Adding bittering hops after fermentation
 

Hello I have made an all grain bitter and left it now 2 weeks to ferment out. I checked the SG and it has fermented out.
I sampled it and it is not bitter enough!
Is it possible to boil some extra hops for instance 200g for an hour and pour this into the beer to make it more bitter?

Sure you can. Don't know how to calculate it, but I'd do a small sample amount and add it to a small amount of beer and then scale up.

They sell products to the commercial market for this http://www.hopunion.com/1020_IsomerizedHopExtract.cfm?p4=open and you can also buy small quantities from places like freshops.com

Thanks Samc

search around here for making 'hop tea'....there might be some useful calculations in some of the posts. I don't think you get very good hop utilization due to the lack of wort (just water) but it does work.

If you need to add a bunch of bitterness using this might be a better choice.

Sometimes beer out of the fermenter will taste a bit bland, when carbed and conditioned it will be different and perhaps more to your liking...ymmv

After many years of brewing, I am still amazed at the changes in a beer as it matures.

absolutely can confirm this. i just kegged EdWort's haus pale ale, and found that at racking - it was lacking! after just a few days on the gas, it has a LOT more character - not as sweet, more aroma (estery), and much more bitter. kinda crazy what that co2 can do

200 g is what, 7 ounces? Seems like a lot.
