A fermenter, with regard to brewing beer, is a vessel that brewers use to convert wort into alcohol. Fermenters are typically made from stainless steel, glass, or plastic. Wort is the mixture of water and grains that has been boiled by the brewer. After boiling for an hour or so, the wort needs to be cooled before it can be put into the fermenter. The first step in converting wort into alcohol is to cool it down with water so there isn't any heat shock when adding it to the fermenter.
