All pre-orders are final and non-cancelable. The funds collected during this phase are critical in helping us scale up production and bring KOMBU to life.
We understand that, on occasion, backers may request a cancellation. However, it's important to note that by that stage, a substantial portion of each pre-order is allocated to unavoidable costs such as platform commissions, credit card processing fees, marketing, agency support, and partner collaborations. After covering these necessary expenses—excluding manufacturing—we often retain less than 50% of the original pledge.
While pre-orders are generally non-refundable, in rare and exceptional cases where we may choose to offer a refund, it would be limited to 50% of the original amount.
We’re committed to being transparent and fair throughout the process. Once you receive your KOMBU device, you will be fully covered under our warranty terms if there is any issue related to damage or manufacturer defects.
Thank you for your support and understanding as we work to bring this product to your home.
Real Kombucha. Made Easy.
Brewing great booch with KOMBU is easy and affordable, making kombucha's health benefits accessible to everyone.
Bottled Up
Glass Bottle
The secondary fermentation process in your bottles creates natural carbonation (that delightful fizz!) when sugar or juice is added. Our glass bottles are designed to withstand high-pressure.
Carbonation Cap
Our bottle caps feature a Pressure Relief Valve (PRV) built right into the caps. This feature provides an extra layer of safety by releasing pressure automatically if it reaches 65 psi.
PRV
We’ve carefully integrated the PRV into the cap’s design to maintain our bottle’s original aesthetic while adding this essential functionality. The cap looks just like a regular bottle cap and is fully removable for easy cleaning.
Heat
Just
Kombucha ferments best in a consistently warm environment. The Fermenstation utilizes a low heating, temperature-controlled system to maintain steady warmth for the desired amount of days.
-
An ambient air sensor controls the heating pads to maintain that perfect goldilocks warmth (24-28C / 75-82F). Each side (F1/F2) operates its heating and timer functions separately. Once the timer finishes, the heating stops and the system enters standby mode.
