So much empty space on that table

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.

Where can you buy a Fermenter?

Any homebrewing shop worth their wort should be able to supply you with a fermentor. Large scale online brew supply shops like MoreBeer should be able to as well. Then there's always Amazon if you're low on cash and need two-day shipping.
