  • Acceleration: Ferment your product for as little time as you want, 1, 2 or 3 days, then add our Perfected Kombucha Culture to get the acidity levels of your choice.

  • Formulation: Using the Perfected Kombucha Culture to bypass the fermentation on your side. Essentially, using it this way you won’t need to ferment your product, we will do it for you. As a result you will have a kombucha with less than 0.1% alcohol and very stable. Also, you can use any type of sugar and even stevia. Finally, this is the best solution if you want to produce your kombucha with a co-packer.

Business Consulting

Lets be honest, the road to "success" is unclear and means something different to every business, brand or individual. This is true in the Kombucha community where new brands are popping up everyday, each with their own ideas of what Kombucha "is" or "isn't", and their own idea of how they define themselves. Some want to create the best niche artisan craft kombucha and other want to be the Brew Dog of the Kombucha world. Each of these are equally correct in their thoughts and ambitions.

We believe at every stage of business growth and development (large or small) clear focus will drive your success. Focused vision, strategy, products, market, leadership, delivery ....this list goes on.
