158 ibus?

2 oz. chinook 12.5% - 60 min
2 oz. Hallertau 4.1% - 30 min
2 oz. N Brewer 3.9% - 15 min

158 IBUs according to this formula:

Is this possible?
If so, will it be drinkable?
Its been in the primary for a week.

I haven't made a bitter beer yet, but we were at a local brewpub last week and they had a 98 ibu beer that really wasn't much more bitter than many other ESBs.

It's possible in theory, but not in reality. About 100 IBU's is the max you're going to get out of just about any amount of hops due to wort gravity and other things in solution. What is your original gravity? If it's something low like 1.050-1.070 this is going to be very bitter. If you have a big beer in the neighborhood of 9-10% ABV, it will need some time to mellow, but should be drinkable.

That would explain why this beer was palatable. The 98 IBU beer that we had was 9.8% or something near there.

Would it be theoretically possible to put your bittering hops in, then boil it down in order to increase the concentration of bittering compounds?

 Brewsmith 03-28-2008 11:58 PM

Yes, but by boiling down, you are also increasing the specific gravity, making the wort sweeter.

What if you did an extract kit with hops, and didn't add extract until the end? You'd use extra hops and extra water(hops for say 10 gallons) and 10 gallons of water, then reduce it by half and then add your extract.

OG was 1.060
So ABV should be around 6%??

I was going to put this in a Keg and drink it right away. Should i bottle it instead so i can age it? Can i age in a keg?

From what I understand, its not so much 100 IBU's is what you can extract, but 100 IBU's is the limit of what we can taste. The reason that it doesn't taste as bitter in bigger beers is because there is more sweetness/alcohol to balance it out so you don't "perceive" it as being 100 IBU's of bitterness like you would with a smaller beer.

Oh yeah, let it sit for a month at least. You'll be glad you waited.

So can i put it in a keg to age it? This was going to be my first time kegging, so i dont know much about it. Can I put it in the keg, taste it, and then let it sit for a month or so if it needs it?
