Default Beer went from 'great' in ferm, to 'crappy' in keg

I brewed NB's Extra Pale Ale kit about 4 1/2 weeks ago. Left it in primary for 3 weeks, cold crashed for 2 days and kegged it. I used my autosiphon that I had run a couple gallons of Star San through (and it was only the 2nd time I've used it). Tasted a bit from the primary. Tasted great!, just flat. Set the regulator to 30psi for 24 hours. Dropped to 12psi, waited about 24 hours, and poured one. wasn't over-carbed, but didn't taste anything like it did before kegging. It has a bitter off flavor. It's drinkable, but not good. What could have happened in 2 days?

As far as the keg, it was from Cornykeg.com. It had been setting for 7 or 8 weeks under pressure, with a little of what ever they cleaned the keg with, still in it. I noticed some dark stuff in the bottom of the keg. I assume it was soda residue that had settled out of the cleaning solution, and redeposited itself. I dumped the remaining liquid, and wiped out the residue with a paper towel.

Next, I put some properly diluted BLC in the keg, and shook it around really well, pressurized the keg, and pushed it out the tap. Then I added about a gallon of water, rinsed it out good, and pushed through the tap. I then added a couple gallons of Star San, and sanitized the keg, once again pressurizing with CO2, and running it through the tap. It seems like that would have been sufficient to clean it, so I'm not sure what happened.

It seems like if it tasted great flat in the primary, just carbing it would completely ruin the flavor...suggestions, anyone?

Thanks,
Pat

It looks like you did everything right. Co2 increases the perception of bitterness on the palate. You just need to let it age and come together under pressure for a couple weeks. It's what most people refer to as green beer still at this point.

Double D, That's what I'm hoping. Since it's been a week, and the flavor hasn't changed, I'm just getting worried it won't get better. If this is typical, how do people quick carb and drink their beer within hours of kegging it?

Depends on the style and recipe. My guess is you're just experiencing the "extract twang" that so many people talk about. It's also quite amazing what a person is willing to accept if they're in a hurry.

I wouldn't say it's necessarily typical, but not uncommon. Now that I've talked circles around it with out answering the question, is it possible you didn't rinse out the starsan? I only ask because I've seen some pretty crazy threads.

Within hours? I don't think that's even possible without a stone....even then, I'm not sure it's possible. Hell, I don't think you can even chill a full keg of beer within a couple hours (could be wrong).

I usually see the 2 week set it and forget it crowd or the several day burst, bleed, then serving pressure crowd.

Nope, didn't rinse the Star San, but I thought that was the point of the 'no-rinse' sanitizer? Not disagreeing with you, as I've seen a lot of threads too...
Unfortunately, the taste reminds me of my first 2 failed batches about 13 years ago...which is why I haven't brewed for 13 years, lol.

I wish I could describe the taste better. It doesn't really fit any of the 'off-flavors' that are usually discussed, and I don't think it's 'extract twang'. Oh well, might just pull it out of the kegerator, and let it sit for a while.

If you chill the beer, then carbonate at serving pressure by shaking, the change in flavor is less noticeable. This requires a very clear beer when you rack it.

It's not necessary to rinse Starsan, hence, this...

BrewThruYou, I see lots of threads about people quick force-carbing their beers (mostly cranking up the psi and shaking the crap out of it for several minutes), and proclaiming it to be awesome. My thoughts were, if I kicked it up to a higher psi for 24 hrs (no rolling or shaking), it wouldn't over-carbonate, and might be ready to drink in 4 or 5 days.

I guess the question I'm really looking for an answer to is, did my beer get infected in 2 days by something in the keg?

There's always the possibility that it's infected, but I seriously doubt it since it's only been in the keg for 2 days. I'm guessing it's carbonic acid bite and should go away in the next few days.

I found this on another forum: "When you force carb quickly, you create a bunch of carbonic acid right away. This will eventually neutralize and dissipate as the beer ages. With natural carbing and bottle conditioning, the carbonic acid is slowly neutralized as it is produced."

PS: I think the people that say that the beer is amazing after a quick force carb without a stone are full of it.
