Pink gin has a sweet but tart flavour because it's made with strawberry, redcurrant and raspberries.
Pink gin is made just like any other normal gin, through a distillation process. The flavours and any added colourings are added during this process to infuse the gin.
Pink gin was the creation of the British Royal Navy in the 1800s. Angostura bitters were widely used by sailors as a remedy for sea sickness.
