It is fitted with a fermentation lock. A fermentation lock or fermentation airlock is a device used in beer brewing and wine making that allows carbon dioxide released during fermentation to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation. There are two main designs for the fermentation lock.
A picture of a DIY fermentation vessel with integrated fermentation lock. Kilju (Finnish pronunciation:) is the Finnish word for a mead-like homemade alcoholic beverage made from a source of carbohydrates (such as cane sugar or honey), yeast, and water, making it both affordable and cheap to produce.
A fermentation crock, with ceramic weights. A fermentation crock, also known as a gärtopf crock or Harsch crock, is a crock for fermentation.It has a gutter in the rim which is then filled with water so that when the top is put on an airlock is created, which prevents the food within from spoiling due to the development of surface molds.
An airlock on board the Space Shuttle. An airlock [a] is a room or compartment which permits passage between environments of differing atmospheric pressure or composition, while minimizing the changing of pressure or composition between the differing environments.
An ordinary glovebox, showing the two gloves for manipulation, with airlock on the right. The most straightforward type of air-free technique is the use of a glovebox.A "glove bag" uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed.

Primary fermentation in homebrewing takes place in large glass or plastic carboys or food-grade plastic buckets, nearly always sealed. [60] When sealed, the fermenter is stoppered with a fermentation lock , which allows the carbon dioxide gas produced to vent, while preventing other gasses and particles from entering.
Secondary fermentation is a process commonly associated with winemaking, [1] which entails a second period of fermentation in a different vessel than the one used to start the fermentation process. An example of this would be starting fermentation in a carboy or stainless steel tank and then moving it over to oak barrels. Rather than being a ...
