I read once that there was a limit to what humans could perceive in terms of IBUs. I don't remember the number but I know it wasn't 3 digits. I don't know anything about the credibility this source though. Just something to consider. Either way that is WAY over what any style calls for. IBUs alone don't make a beer hoppy. It's a combination of bitterness, flavor and aroma. I'd suggest going with 1 oz Warrior at 60 and using the money on the other two ounces for more at 15-20 minutes for flavor. You'll get plenty of aroma with the 5 min and dry hop additions. That's just my 2 cents.

Oh, and check your hop source. Today's Centennial are often "Centennial Type" hops made from a blend of other hops (due to the shortage) that supposedly comes close. Cascade and Amarillo are other great options. I haven't used Simcoe yet but I've read great things about it for hop flavor and aroma.

My favorite IPAs get most of their IBUs in the last 30 minutes.

Looking around the net it seems like it's fairly close to Ruination. I still think you should use less Warrior.

HOOTER · 03-17-2009, 06:43 PM

You can start by cutting the bittering addition in half. Warrior is an aggressive hop and 1-1.5 oz. would be sufficient. I would think about doing three Centennial additions, maybe 1.5 oz. @ 20 min., 1.5 oz. @ 5 min., and 1 oz. dry hop. "Hoppy" isn't so much about bitterness, but about a balance of bitterness, flavor and aroma. Your hop schedule as it is now would make for a very bitter IPA with tons of hop aroma but mild hop flavor.

Also, I would think about a blend of crystal malt to add some color and complexity. Maybe .5 lb. of crystal 20 and another .5 lb. of crystal 60 or something like that.

Finally, make a starter with your liquid yeast. That's a fairly big beer and a yeast starter would help immensely.

That's all I've got. With a couple minor tweaks you'll have yourself one fantastic IPA.

Looks like a tasty brew man! I would maybe spread out the 2oz centennial addition over the last 25 minutes or so, which would add some flavor and give it a few more IBUs. You are going to be dry hopping, so you will get a lot of aroma from it, but it doesn't contribute to the hop flavor or IBUs from what I've read. Also, the more wort you actually boil in your kettle, the more IBUs you will get. This looks pretty similar to the ruination extract clone recipe, except with more IBUs.

There is a difference between a super hoppy beer and a super bitter beer. I prefer my IPA's to be overloaded with late additions and i like to keep the IBU's around 70ish.

My last IPA my Hop schedule looked like this:

1 oz Galena @ 60
1 oz Centennial @ 20
1 oz Centennial @ 15
1 oz Centennial @ 10
1 oz Centennial @ 5
1 oz Centennial @ flame out

1 oz Centennial @ dry hop
1 oz Cascade @ dry hop

Had a nice bitterness and awesome hop flavor and aroma.

You'd better kick up your pre-boil volumes because you are going to have about 3 inches of hop goo in the bottom of your kettle when you're done.

calpyro · 03-18-2009, 03:24 AM

Lots of hop goo for sure. My Beersmith says 12 gallons, but I really just fill the keggle pretty much to the max to accommodate hop absorption. Aside from that, I just run a little short of 10 gallons.

I prefer a lot of IPA's that are well balanced with flavor and aroma, with a nice bitter bite. Seems your recipe may be a tongue splitter, but missing the aroma and flavor to balance it out. I brewed a 100 ibu IPA this weekend (2.9g FV) with the following hop schedule. Love the latter Centennial and Cascade. Og on this was 1.070 and i will dry hop with probably 1.5 - 2 oz of equal Centennial and Cascade to balance further. Mind that this was a FV or 2.9g

.75 Columbus 13.7aa 60 min 62ibu
.35 Centennial 10.6aa 30 min 15.2ibu
.35 Centennial 10.6aa 20 min 12 ibu
.35 Cascade 8.6aa 10 min 5.8ibu (probably negligible)
.5 Cascade 8.6aa 5 min3 4.6 ibu (again negligible)
.15 Cascade 8.6aa 0 min 0 ibu
