Hi all
Have a question about pouring pressure.
I carbonate my kegs slowly over 7 days at 90kpa at 2 degrees and they come out spot on.
When I pour I use a pressure of about 20kpa. One issue I have is once I pull a couple of beers and let the keg sit for 20-30 mins before pulling another one the first beer pulls really heady due to high pouring pressure. This high pressure comes from what I believe the gas escaping from the beer and pressurising the keg to equal the current carbonation pressure. The second beer pulls fine straight after as the pressure in the keg is released back down to the 20kpa level.
I have a tap on the front of the fridge connected with 1.5 meters of 6mm beer line.
My question is would it help by going to a smaller diameter beer line of a longer length say 5mm at 2 meters to create more resistance and allow a higher pouring pressure to be used.
At the moment I just pull the release valve for a second or two and then pour the beers, but if I forget to pull the release valve the first glass is mostly foam due to pouring too fast.
Any ideas or do I just put up with it or learn to drink a glass every couple of minutes till the kegs gone.
Cheers
