Default Bought a KEY KEG. Help..Pours constant foam.

I'm in Canada and I bought a key keg of "Bad attitude Hobo IPA" from Sweden. Great beer by the way, kind of like the red laginitas with a slightly different character.

I bought it 4 days ago and the thing pours 100% foam. I have had it in my keg bridge at cool temps, 4-6 degrees Celsius.

On the website it says key kegs require higher PSI to pour so I set it to 20psi and its still foamy. Med carb was 15-20 high carb was 20-25 on the website.

Anyone have experience with these key kegs? I was thinking let it sit for a week and that maybe these key kegs dont handle being moved around as well..

How long is the beer line from keg to tap? 10feet or more?

I believe Raouliii is on the right track. Serving at 20, even 15 psi with five feet of beer line just asks for foam. The diameter and length of the beer line increase the resistance and I've never understood the why.. but longer beer lines, more resistance usually equals less foam.

Not exactly familiar with a key keg. I would say set the psi to the appropriate carb level for style, around 12. Vent and vent again...as the keg is over carbed now. 10ft lines will also help.

Hi

Just to post the entire list:

You could go up to as much as 20 feet of 3/16" beer line.

1/4" beer line would be longer still...

Stuff like Tee's or couplings in the line aren't a real good idea

Be sure that the keg *really* is at 2 to 4C. It's easy to measure one place and have stuff warmer somewhere else.

Let it sit for at least three days after moving it around or changing things.

No, I don't think any of that is likely the issue, but there's the whole list.

Bob

I have Corney kegs and sanky kegs. Key kegs are entirely different and do not follow conventional rules. The Co2 doesn't even come in contact with the beer ever. Co2 compresses in the outer liner between the housing and the bag. The beer is not over carbed unless it was over carbed before I got it. The 15-20 psi was from the manufacturer website, it also stated low psi 5ish would make foam and not pour right.

I appreciate the comments and support, just hoping to hear from someone with key keg experience due to its differences over any common keg type.

I dont have tee's or couplers, I let it sit for 5 days now, I run a commercial beer fridge, I have 1/4 lines IIRC. Normally I dont have foam issues unless I speed carb a keg and then its only foamy for a few seconds.

I had to look up key kegs and after seeing the mfr website not much was cleared up. The fitting seems where a foaming problem could be stemming from if it wasn't mated exactly right. Over carbed seems unlikely with the bag in a ball construction. If other beers pour ok from that line this one should too.

if you have 1/4" lines and they're only 5', it sounds to me like you need longer lines, or at least switch to 3/16 to give more resistance.
Personally, I would replace the line with at least 10' of 3/16 and try it.

Hi

I'm running 20' of 3/16 and it seems to work very well up to at least 18psi.
