the other familiar Caribbean tonic brands on UK grocery shelves.
