From Keg to Glass: The Journey of Draught Beer

The beauty of Draught Beer is hard to ignore. The smooth yet bitter taste will give you the perfect high at a nightclub. But the journey from leg to glass is a unique experience that helps in elevating your knowledge of draught beer. Here, you will come to learn about the journey in detail along with the components that help in presenting the final taste.

The coupler, leg, gas, tubing, cooler, and faucet are the major components that form a draught system. It can get complicated from here, but these are the basic components to deal with. These parts function systematically to ensure that the final served beer is carbonated and cold. It should have a foamy head.

The Cooler:

You might have seen that the keg is stuffed into a bucket and then packed up with ice. There is a growing demand for Cask Beer Suppliers for the same. Beer always has to remain cold so that the taste remains intact till the last drop.

  • The cooler prevents the beer from spoilage and warm foamy pours.
  • Some restaurants have walk-in coolers, which will help keep the whole slew of kegs cold at once. This is where the beer journey starts from.

The Main Keg:

Your foamy beer resides inside the keg. Kegs for Draught Beer are now available in different shapes, materials, and sizes. 

  • In general, the beers are usually packaged in 5 gallons, 7.75 gallons, or 15.5 gallon kegs, which are made using stainless steel.
  • You can see a valve located on top, from outside.
  • This hole is where the gas flows in and the beer flows out.
  • Inside these kegs, you will find a long metal tube extended from the valve to the bottom of the vessel.
  • For getting the beer out of the leg, gas pressure is added to the top liquid surface. 
  • It presses the beer right from the bottom up through the metallic tube and out of the main valve.


With the help of an airtight seal, the coupler connects to the leg straight away. The couple’s probe will push directly into the keg valve and serve as a major point in distributing your draught beer. 

  • The coupler houses two ports. One is for attaching the airline and another for attaching the beer line.
  • It is mandatory to check that the lines are linked to the attachments tightly.

Use of Regulator:

The content inside the tank remains under a huge pressure. If you fail to keep the pressure under control, the beer will turn into a foamy mess. 

  • The regulator, at this point, helps in preventing such issues from taking place.
  • It guarantees that the gas performs like it is intended to.

The Gas Cylinder:

As it has been mentioned beforehand, you need gas to help the beer from the leg to run down the faucet. The Cask Beer Suppliers will help you to understand the functionality of a gas cylinder better.

  • Whenever the gas pressure is poured into the leg through the coupler, the beer is forced out into the beer line.
  • Eventually, the beer will come up to the tap, which will help you to pour it in a pint as needed.

The Beer Tower:

The beer lines are housed inside the beer tower. These lines are connected to a draught shank inside the tower, which delivers beer to the faucet. These towers are available in various styles and modified with various draught beer faucets.

The Final Call:

Draft systems need quite some maintenance to ensure that the final beer tastes better all the time. Generally, the restaurants and bars need to clean the raft system once every two weeks and replace the components regularly. Failing to do so can lead to off-flavour beers.
