Draft Beer Concepts

Unread postby Luis Coentrao » Tue Feb 24, 2015 5:53 pm

Recently I faced with 2 opposite concepts of "How to serve draft beer": Germany versus USA
(at least in my point of view)

I invite you to read the following documents:
http://www.draughtquality.org/wp-conten ... _Final.pdf (see page 41)
http://www.erdinger.de/en/component/doc ... t-ewb.html (see page 3)
http://www.erdinger.de/en/erdinger-weis ... rving.html (Calculator)

And to see the video:

In summary,
- The Germans recommend that the pressure applied to the Keg should be the carbonation pressure + the pressure required to overcome the resistance of the draught system (line, heigth, shank);
- The Americans recommend that the pressure applied to the Keg (carbonation pressure) must equal the total resistance of the draught system.

IMO:
- I think the USA's recommendation is intelligible: we need restriction in the draught system to counterbalance the pressure inside the Keg, to get a good pour (~8 seconds per pint) and to maintain carbonation.
- I don't capture the German's way: they adjust the Keg's pressure depending on the draught system resistance... :? The longer the lines, the higher the pressure set in the manometer will be :shock: the aim is to get the same pressure as the Keg in the faucet; the flow is controled by the compensator in the faucet.

Anyone here with a different understanding?

Thy are both wrong. :D
Kegs and over carbonated beer is evil, casks rule and beer is pulled not pushed from the cask :)
Long live real ale!
