Maison Lagneaux creates their "micro-brewery" in Lasne, where they produce their fruit kefir and a superb craft beer. Maison Lagneaux needs to make the product from A to Z because there lies the secret of any drink of character. Kefir Eau Vertueuse is a fermented drink, healthy and sugar free, alcohol free, not filtered and not pasteurized, slightly sparkling, rich in probiotics, vitamins and minerals. Thanks to its stable and sugar-free formula, our kefirs can be stored at room temperature. It is the perfect alternative to sodas with many health benefits. It is what we call a "super-drink.
