how our kombucha comes to life

  • the culture wakes up

    At the heart of every kombucha brew is a scoby - a living culture of bacteria and yeast that kicks off fermentation. when you add our bruu base to your bruusta, this culture wakes up and gets to work.

  • fermentation begins

    The yeast we add starts by feeding on sugar, creating tiny amounts of alcohol and CO₂, while the bacteria convert that alcohol into gut-friendly organic acids.

  • real fermentation at home

    This is the same biological process used in traditional home brewing, just made simpler and more consistent with our long-fermented base. no corners cut, no shortcuts, just real fermentation, happening in your home.

the foundation

what goes into every bruu base

  • our tea leaves

    Organic green sencha tea from China, blended with bold black tea from Sri Lanka, India and Mozambique, a light, grassy brightness with warmth and depth. the perfect foundation for fermentation.

  • our living culture

    At the heart of every batch is the SCOBY, a symbiotic culture of bacteria and yeast, ours comes from a lineage with long heritage. It’s what transforms our tea base into real kombucha.

  • our fuel

    Organic cane sugar, sourced for purity, not for sweetness, but as the fuel that powers fermentation. Paired with a specialist brewing yeast for a smooth, steady finish.
