Monty Elderflower Social Soda is the only drink in the Monty range, created by Sally Williams after a concussion led her to give up alcohol entirely. Exploring functional ingredients during her recovery, Williams built the brand around adaptogenic mushrooms, and this soda carries three of them: Lion's Mane, Reishi, and Maitake, reflecting a personal discovery of their properties rather than a flavour-trend response. The brand was founded in Hullbridge, Essex.
