The water filled fermentation tube is used in the fermentation process to protect the contents of the setting from oxygen enrichment while allowing the regular release of carbon dioxide generated during the process.
Thanks to the moving water column, we can observe the changing intensity of the fermentation process from the turbulent stage (intense bubbling) to stationary. It is natural to evaporate the water, so remember to fill it into the tube. Otherwise, there may be too much oxygen enrichment of the liquid, which oxidizes the resulting ethanol to acetic acid. This unfavorable process can also be caused by fruit flies entering the shell. If the water level in the tube is limited, we can fill it with less evaporating oily liquid.
