just got an email from a friend who tasted the 120 Minute IPA

have you ever made a brew with a continous delivery of hops throughout the boil?

looks too good to be true

My refractometer doesn't go to 45 plato.

My 400IBU APA & a mere baby at 9.5% was made with 19 different hops added every 5 mins of the boil - 57gms (3gms x 19 varieties) in every addition. i had to make 461 hop weighings before i started. The keg is very nearly finished & just planning the next big beer...

400IBU!!! how long til that's drinkable? was it all grain or extract? what was the malt list?

2 weeks fermenting & dry hopping - kegged & into it on day 1. had a brew meet here the night it was kegged & all but one loved it. The poor guy who hated it had never drank a beer with added hops before & reckoned he could still taste them days later - lol.
Copy of ahb post here:
Inspired by just-cj's hop 10 cubed, I've come up with my own insane brew to see out 2006. I stock 19 American hop varieties, so as the name implies (R = 18 min) I've hopped with every variety. Rather than use the bucket & mix method, I weighed them all out tonight into 19 packets, so 3gms of every hop in every addition.

Looks great Ross

Having made a few IIPA's, with IBU's of 100+, I really question whether you actually get close to what Beersmith etc calculate on paper in terms of IBU's.
Would you say that this beast tasted close to 400IBU Ross?

blandy · Post by **blandy** » Thursday May 31, 2007 9:11 am

400 IBU

Rager or Tinseth, that's a HUGE IBU

and the final gravity wasn't that high, so you're gonna taste every single one of them!

by my calculations:

Alcohol: 2 beers in 1
Malt: 2 beers in 1
Bitterness: 10 beers in 1

Hey, if nothing else, it would probably make a good cough syrup.

Cough syrup is meant to STOP you coughing, KIP

No, you definately reach a freshold around the 80IBU level when it comes to bitterness, but you can certainly taste the extra hops. Now this has had 5 months in the keg, it tastes less bitter than a freshly made apa with 60IBU. Still a bloody nice beer with an incredible depth of flavour to it.

cheers Ross

Bloody convenient, having yer tucker and yer grog in one handy pint. It's a meal unto itself!

I would tend to agree with you. From my taste perception the IIPA's I've made they haven't even come close to 80IBU (thats around 100-120 calculated IBU) probably 60 at max. But you can definately taste the extra hops

I think it's about time I made another one actually

I`m sure GT over on Grumpys claimed hops maxed out at 100 IBU, regardless of how higher you went/added.
Could be wrong though, it was a fair while ago and you`d never find it on the search with so many hop threads on there.

Seems to make sense, anyway. Once the concentration reaches a certain level, the wort will be saturated and no more can be added. Can anyone find the suluabliity product for alpha acids?

I've searched far & wide to no luck. It's a bit of a grey area actually. I mean people can't even agree on the right formula to use to calculate IBU. & when gas chromatograph tests are conducted results seem to vary from calculated IBU's.

There were also claims that our taste buds taste the difference in bitterness above 100IBU.

FWIW I don't think that IBU's max out at a certain number. I think as the concentration of hops climbs it gets harder for the wort to absorb the AA. The threshold is more of a curve than a cutoff point.
I think you'd have to try damn hard to actually get a beer to 100ibu. & I guarantee if you do actually get it to 100 your Rager/Tinseth etc calculated IBU will be massive - somewhere in the range of double, triple or even quadruple.

Thats just my theory though
