Default Can you add IBUs after fermentation?

Is it possible to do something like a hop tea with a long boil to add hop bitterness after a beer is completely fermented? I kegged an IPA that is WAY too sweet and am looking for a way to salvage it. I'm pretty close to dumping all 5 gallons as it is.

I added hops to my priming sugar once. I boiled about a quart of watter and a quarter oz of hops for about five minutes. It tastes just like a five minute addition (the other half of that batch was bottled unchanged.). Go for twenty minutes and you will get some IBUs. With a keg you would have to stir it in somehow.

I just did this a few weeks ago with a Saison that wouldn't dry out for anything. I boiled some hops for an hour in 1/2 gallon water, cooled the tea in an ice bath, poured it into the keg, and racked the beer on top. There was probably 1/4 gallon left after the hour boil, by the way.

This worked like a charm. I was really amazed how well the saison turned out. I wasn't expecting much, and I had been very disappointed with the brew before. Like you said, I was ready to dump if this didn't work.

It worked very nicely, and I'm happy to drink and serve the results.

Sweet. Thanks for the feedback Killinger. I don't think either of my LHBS have hop extract so I'll try the tea route. I'll see what I have on hand and boil it up tomorrow.

Hmm... I was thinking about doing this my IPA. I guess I mashed at the wrong temps and it's still a bit too sweet. I'm going to wait until it's carbed and aged another week or two though. I don't mind it a bit sweet, but it's not going to win any awards as it is.

Northern Brewer started selling the hop extract at some point fairly recently. Comes in a little syringe. Order that and some leaf hops and see how many Federal agents show up at your door!

Think I saw something similar on MoreBeer, too.

The HopShot extract is not isomerized, the Isohop extract is.

So what does the isomerization do for it?

Means you don't have to boil it in wort to get it to be bitter.
