No, I don't think so because it's probably gunked up inside, not outside. Maybe the rubber o-ring has sort of melted/stuck (that happened to one of mine), or the post is full of crud. I got all of mine off, eventually, with some brute strength. (This is really funny, if you actually saw me in person! )

My "brute strength" also involved a mallet, a hammer, a deep socket, and lots of curse words. I think it was the old Army combo of "mother" and all the four letter words I knew that persuaded it to come off.

But check with the manufacturer of your keg, to make sure you aren't going to damage it. I have a mix of challenger kegs, cornelius, and firestone kegs, and they are different but they all come off.

OK,it's a Cornelius keg. The homebrew shop here said it was reconditioned, but of course it was not. I'll probably buy a deep socket and use a socket wrench and mallet. The thing kept turning when I was trying to get it off. Maybe if I get someone to hold the keg it would help.

Thanks for the help. I think this is probably the source of the problem. Gunk on the inside and probably a slow leak as well.

****, I took the keg apart and the dip tube was completely clean. There was no gunk inside the ball locks or anywhere. I still don't know where the acidic taste came from.

Now I'm thinking it could have just been overcarbed, because the beer lines were 1/4" and only 4.75 feet long. So if the wrong lines pull CO2 out of the beer, then I'm checking for the right amount of bubbles before I drink it and then it gets overcarbed? Hmmmm. Still not sure.

Not sure if it was mentioned what the proper lengths were, but there is a useful thread and excel spreadsheet for figuring it out.

I think you have two issues going on. The line length and diameter does affect foaming.

When I had my issue I never saw anything obvious either but the problem went away. How does your first pull taste now?

The foam problem doesn't bother me nearly as much as the fact that the beer tasted great for 8 glasses, and then worse as time went on.

The keg is now emptied (I drank it even though the aftertaste was pretty bad at the end). I cleaned and checked for leaks after it was empty.

Since it was clean and not leaking, the issue has to be the beer lines (inner diameter and/or length) causing the too much foam problem. And then the acidic taste is probably caused by the carbonation process not being done correctly. I don't know of any other way a beer could lose flavor and taste flat and have an aftertaste except for overcarbonation.

I just ordered 10 feet of 3/16" inner diameter lines.

Another spreadsheet for line length and pressure. This one is different.

Overcarbing making it taste flat? I think we're reaching a bit here.

Maybe you grew out of Shock Top?

No, overcarbing does make a beer flat. Weird, I know.

But what happens is the co2 is "knocked" out of solution on the way to the tap. That makes a big foamy head (or a whole glass of foam) that is comprised of co2. When the foam dies down, the underlying beer is lacking the co2 due to it coming out of the beer during dispensing (creating the foam). In that case, a flat tasting and feeling beer is indeed due to overcarbonation and serving with a line unable to handle that carb level (ie lines too short for that carbonation level).

But that wouldn't account for the taste issues would it? The fact it would change from the first pour and that it got worse over time...
