How Do Draught/Draft Beer Systems Work - Beer Taps Explained

- A bar serving a cool beer from the tap (faucet) has, often in the cellar, underneath the bar, or in another room, a set up that looks a bit like this. Sometimes the entire setup fits within what's called a kegerator, or parts of it are cooled (not frozen) to make sure the beer you're being served is at an optimal temperature.
To set up a draught beer system there are a couple of variables to keep in mind: The distance your beer has to travel from the keg to the tap, the type of beer you're serving, the beer's ideal serving temperature and what type of coupler the keg it will be delivered in is fitted with.
Depending on local laws beer lines can be made from stainles steel, copper or food-grade PVC. Either way, these need to be cleaned regularly.
Couplers allow gas to enter the keg while, at the same time, allow beer to flow up and out of it. The spear, inside the keg, runs down to the bottom as far as it can, in order to enable as much beer as possible to flow out of the keg.
Many beers (such as pilsners) require carbonation. That is why CO2 is often used. Other beers, such as dry stouts, use nitrogen instead. Nitrogen, however, is used under higher pressures. Therefor a nitrogenized beer setup requires nitrogen-specific regulators and possibly other hardware.
In the UK beer engines and flat, "real" ales are more popular. Here the kegs are called casks and no gasses are used. Instead, the ale casks are aired and the warm beer is pumped, manually, using the beer engine. How, exactly, is a great topic for another video.

Perfect! I'm going to have to look up what type of connection he's got and then make some sort of chart for the various pressures based on the beer.
Thanks for working hard - don't worry about sub counts, you're amassing an awesome library so that when one of these gets featured somewhere or in someway gets a ton of traffic, people will be able to binge through everything.
Hey David, thank you! That sounds like an interesting side project, too! There are loads of beers, though, I do believe the pressure has more to do with the distance to the tap and wether it's a carbonized or nitrogenized beer, than if it's a bock or pilsner. But the brewer can probably tell you more about the beer they brew.
By the way, could you message me via Twitter again? I never got your message through the About page, apparently the Send Message button here on CZcams doesn't work (for me), and I still have that Amazon Gift Card with your name on it ;)
These videos are brilliant. You deserve so many more subs
+DavidsInferno Thanks! I agree ;)
Can you post a video explaining how beer engines work.
fantastic job
very informative, thanks!
Excelent video!! Do you mind sharing some information about balancing a draft system that includes a chiller and a trunk line? Especially I would like to know how long is the coil inside those beer chillers. Thanks in advance
Excellent Video!
Do you know how long can the beer travel from the cold room to the taps without any kind of extra cooling system?
Nice, now the question is, can empty Kegs be refilled with water?
How to does a hand held tap work,usually used for sodas and tonic water
The bartender/barsteward pulls a handle at his tap. OK, but exactly what does that handle do? Does it simply allow the liquid beer to move out through a valve, like a regular faucet? Or rather, does it allow pressurized gas into the keg, which then pushes the beer out of the keg and into the glass? Something else?
What type of gas is used for beer ?
Sir its been 5 years please share with us how beer engines work
Is it possible to install a system for fruit punch? Iâm possibly 12
Beer engines!!!!!!
That video is actually in the works. Albeit very... very slowly due to time constraints.
