Frequently Asked Questions

What is the best fermenter for beginners?

The Catalyst Fermentation System is a great choice for beginners thanks to its all-in-one design that simplifies transfers and reduces the risk of contamination.

How do I control fermentation temperature?

Use a WiFi Temperature Controller or a Kombucha Heat Wrap to maintain steady temps for consistent fermentation.

Why use an airlock on my fermenter?

An airlock allows CO₂ to escape without letting oxygen or contaminants in, helping protect your brew during fermentation.

How do I know when fermentation is complete?

Measure the specific gravity using a hydrometer on consecutive days; if it remains steady, fermentation is done.

Can I reuse fermentation equipment?

Yes — thoroughly clean and sanitize your equipment after each use with One Step No Rinse Cleanser to prevent off-flavors or infection.
