What is a brewing vessel?

A brewing vessel is a container in which beer or other fermented beverages are produced. Brewing vessels are typically made of stainless steel, copper, or aluminum, and they come in a variety of shapes and sizes. The most common type of brewing vessel is the brew kettle, which is used to boil the wort (the liquid that is fermented to produce beer). Other types of brewing vessels include the mash tun, which is used to convert the grain into wort, and the fermenter, which is used to ferment the wort into beer.
