King of Kefir was founded in Dublin in 2014 by Gerry Scullion, with a simple idea: to create a light, elegant fermented drink that’s good for both your gut and the planet.
As Ireland’s first dedicated water kefir brewery, we pioneered an alternative to sugary soft drinks and kombucha — a sparkling probiotic drink made with organic kefir cultures, carefully chosen botanicals, and no artificial additives.
Mission Statement
To craft gut-friendly drinks that celebrate real fermentation, natural ingredients, and Irish innovation — making water kefir accessible to everyone who values health, flavour, and sustainability.
Keith set up a studio in the same building as Gerry, the Chocolate Factory Arts Centre, to make hand-crafted artisan lighting in 2014. When Gerry needed help bottling one of his early batches of lemongrass and ginger in his development kitchen, Keith stepped up. As the production of King of Kefir drinks grew, Keith worked more and more with Gerry on the filling operations and contributed immensely to the successful production of the drinks. He is now a partner in the business.
