A cooler with a cooling coil or cold plate and faucets to chill the beer at the point of dispense.
A direct-draw, self-contained refrigerator where the number of kegs accommodated varies based on box and keg size.
A draught beer system that has a short jumper connection from the keg to the faucet.
A draught beer system over 50 feet long that uses barrier tubing in a refrigerated bundle that typically requires a mixed gas to avoid overcarbonation.
A mineral deposit of calcium oxalate that forms slowly on a surface from beer and is very difficult to remove.
A draught system that uses a secondary refrigeration unit (power pack or glycol chiller) to maintain draught beer at the proper temperature all the way from the walk-in cooler to the faucet.
Cask ale, or real ale, is beer that has gone through a secondary fermentation in the vessel from which it is dispensed. The carbonation occurs naturally from the fermentation process. Cask ale is served directly from the spigot under gravity; pumped from a beer engine.
The mount on the bar that holds the faucets and is cooled to maintain beer temperature up to the point of dispense.
The dispensing end of the draught beer system that controls the flow of beer.
The connecting piece that goes through the cold box wall or tower and connects the tubing and tail piece to the tap. It also can help provide system pressure reduction.
The flexible piece of vinyl tubing used between the keg and draught beer system that should be replaced annually.
The tubing that is used to transport the beer from the keg to the faucet. It is also used to control the flow rate of beer by properly selecting the material and size of the beer line.
A mechanical pump that is generally driven by compressed air or CO2 that can move beer great distances without changing the dissolved gases.
Foam on beer detector. A device that stops the flow of beer when the keg is empty before the beer line is filled with foam.
The connector from the draught system to the keg.
The modern style of keg coupler. It is available in several versions to fit specific styles of keg valves produced in Europe and the U.S.
A repurposed soda keg that is easily refillable and is often used for cocktails on draft. Utilizes ball lock couplers and connectors.
These vessels hold beer that undergo secondary fermentation in order to naturally carbonate the beer. No additional gas is used to dispense. Pairs with the beer engine for proper dispense.
A Beer Engine, also known as a hand pump, is a uniquely British dispensing device that is specifically appropriate for traditional cask-conditioned ales.
Ensuring that the applied pressure matches the system requirements so that the beer dispenses at the optimum rate of about 2 fluid ounces per second, or 1 gallon per minute, while maintaining brewery specified carbonation level.
A measure of the pressure drop across a component or over a length of tubing at the optimum beer flow rate.
The change in height from the keg to the faucet that is a component of system balance.
Choker line, also known as restriction tubing, is a section of 3/16″ internal diameter (ID) vinyl or flexible tubing of variable length installed at the tower end of a long-draw draught system.
The connectors that allow a piece of tubing to be attached to a piece of equipment.
Trunk line is the main section of tubing, usually barrier tubing, that runs the length of the system from the wall bracket in the cooler to the tower
Powdered Brewery Wash is a patented buffered alkali cleaner that has been proven to be more than an effective substitute for caustic soda cleaners.
A high pH chemical commonly blended into draught line cleaning solutions. Caustic will react with organic deposits in the draught beer line. Very effective, but also very dangerous. Commonly used in oven cleaners.
Although several blends of acid cleaners are recommended to assist in beer stone and water stone removal, some acids react with system components. Phosphoric acid-based blends are the only ones safe on all materials.
The change in height from the keg to the faucet that is a component of system balance.
A mineral deposit of calcium oxalate that forms slowly on a surface from beer and is very difficult to remove.
A calcium carbonate mineral deposit that forms from water and can be removed with acid.
Refillable pressurized metal cylinder that holds compressed gas for beverage dispense. Come in 5#, 20# and 50# sizes.
Carbon Dioxide is the main gas used for the dispense of beer, cider and kombucha.
Diatomic nitrogen (N2 ) is an inert gas that is used in a draught system to help propel beer a long distance. Specific beer styles uses nitrogen to enhance its head and mouthfeel of the beer.
This is a 75/25 blend of N2 and CO2 and is used to push “nitro” products like Guinness.
The tubing that is used to bring CO2 and other gases into the draught system. Vinyl gas line is used for pressures less than 50 psi; higher pressure will use braided gas line.
A gas control valve that delivers a set gas pressure regardless of tank pressure. There may be a primary regulator on the gas source and a secondary regulator at the gas connection for each keg.
Gauge pressure is the pressure of the dispensing gas applied to beer beyond the local atmospheric pressure level, usually given as pounds per square inch, gauge (psig).
These regulators are designed for being used with a multiple keg setup since they reduce the pressure from the primary regulator, which is then distributed to each individual keg in the system.
Manifolds allow you to have one CO2 tank with multiple lines. Each line can be turned off individually without affecting flow to other kegs.
This is the setting on the regulator that you use when taking into consideration the CO2 volumes of the beer, ABV, temperature, and altitude to calculate the pressure needed to maintain correct carbonation in the keg.
Also known as a Thomas Valve, this is the valve that allows CO2 to flow into the keg but prevents beer from backing up into the gas line.
A beer gas blender is a piece of equipment that blends gas together for a beer system. It does this by taking in C02 and Nitrogen through its inputs. Then blends the gas to the right mix.
A system designed to separate nitrogen from compressed air, typically by membrane. Nitrogen used for beer dispense in a mixed gas application must be >99% pure.
The concentration of CO2 in beer expressed as volumes of gas at standard conditions per volume of beer.
