Kefir water satisfies the rising demand for crisp, tangy beverages that do more than taste good, and M&S' new Water Kefir beverages answer the call as lightly fermented sparkling drinks that pair real gut health benefits with guilt-free refreshment. For those who appreciate tart-sweet pairings, there's Water Kefir Strawberry and Rhubarb, while Water Kefir Melon Punch goes big on juicy, uplifting flavor. Both options combine water kefir cultures with fruit juices and fizz for a convenient upgrade on plain water, sparkling water or juice.

Without sacrificing the clean refreshment they crave, people are turning to drinks like water kefir, especially as an alternative to kombucha because it sidesteps the polarizing vinegary tang and heavy acidity.
