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.
Did you know...
900 AD: Western Europe, late-comers to the many medicinal and culinary uses for dill, obtain theirs from Sumatra. Centuries before, Romans considered dill to be good luck, while ancient Greeks considered it to be a sign of wealth. The word “dill” is from the Norse “dilla” which means to “sooth or lull”.
You know you talk about fermenting too much when…
Your three-year-old is observed pushing his bath toys under the water while saying, “You must go under the brine to ferment. Then I will have sauerkraut toys.”
