Correct Tap Pressure?

[gravelsanga]

Hi,

Well, my first keg brew has finished carbonating (2 days at 230 kpa)and i'm really happy with the end result but at the recommened pressure of 70 kpa i'm having a hell of a time pouring anything other than a glass of pure foam. I've been mucking around and i pretty much have to drop the pressure on the gauge down to 0 to get a reasonable beer. Is there a reason for this or is there something i've done wrong or need to do?

Thanks for your help.

3 metres of 5mm beer line should slow you pour to a managable speed.

Sounds like it's overcarbonated. Longer beer line will help.

My beer line is 1400 mm long so i'll try a longer one, see what happens. How can you tell if your beer is over carbonated? It doesn't seem to be over bubbly accept for the head.

Thanks for your replys!!

2m is better. Have a read of the kegging wikki.

Before pouring your first beer, remove all head pressure in the keg. Turn off the gas at the cylinder and then release the relief valve till it stops hissing. Wind the gas reg knob out, turn the gas back on. Turn your beer tap on, wind the gas pressure up slowly till beer starts pouring out the tap (into your waiting jug.). You probably won't need much pressure.

If you still have too much foam after changing the line to a longer length, the beer is probably overcarbonated.

POL,

What happens if you have too long a beer line?

For a highly carbonated lager it needs about 100 kpa to stay carbonated.

5mm beer line has 33kpa of resistance per metre. So if you divide the 100kpa by 33 you get 3. 3 metres of 5mm line for your system to be balanced. You can still pour ales through the longer line but the pour is slower.
