About Kai

Taiwan's Terroir

About Kai

Brewed With Care

Kai has been Taiwan's craft kombucha pioneer since 2019 — North American fermentation methods combined with local ingredients. We believe a drink can be more than a sensory experience: it can extend care for your body and the planet. When customers tell us 'this is the best kombucha I've ever had,' every effort is worth it.

About "Kai"

Kai is the brand Cindy & Ross built together. The name comes from the Chinese character 開 (kai) — to open. Open your appetite, open your mind, open a bottle and share it with friends. The logo draws from the Pangu creation myth: strength and creativity. Fermentation is one of nature's most magical processes — we treat it accordingly.
