the bruusta system
how it works
kombucha, brewed on your countertop in six days and poured on tap from your fridge. It works because of two things: The bruusta, your brewing device, a one-time purchase and a bruu base, required for every batch. From there, flavor shots are yours to play with: entirely optional, endlessly mixable. To start brewing, you'll need both a bruusta and a bruu base.
how it works
the perfect brew in 3 simple steps
- 1
prep your brew
add water, drop in your brew pack, and wait 4 days. the bruusta does the rest.
- 2
refrigerate
2 days in the fridge builds natural, refreshing fizz.
- 3
tap & enjoy
pour as much or as little as you want and enjoy fresh kombucha on tap.
the device
designed to brew, carbonate, and pour
the bruusta is a sealed, pressure-controlled vessel that brews, carbonates, and serves your kombucha without ever needing gas canisters or bottling.
a calibrated valve manages pressure safely while preserving natural fizz, and the integrated tap pours with minimal oxygen exposure, keeping every glass fresh until the last.
the bruu base
what makes it kombucha
days 1–4 · on the counter
brewing
everything the ferment needs is already in the base: tea, sugar, and a living culture.
the yeast we add gets to work on the sugars first, producing alcohol and CO₂. the bacteria follow, turning that alcohol into organic acids, the source of kombucha's tang, and what makes it gut-friendly.
days 5–6 · in the fridge
conditioning
once your brew hits the fridge, fermentation slows down.
this is the ‘conditioning’ phase, where the natural carbonation reabsorbs into the liquid, smoothing out the fizz. Flavours mellow and settle, giving you a crisp, clean pour that’s delicious straight from the tap. The cooler temperature also helps stabilise the brew, lock in flavor and preserve freshness.
the science
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 flavor shots
one brew, endless possibilities
add a splash
mix 2–3 teaspoons of flavor shot into your glass.
tap your original bruu
top up with fresh kombucha on tap.
gently stir
enjoy your custom-flavored kombucha, made your way.
