Help with my RIS

So to commemorate the end of the world next year I’m going to brew an RIS this month to age for a year. Due to the size of my mash tun I’m doing a 18lbs mash with 6lbs of extract to put me where I want to be for gravity. My efficiency usually runs close to 68% and I realize it’s gonna suck on this batch I may even do a partigyle just for fun since that’s a lot of grain to only do one batch.

Here’s my recipe tell me if it looks ridiculous and thanks in advance.

14 lbs 2 row
1/2 lb Crystal 40L
1/2 lb Crystal 120L
1/2 lb roasted barley
1/2 lb Black Patent
1/2 lb Chocolate
1/2 lb Melanoidin

6 lbs Light LME @ 15 min

5 oz Columbus 60 min
1 oz Cascade 30 min
1 oz Cascade 10 min

Yeast will be an S-05 yeast cake I’ve got from a cream ale.

I hoping for something with some dark fruit character. I’ll probably keg it and force carb and then bottle off the keg.

heres what my beersmith says

Amount Item Type % or IBU
6 lbs Light Dry Extract (8.0 SRM) Dry Extract 26.09 %
14 lbs Pale Malt (2 Row) US (2.0 SRM) Grain 60.87 %

Beer Profile

i would say that is A LOT of IBU’s for a IRS. might consider less than 5oz for bittering. but its up to you i suppose… aerate as much as you can, and id recomend some yeast nutrient for this is a VERY big beer

3oz of columbus at 60mins would give you about 90 IBU’s which i would say is a little more reasonable. but like i said, its all up to you

Thank you. Does it look okay for the grain bill I know it’s a good dose of hops but I’m not really trying to keep too much to style. Also since I do plan on aging a year do I need to worry about the hops fading or if they do maybe it will make it that much more interesting?

I kind of also have a few yeast questions should I try to wash the yeast?
Can I pitch directly on the yeast cake and aerate with a mixter or should I try to aerate then pitch the yeast?
Is yeast nutrient necessary given the amount of grist or will that simply not provide enough nutrient?

the yeast cake should be enough yeast. you can pitch directly on-top of it. you could aerate before or after, i don’t think it will harm the yeast. for me, i would still use some nutrient, its probably not necessary, but with a beer that big you’re risking the yeast dying off too early, you really want to give the yeast the best conditions possible for a beer with that high gravity. the grains look good to me, i might drop the melanoidin but thats just opinion. good luck and happy brewin!

aging will definitely benefit a beer this big. let it develop over years if you’re patient enough

Thanks for the help maybe I’ll send you a bottle. I threw the melanoidin in the hope that it would help out the overall malt flavor.

What amount do you think?

I’m reading Designing Great Beers and am still very new to creating my own recipes if this thing is good and the world doesn’t end I plan to brew it once a year and keep some around to compare it and build my cellar stock.

Edit sarcasm intended.

keep in mind, 90+ IBU’s is a lot, roasted malts are the primary flavor in an RIS in my opinion. and like i said before-- aerate, pure o2 would be ideal, but if you don’t have that, make sure you aerate as much as possible. i would defiantly use a good yeast nutrient. beers over 1.100 are a serious challenge, you should research high gravity beers and search related topics on this forum.

if you haven’t seen this already; go to for calculating how much yeast you need.

again, good luck :cheers:

Since you’re after some dark fruit type flavor, I would drop the crystal 40 and use pound of 120. I’m not sure about the melanoidin; I would be inclined to drop that and up the roasted barley to a pound.

I think this will come out great. I do something similar that maxes out my mash tun.

I’m not sure if you already brewed this but here are my 5c of advice.
Drop the Crystal 40L
Use a pound of Crystal 120L
Use a pound of Chocolat
Drop the IBUs to 80 MAX

The bittering on a RIS should come from the roasted malts not the hop.
If you want you can all aroma and flavor hops.

Also add the roasted grains to the vorlauf and not the mash, this will reduce adstringency.

I’m happy to report we brewed this today and the entire process went off with out a hitch.

Thanks guys for all your help.
