Guinness mixture

[royce123]

I have a question regarding the Guinness gas mixture. I have a Guinness tap set up at home and recently tapped a new keg of Guinness but I am not getting a good head and very little "cascading effect" when the beer is poured. I have the right mixture but I am using a tank that was filled 3 years ago. Does the gas mixture go flat and would a new tank of gas help?

Do you have a stout faucet? Also if you have a stout faucet are you running enough pressure? Should be pushing the beer with 35psi threw a proper stout faucet. Also with the stout faucet make sure that your restricter plate is in place. It is a small stainless disk in the nozzle that has some tiny holes in it.

I have a set up that came out of a pub in Ireland with a new spout assembly. I will try and up the pressute to 35 PSI and make sure the restrictor plate is not plugged.

Thanks,

Most likely if you have had the keg only on 12psi of beer gas all this time it is going to be really flat. I am not sure that you are going to be able to salvage it. I would put is on 60psi for a few days that might get the nitrogen back into the beer. When I nitrogenate my homebrew I use a carb stone. Nitrogen takes a lot of time to dissolve in the beer otherwise.
