Stamina Conqueror in the larger 1.5-litre bottle is a Caribbean herbal tonic drink from Fieldsway — the kind of bold, root-deep tonic Caribbean households have drunk in small measures for generations. The flavour is unmistakably herbal, sweetened and spiced to be drinkable while still carrying the deep botanical character that defines a proper Caribbean stamina drink. Drunk by the small glass, chilled, not by the cupful. The 1.5-litre size is the family or stock-up bottle. Fieldsway is one of the recognised Caribbean tonic-drink brands on UK grocery shelves.
