Should I hear the gas rushing into the Keg?

Hi All,

I’ve been using this forum to help me out with setting up my home bar which is now all up and running. However I do have a problem but it’s a bit complicated to explain…

I’ve had 4 Kegs now of Carling with CO2 which are at room temperature and go through a flash cooler (210 Maxi) , I clean my lines regularly and there’s just over ½ pint from keg to tap. Now the problem is that when I pour the pint and I’m at ¾ you can hear a rush of gas going into the keg. Then when I pour the next pint (straight after the last one) it will give over ½ pint of froth.

The only thing that I can put this down to is the regulator as its 300Bar CO2 4 Bar – 2 displays, but it isn’t a beverage one as I couldn’t source one within my budget. Would this be causing my issues?

Thanks,

Rob

  1. Whoa!! isn’t 300bar something like 4000 psi when all you are looking for is something like 20psi. Yes it is probably your gas reg but I wouldn’t worry about dispensing beer I would be more concerned with staying alive. If the gas pressure is too high the keg will explode there are already documented cases of it killing people. I wouldn’t mess about it isn’t worth it, get a food quality, proper primary and secondary gas reg from Micro-matic or someone like that and enjoy your pint in safety at least. 😮

    or 50/50 mixed gas. Yes for a home bar it would be a better choice, or even 30/70 you will get less fobbing even if the beer does go a little flat to the end of the container, that is if it is being used over a period of time. :-/

  3. Hi all,

    Thanks for the prompt replies!!!

    Maverick – I was looking at those and though I could get away with a cheaper welding one but now that you have said that it’s getting replaced, don’t want the party to be remembered for the wrong reasons!

    Any recommendations of where to get one from? Also what kind would you recommend for running 2 kegs – thinking of having a Carling and Strongbow both on the go!

    Regarding the Gas I heard mixed opinions – what would you recommend to run the 2 kegs together?

    Also if I got a mixed regulator can we also use a standard CO2 bottle on it if desired?

    Cheers

  4. Wouldn’t normally get involved with a discussion with gas however. There are different ones but as Gav says as its a home bar go for mixed gas if you have it hanging around for a while. Have the Taps pouring slowly for less wastage but better still if you can get hold of a dispense engineer he will have it sorted for you in ten minutes. Go for a primary and also a secondary for safety.

    A quick search brought up this.

    No they have different fillings.

    Breweries prefer to use Co2 to keep the original taste. But Co2 causes more problems than it is worth in an outside or home bar (you have to use it quick).

  5. Is it just Carling and Strongbow you are running? If you have a bitter on as well, and just want to use one type of gas, i have found that 30/70 can be used with lager but 60/40 affects the taste and quality of bitters and stouts. Regarding 50/50, i dont know, i have never used it! Strongbow will be the same as the lager, so no problem there!

    As maverick says, use the under-bar flow regulator to slow the lager flow down otherwise it will fob like mad if it is stood for any length of time and even whilst in use it can be a nightmare! Cider tends not to froth too much so you dont need to worry too much about the flow.

    Any problems, again like maverick says, call a technician. Its fairly simple to get right, but as the saying goes, a question is only easy if you know the answers!

  6. Sorry, just read my reply back…. to clarify, 30/70 is predominantly used for bitters, but will work with lager too without affecting it too much, whereas 60/40, which is mainly used in lager, should not really be used with bitters. With normal bitters i.e. John Smiths, the taste and quality will be affected, but with guinness it can actually damage the keg.

    If it is just Strongbow and Carling, my advice would be to get 60/40 which will work well with both, and is only a couple of quid per bottle mre expensive than CO2.

    Hope thats clear! 🙂

    60/40 shouldn’t be used with bitter at the same pressure as lager, the Co2 mix is too high it will be absorbed straight into the liquid and ruin the whole keg it will just become ice cream, it will do the same with Guinness.
