Double Jack Imperial IPA - All-grain

[JNish]

I love this beer, by far one of the best IPAs I've had. I have the Union Jack recipe from Tasty McDole and the CYBI team and tried first just scaling that up, but with the hop utilization going down the tank with a 1.090 OG, upped the hops quite a bit. Also subbed Magnum for Warrior since that's what I have in stock, but I've heard they're similar in clean bittering quality. And man, all the hops are low in %AA this year. Has anyone else noticed this too?

Brewing tomorrow, hoping to get some feedback. It's my first IIPA too, so any general tips appreciated too! Note, I do have a 3L starter going right now for this.

Quite the hop schedule, but it seems like there should be some additions with 5-10 minutes left in the boil.

Also, do you really boil off 2 gallons in 60 minutes? That seems pretty high...

Cheers!

Everyone's system is different, but he's got a 90 minute hop in this, and 2 gallons doesn't seem out of line. That's pretty similar to my system.

I was following the Union Jack recipe from Can You Brew It, and they only have an addition at 90 and 30 minutes, with the rest at flameout and dry hop. I'll look around to see if there's any other recipes that have later additions. I was basing most of the recipe on this one.

And yes, I use a 40qt stock pot that seems to boil off about 1.5gal an hour. It's pretty standard for me to boil 8 gallons. Plus it's a 90 minute boil.

As the recipe clearly specifies "60 Minute Boil" I assumed the 90 minute addition was FWH...

Cheers!

Whoops! I'm still getting a hang of the new version of BeerSmith. Thanks for the catch!

Looking into Tasty's recipe some more, he says that he does a whirlpool for 20-30 minutes prior to chilling after flame out. Turns out you have quite a bit of hop utilization during that time, so he counts it as a 20 minute pre-boil addition when calculating IBUs. More here.

Since I have an immersion chiller and whirlpool after chilling, EricCSU advises to let the flame-out hops steep for 30 minutes before chilling.

BTW, turns out I ended up going ahead and brewing tonight. It's a late night but looking forward to seeing this bubble tomorrow.
