Introducing
The modern kombucha brewer
A better way to brew your booch. Bring kombucha into the 21st century with an efficient, compact, and connected device.
A better way to brew
Making kombucha wasn't always this easy.
before
Home-brewing kombucha is a complicated mess.
No current solution. Inconsistent results. Messy setup.
after
KOMBU makes it simple.
A simple, beautiful brewing experience designed to fit every kitchen.
Smooth
Let’s get things bubbling with dual-stage fermentation. Ferment the first stage (F1) for plain Kombucha, then ferment the second stage (F2) for flavor and carbonation.
Iconic Design
This countertop hero sports a slim and compact footprint, plus a sleek design that’ll look good wherever you set it.
Consistent
Dual-stage fermentation using a low heating, temperature-controlled system with minimal analog buttons.
Connected
Stay connected by using the IoT mobile app to control the device, like setting timers, and monitoring the temperature.
how to
Brew Kombucha
Make plain kombucha (F1)
Add sweet tea and a SCOBY to brew an always-ready base. Pour what you need, then top it back up to keep the cycle going. 7 to 10 days.
Flavor your kombucha (F2)
Bottle your base with fruit, juice, spices, or extracts to flavor and carbonate. 3 to 5 days.
Priced In
Brew for cents, not dollars.
Brew organic kombucha at home for about $0.39 per 500ml. If you drink booch daily, KOMBU pays for itself in about 4 months.
Do yourself a flavor.
Explore recipes across Classics, Culinary, and Adventurous. Start familiar, go deeper, and find your signature pour.
Science Support
The best way to support the gut microbiome is to consume 1-4 servings of low-sugar fermented food per day.
Fermented sugar-based products... are like winning the lottery when it comes to gut and brain health.
"The benefits of probiotics include improved immune system, decreased inflammation, decreased cholesterol, increased nutrient absorption..."
Incorporating fermented foods into your diet can significantly enhance your gut microbiome and help reduce inflammation.
