At our club's last executive meeting (our exec meets a week prior to the general meeting), someone asked about the annual Executive Brew, which, by the way, was overlooked last year. Normally the executive gets together and brews something to be shared with the membership at our December potluck meeting. We decided to brew a spur-of-the-moment, shoot-from-the-hip Imperial IPA using my 10 gallon system.

Our president donated an entire 25kg sack of malt that he won at our last competition, and he was hell bent on trying to jam every last gram into my mash tun. Unfortunately (or maybe fortunately), we couldn't fit it all in. We did, however, manage to jam the following ingredients into it:
  • 20kg pale 2 row
  • 1.0kg caramel 60
  • 300g honey malt
  • 200g roast barley
All in all, about 3x as much malt as I'd use for a normal batch.

I know, the roast barley shouldn't really be there but we wanted a red IIPA. We mashed at 146F (63C) for 60 minutes to encourage a very fermentable wort. Our president purchased 4 x 60g Chinook (12.1%), 2 x 60g Cascade (6.9%), and 2 x 60g Goldings (2.9%) hop packets for this monstrosity. The hops were added to the boil as follows:
  • 180g Chinook (12.1%) 90 minutes
  • 60g Cascade (6.9%) 30 minutes
  • 60g Cascade (6.9%) 20 minutes
  • 60g Goldings (2.9%) 15 minutes
  • 60g Chinook (12.1%) 5 minutes
  • 60g Goldings (2.9%) @ flameout
My brew program calculates the IBUs as 101. The OG was 1.093.

We brewed this thing on Sunday, and pitched a huge starter composed of 3 wyeast 2565 kolsch smack-packs. We selected this yeast because a) our local supplier had 3 packs of it (and nothing else), and B) we wanted a yeast that attenuates rather highly. Our president used his oxygen system to oxygenate the wort, and it took off like a rocket within 4 hours of pitching. Coincidentally, Monday morning I ordered my own oxygenation system. Had I known that a 60 second burst of oxygen would have such a dramatic effect, I would have purchased an air stone and oxygen tank a long time ago.

Today (Tuesday) things have settled down considerably. I didn't take a gravity reading, but based on experience I'd say this thing will be done fermenting within a week. It's probably about 60 - 70% of the way along. So I added the dry hops, selected from my own stock on hand. Each carboy received:
  • 30g Target (10.0%)
  • 45g Glacier (4.9%)
The aroma is heavenly. We hope to have this batch done, kegged, and force carbonated in 4 weeks. I'd say we'll easily meet that date. Hopefully it tastes as good as it smells, in which case I'll be sure to shoot from the hip more often. B)
 
wow. that is one big beer. let us know how it turns out. interested in how that yeast goes, and also how red it turns from the roast barley.

Would anyone mind throwing this beer into their brew program/software to see what the IBU level is? My very old version of Suds tells me 101, while a friend's version of Beer Tools figures the IBU level is about 220. We're both using the Rager method. I can't figure out why there is such a discrepency. I also downloaded the latest version of Suds, and it still comes in around 100.

This beer turned out fantastic. The FG came out at 1.011. This is one sneaky beer. Those in attendance at our club's executive meeting a couple of days ago tried it. It doesn't seem strong while you're drinking it, but 30 minutes later, look out.

Maybe I'm going blind. Is there a batch size and boil volume amongst all that info?

I get about 41 litres of finished wort from every batch I do. It's not exactly 10 gallons, but it's close enough.

checking you %abv, it shows 10.92% :excl:

you have been warned. enjoy!
 
Thanks for taking the time to type in the recipe for me. I have no idea why, but for ridiculously high IBU levels Suds tends to plateau at about 100. A member of my club has double checked another recipe of mine, and his Beer Tools reports 19.8 vs my Suds at 20.2. It's nice that Suds is accurate at lower levels. I was getting worried that all of my previous brews were horribly out bitterness wise.
 
not a problem. glad to help.
at least now you know what you're tasting...if you have any tastebuds left ;)

Is this suds program windows software, I like the sound of it. The bitterness compounds in hops have a maximum solubility on wort up around that level - I think youll find that you could double or triple the bitterness addition with little to no increase in bitterness.

I think you're right regarding the maximum solubility. I was beginning to think that Suds had a bug, but now I'm wondering if the other programs don't have a bug!

You can find the newest version of Suds here. I personally still use an older version (v4), but I downloaded v6 and it reported the same IBU level for the IIPA as v4.
 
Gday newguy
I dont think the other programs have a bug, I just think that they have not programmed a ceiling in there anywhere. I know that a friend of mine has been in contact with Mr Tinseth about helping to rectify this anomaly, but it sounds as if Suds has already done this (does it come in Mac form I wonder?).
There was also a beer called Shazamm made by the local state (province) brewers guild, and it was quite bitter. They sent it away to a brewery lab for IBU testing, and it came back about 120IBU. The lab guy ran the test 3 times, cause he thought the computer had made an error. So, it IS possible to get over 100IBU, but I think it is REALLY hard. Some blokes have made a "400IBU IIPA" according to promash, but a trip to the lab proved it to be about 92 (if I remember correctly) IBU.
Anyway, looks like a great IIPA, and I am sure that the members will enjoy it. If I ever make it to Edmonton, I'll be sure to try and look you guys up - sounds like a "live by the seat of your pants" kinda club!
All the best

Trent,

By all means if you're planning to be in the area, let me know. Regarding Suds, I'm not sure if there is a mac version. You might have to use the pc version but run it under a windows emulator/whatever. Now that I've accidentally discovered this "ceiling" feature of Suds, I'm even more impressed with it. The only thing I'll warn you about is that I actually don't like the layout of Suds v6. V4 is much better, but old.

Another thing that I've been thinking lately is that hops do to humans what catnip does to cats. There is no way that 100ml of 12% beer should have made me wobbly. Same goes for everyone else who sampled that beer. If we had each sampled a 12% wine instead of the Hulk, we would have been fine. Has anyone else noticed a correlation between hoppy beers and feeling funny (yes, I'm aware of the closest plant relative of the hop)?

Well are here are two herbal sedative recipes ... one using catnip and one using hops.
1.5tsp of hops in 1 quart of water. Just squinting at the recipe and trying to imagine that much hops ...
you probably did use at least that much per quart!
