RIS recipe check!

I’m planning to brew this beer on Sunday and thought I’d pass it by the jury. Any feedback would be appreciated.

More roast barley, less brown malt?

That looks to me like an unnecessarily complicated hop schedule, too.  I hope your yeast can handle that gravity.  Will you be bottling this?  Just curious.

Ron, with that little roasted malt, you’re going to have more of an imperial porter than a RIS.  You need a lot more roast to stand up to the load of malt you have in there.

Otherwise, the grist looks rather familiar  ;D :wink:

5 min hallertau looks out of place.
don’t think you’ll get much out of separating the 60 and 75 min additions - I’d just combine them.

might want to use 3 packs of US-05 or use fresh slurry instead.

On second thought, I think your right about the roast barley. I’ll bump it up a notch and recalculate. The hop schedule is somewhat flexible at this point. I will probably tweek it a bit before Sunday.

and Paul your about right…I just checked Mr Malty. I need about 3.5 packs for this big boy.

Jury’s still out on this one but getting closer.

Thanks for the input.

the roasted barley, black patent, and chocolate in mine total around 9% (off the top of my head).

also, don’t forget as it ages those will mellow, so keep that in mind.

Valid point taken. I definitely want to age this properly.

So far, I think mine’s been aging a little over 3 months.  I plan on letting it go until next fall.  It will be next winters big beer.  I tried to model it after Old Rasputin.  Only time will tell.

I take it by your post that Ron used your grist?

Got some 2 year aged going right now…yum…

His is similar, but a bit stronger.  I did not use any brown malt and I used crystal 80 instead of 120 and of course, quick oats. And no Victory either.  Actually it’s nothing like mine. ;)  I only had two hop additions as well.  One bittering and one flavor.

What efficiency did you guys (Paul and Jim) get on your latest batch?

I entered 65% for my brewhouse efficiency.

68-69% actually - I always enter 65% as well - never hurts to lowball the big guys, IMO.

to give you some scale, I usually get 77-78%.

That’s what I thought. Actually 69 is pretty good for a 100+ beer IMO. At least for single infusion+batch sparge technique.

I set mine for 65% for big >1.090 beers as well although my DIPA is ususally around 72-75%.  I attribute that to the cane sugar addition.

What was your actual efficiency for your RIS?

Yeah…Maybe if you’re using a blue mash-tun…  ;D

Roger Dodger.  8)

I think it was 65%, but it may have been 63%.  I don’t have acces to that information at the moment.

How long are you planning to let this one age?

I plan to age it for 1 year.

I brewed my RIS yesterday and hit my target after a 3 hour boil. That’s right 1.100 !!! It was the maiden voyage on the Brutus 10 as well. A great day!

Here it is…
