Brewing Equipment

Barrel
A measurement or container of beer, which equals 31 gallons.

Brew pot/Kettle
The vessel used to boil wort.

Bright Beer Tank
A vessel used as a holding tank just prior to bottling or kegging beer. Beer goes into the bright beer tank just following filtration (if filtering is done) and beer may be carbonated in it.

Carboy
A glass or plastic vessel used in fermenting beverages such as wine, mead, and beer. Usually fitted with a rubber stopper and a fermentation lock to prevent bacteria and oxygen from entering during the fermentation process. Typical size for homebrewing is 23 litres.

Cask
A closed, barrel-shaped vessel used for fermenting and serving beer. They used to be made of wood, but now most are made of stainless steel or aluminum. They are used for cask-conditioned ales, which need to be vented intermittently while they naturally carbonate.

Conditioning Tank
The vessel in which beer is placed following primary fermentation where it matures, clarifies and becomes carbonated. Also called secondary fermentation tank.

Exchanger
Equipment usually used after the boil for cooling wort quickly before yeast can be pitched in the wort.

Firkin
A measurement or container of beer, which equals one quarter of a barrel (40.9 liters).

Hand Pump
A hand-pump device that draws draft beer to the taphead. It allows cask-conditioned ale to be served without the use of pressurized carbon dioxide to push it up to the taphead.

Hydrometer
(1) - A device that measures specific gravity (SG) of a liquid. Hydrometers are usually calibrated for measurements at 60°F. If what you are measuring is not at this temperature, you should use a hydrometer correction table. Approximately the correction amount is (Temperature-1.8)x.03 (e.g. (77°F-1.8) x .03 = 2.2 take the FG and add 2.2 to get the calibrated SG).
(2) - An instrument that measures the amount of fermentation in beer. The hydrometer reading can also indicate the percentage of alcohol in beer. 

Lauter Tun
The vessel in which mashed grain is sparged (lautered). Sometimes referred to mash-lauter tun because usually mashing and sparging occur in the same vessel.

Liquor Tank
The vessel in which water for brewing is stored. It may store either hot or cold water. Serving Tank
The vessel from which beer is served.

Mash Tun
A copper or stainless steel vessel used for mashing the grist and water. Literally, tun is "tub" in German.
