PKW BoochMaster KB-135 Kombucha Brewery is the world’s first expandable professional brewing system engineered specifically for kombucha brewing. It is the culmination of a) deep research into the requirements of small, local Kombucha craft brewers and b) our experience producing hundreds of brewhouses for the commercial craft beer industry since 2011.

PKW’s large brewing systems have become the industry standard, and they are used to innovate recipes and deliver repeatable results for award-winning breweries, large and small, worldwide. Now we’re using that experience to bring efficient, effective kombucha brewing to thousands of boutique kombucha breweries at a never before seen low cost.
