Fermenting kombucha at home or for your brewery is exciting, but it can be hard work if your setup is wrong. The right fermenter means fewer problems, like mold or leaks. But choosing wrong could mean wasted money or tea. In this guide, we’ll keep it super simple and clear. You’ll see what works, what does not, and how top brewers get tasty, safe, fizzy kombucha, every single time.

Types of Kombucha Fermenters
Some fermenters break. Some let in light and ruin flavor. Others trap dirt or are hard to clean.
Let’s look at the main types:
Type | Pros | Cons | Best For |
---|---|---|---|
Glass Jars | See inside; easy to clean | Breaks easily; lets in light | Beginners |
Stainless Steel | Tough; keeps flavors pure | Harder to see inside | Big batches |
Ceramic Crocks | Keeps cool; old-school style | Heavy; can crack | Traditions |
Continuous Brew | Always ready; saves work | Can be tricky to set up | Busy brewers |
Data highlights: Glass is #1 for home brewers (68% prefer it). Stainless steel is growing for its durability and large size need, especially in North America (55%) .

How to Choose a Kombucha Fermenter
Picking the wrong fermenter might let in germs or break during use.
This could cost you good tea and a sad SCOBY. The wrong gear also makes cleaning hard and messes with taste.
Solution: Pick using this checklist:
- Material: Choose food-safe glass or stainless steel. Avoid plastic!
- Size: 1-gallon fits most. Go bigger for business or big families.
- Lid: Needs a cover—cloth for air, or special lids to keep bugs out.
- Spigots: Great for easy draining, especially in continuous brew systems.
- Budget: Most homebrewers spend $20-$50 (83% of buyers prefer this range)

How to Use Your Fermenter
Good tea means safe practices. Bad practices lead to mold, weak fizz, or vinegar taste.
Step-by-Step Guide:
- Clean All Parts: Use hot water and vinegar. Soap can kill your culture!
- Start Your Brew: Add sweet tea, cooled down, and your starter liquid (already brewed kombucha).
- Add SCOBY: Place gently at the top.
- Ferment: Room temp (75–85°F works best). Use a thermometer or Fermometer for checking.
- Taste Test: 7–14 days is good. Check with a straw—stop when it’s just right!
- Bottling Time: Drain to bottles (spigots help). Use strong bottles for safety.
- Second Ferment: Leave bottles for another 2–4 days for more fizz.
Pro tip: Stainless steel fermenters from expert manufacturers help avoid contamination. They make cleaning easy and consistent, which saves labor and time as your operation scales.
