A little family business

Happy Kombucha started in 2009 with a hobby, a jar on the kitchen counter and a fascination with fermentation. More than 15 years later, we're still a small family team, and every culture, from kombucha SCOBYs to milk and water kefir grains, is still grown by hand at HappyHQ, then picked, packed and sent fresh to you.

Every order comes with full instructions, and we're always here to help. If your culture doesn't work, we'll help you get it going or replace it free of charge.
