Everyone imagines that kefir is reserved for naturopaths and people who have a dehydrator in their kitchen. The reality? It’s one of the simplest preparations you can make at home. Ten minutes of work, three days of patience, and you get a one-liter bottle of homemade sparkling drink that costs almost nothing.

In your glass, orange kefir has this light amber color, slightly cloudy, like home-pressed apple juice. The bubbles rise gently — fine, steady, nothing like the big bubbles of industrial sparkling water. Something more discreet, more alive. The smell is surprising at first: slightly tangy, lemony, with a yeasty undertone that vaguely recalls a brioche coming out of the oven. And the first sip is fresh, a bit tingly on the tongue, with the orange coming through cleanly without being overly sweet.
