Can a beer change dramatically in a keg after a few days?

Hey everyone,

I started drinking my Belgian Dubbel exactly one week ago. And tonight I had my first glass of it since Sunday (4 days ago) and noticed that it was quite different. When first drinking it for the first couple days it was VERY fruity and bubblegummy but tonight it has more of a hoppy flavor with much less of the bubblegum aroma. The bubblegum aroma and flavor havent vanished but they are considerably less.

What happened??? Its not bad at all, its very good infact. It has just changed quite a bit from what it originally was. The carbonation went up a little bit but I cant imagine that that has changed it to this extent.

I'm drinking it at the same temp and everything.

Any thoughts would be greatly appreciated.

P.S. When I started drinking it a week ago it was carbonated to the desired level. I first chilled the keg in the fridge on Tuesday night (of last week), force carbonated it at 10.5 psi at 37 degrees F. on Wednesday, and tried it out Thursday and it was great.

Anybody at all? Someone must have heard of something like this before. The beer changed a lot in just 3 or 4 days of sitting in the keg. I've never read or heard about this happening. Thanks. ~S.T. Out

It conditioned and got better...I wouldn't complain. Or...it's gone bad, send it to me for disposal.
It absorbed the carbonation due to the chilling. Man, I wish I had the patience to wait that long, Drink up!

BTW, are you in Portland?

Ya, your beer just conditioned, thats all. It'll get even better if you wait even longer.

Quite normal. I've got bottles of porter under my bed that taste nothing like the beer I bottled a few months ago.

Okay, I'm from Portland as a kid. Pretty place, that Eastern side...Smith Rocks comes to mind, but that's Wash. isn't it? It's been 20 plus years..

The chemicals that produce the bubblegum flavor can be consumed by the yeast in a rather short time. A little surprising, though, at 37F.

Yes, it can go from 5 gallons to less than one gallon in a matter of a couple of hours.
