Fermentation tube without sealing rubber

Perform fermentation without foreign bacteria and oxygen with the fermentation tube!

The fermentation tube is placed on the fermentation vessel during the fermentation process and prevents oxygen and air from entering the fermentation vessel. Carbon dioxide, which is produced during fermentation, can still escape. This process prevents the valuable wort from being contaminated by foreign bacteria and causing faulty fermentation. Furthermore, the oxygen in the air can not oxidize the wort to vinegar.

Why do you need a fermentation tube when making beer and wine?

The fermentation tube is almost more important than the fermentation balloon - or your fermentation barrel. Both belong directly together. The fermentation tube ensures that the opening of your fermentation vessel remains tightly closed and that the fermentation gases (carbon dioxide) can escape from the fermentation vessel at the same time. In this way, there is no overpressure. This is not without danger. 

The fermentation tube is also called fermentation bung or fermentation tube. In addition to wine production, it is also used in beer brewing. The fermentation tube has a special shape (curvature). This allows most of the CO2 produced by fermentation to escape

How to fill a fermentation tube?

The fermentation tube is filled to about one third with water. It then has the effect of a one-way street. Excess gas escapes, and at the same time the fermentation tube protects the wine from air infiltration, bacteria and germs. The excess gas is carbon dioxide (CO2) and is a normal byproduct of fermentation. 

What goes into the fermentation tube?

The U-shaped fermentation tube is filled with clear water. Alternatively, you can use a disinfecting solution or high-proof alcohol. Due to the special characteristic shape, a so-called water trap is formed - this water settles in the two bends of the fermentation tube. 

How to use a fermentation tube?

The fermentation tube is filled with liquid - alcohol or water - up to a maximum of half. The liquid remains in the two typical U-shaped bends of the fermentation tube. Important: The liquid evaporates during fermentation and should be checked regularly and refilled if necessary
