The fermenter, also known as the keg is a container that has an airlock at the top. It has a secondary airlock, typically made of plastic or rubber, on the bottom for adding oxygen to the beer's interior. This small vessel has the job of holding the liquid from the yeast at the start of the fermentation process. Once the yeast has converted the sugars found in the wort into alcohol, it will begin to ferment, which converts the ethanol into carbon dioxide and CO2, also known as wine.
An important aspect of the fermenter is the secondary airlock. A secondary airlock helps to preserve the flavor of the beverage and release oxygen in the fermenting process, allowing the beer to have a fuller, fuller taste. Not only does the airlock release oxygen, but it also allows the beer to age, allowing the yeast to grow and mature to full flavor. The secondary airlock provides both a longer life and fuller taste than a plastic airlock.
The Stainless Steel Fermenter, which comes in a variety of styles, is considering a functional product in a bar. Some of the more modern stainless steel fermenters are easy to clean and can accommodate between three and five gallons of fermenting. The newer models feature a charcoal filter or natural stone filter for easy filtering of debris and sediment. Some of the older models do not offer this additional filtering. They may, however, provide extra insulation against freezing temperatures, which prevents the beer from chilling. These newer models are also able to hold carbonated beverages without any problem, whereas in some older models carbonation may not be retained. When choosing a fermenter you must consider the amount of time that you plan to spend in your home, and what size of fermentation you plan to make.
