Fermentation tanks, also known as fermentation containers, are used to hold wort and ferment it into beer. Even in the most basic home-based brewery, the fermentation tank is vital. Almost any container that can store liquid can function as a fermenter. Different yeasts can ferment different items in the fermentor. Using brewer’s yeast, the wort may be fermented into beer. This is because yeast transforms sugar into alcohol during the fermentation process of creating beer. In a fermenter, biomass may also be converted into biogas.
