Webinar Summary

Craft beer seeing only percentage level growth year over year, many craft brewers are diversifying their product lines into various alternative beverages including hard and NA kombucha. The ASBC Alternative Beverage Taskforce aspires to support craft brewers as they enter these new alternative beverage spaces. Hard and non-alcoholic Kombucha represents an enormous and rapidly growing market segment in the US (from $1.8 Billion in 2020 to over $4 Billion in 2021), drawing in craft breweries to kombucha production. However, kombucha production differs significantly from beer production, involving a diversity of yeast and bacteria (including some potent beer spoilage organisms) with anaerobic and aerobic stages.  This webinar will help attendees understand how these diverse microbes impact the kombucha production process and final product, as well as how to build​ your own kombucha Symbiotic Culture of Bacteria and Yeast (SCOBY) can give you control.


  • Introduce research profiling what the typical kombucha Symbiotic Culture of Bacteria and Yeast (SCOBY) looks like in terms of which yeast and bacteria are present and when/where.
  • Learn what organisms you need if you want a SCOBY pellicle to form vs. want to avoid forming a SCOBY pellicle mass.
  • Understand how the very specific conditions of a fermentation system (tea, sugar source, oxygen availability, temperature) will affect what organisms will become dominant.
  • Be able to explain how to isolate and incorporate specific bacteria and yeast into your custom SCOBY to control the production process and final product characteristics.​
