Kult Kefir Water

Kult is a contemporary beverage brand specializing in water kefir, founded in Belgium. The brand focuses on creating fermented, probiotic-rich soft drinks as a healthy alternative to traditional sodas. By using natural fermentation processes with kefir grains, they produce a lightly sparkling drink that is low in sugar and high in beneficial bacteria.

The company maintains its production in Belgium, where it was originally established. As a modern startup in the functional beverage space, it operates independently, focusing on craft-scale production to ensure high quality and authenticity in its fermentation process. The brand is part of a growing movement in European markets toward artisanal, gut-friendly beverages that prioritize natural ingredients over artificial additives.
