Fieldsway Constitution Bitters is a traditional Caribbean herbal tonic made with a blend of botanicals — the kind of bittersweet roots drink Caribbean households have drunk for generations as part of daily wellbeing routines. The flavour is deep and unapologetically herbal, with the dark bittersweet character that defines a proper constitution bitters. Drunk in small measures, the way Caribbean tonics have always been taken — neat, in shot-glass pours, chilled. The 1.5-litre bottle is the family size. Fieldsway is a familiar Caribbean tonic brand whose bottles sit alongside Baba Roots and Magnum on UK Caribbean grocery shelves.
