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.

  • Bruusta kombucha brewing machine designed for easy home fermentation, carbonation and dispensing

    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.
