Frequently Asked Questions
A very simple explanation, provided by Science Clarified is:
The chemical reaction that occurs in fermentation can be described quite easily. Starch is converted to simple sugars such as sucrose and glucose. Those sugars are then converted to alcohol (ethyl alcohol) and carbon dioxide.
Carbon dioxide creates the “fizz” in fermented foods, in addition to forcing oxygen up and out the airlock, creating healthy anaerobic conditions.
Creating kefir in a Pickl-It results in a carbonated, “champagne” style –
“The CO2 gas produced leads to fine flake” coagulation formation and also imparts a sparkling mouth feel to kefir. The presence of the gas bubbles in the drink has prompted some to refer to kefir as the champaign of fermented milk drinks.” Handbook of Fermented Functional Foods, p. 90
Excess carbon dioxide is a problem in some closed-fermentation systems, if it doesn’t have a means to escape, leading to possible explosions of the vessel. The Pickl-It airlock manages the carbon dioxide content, keeping it at a safe, even level.

Wow!! Thanks for your helpful guidance as we switched our water kefir fermentation over to the Pickl-It system. We’ve been making water kefir for over a year, but it has always been open to the air with just a mesh covering. A couple of days ago our Christmas 3 – 3 Bundle came in and we set up the water kefir grains in a 1 L. It was time to harvest (& taste!!) this morning and IT IS SOOOOO GOOD!!!! There are none of the vinegary notes that were present in our past batches. It’s fully done – which I judge by the fact that it’s only very very slightly sweet, and the carbonation is good (on the subtle side instead of tickling your nose). It’s perfection! The flavor is very pleasing and refreshing. There’s no going back now : ) This is an easy breezy way to ferment excellent water kefir for sure!
