Hey Rob, I am looking and doing an iStout clone soon and wondered what size batch is this brewtoad recipe? The can you brew it recipe uses 11.6 kg grain for 23 litre batch and this is around 30kg.....other query was the hops. The 8wired website says it has Chinook and Cascade in it as well. Do you think it the recipe would benefit with some early additions of Chinook and Cascade?

Mark   not sure if you are using Beersmith,   if you are goto file/addons   add the can you brew it recipes....

here is istout   I dont think the grainfather will do this unless you scale it back towards say a 12L brew...    on the audio he says he gives this a second Oxygen blast at 18-24hours after initial pitch....

Its a huge beer, would fill my inside pot just to make a 23L batch...    maybe we could do this colab and split into my 2 smaller 19L carboys?   I have oxygen bottle, I would prob also pitch active 1272 and would def be doing a water additions spreadsheet given investment in grains

I didnt know that, cheers. A colab brew would be the go and will need some planning. Still a couple of brews away for me.

He states in audio that he normally uses 1272 but for the batch istout used "HUGE" way too much pitch of third gen us05 and he was in fermenter for 2 months due to Acetly issues. had to use fresh yeast to finish the beer, pitched 18C fermented 16C.

5.4 mash ph...   Oxygen 7lpm inline sintered stone saturated, used a wine yeast nutrient.

The batch was done as a much larger batch between about 6 people. about 48Litres in the end.

For mine, if you want to clone the recipe stick with the original and adjust for efficiency (base grain) If you wanted to use Chinook and Cascade, I'd swap out Southern-X for Chinook, and Willamette for Cascade.

I did a 13% coffee stout a while back - recipe below. I actually used 2 cans of light LME in palace of the 3kg DME but same thing. IMO not a bad option in a big stout if your mash wont take the grain necessary to get the volume and gravity you want. I wouldn't do it with a larger or IPA but with a big stout I really don't think you would notice the difference between a smallish ammount of  LME, DME or extra base malt with every thing else that's in there.

coffee stout 13% 40L

12 kg (64.6%) Pale Ale Malt - added during mash
1.58 kg (8.5%) Crystal 40 - added during mash
1 kg (5.4%) Dark Chocolate Malt - added during mash
1 kg (5.4%) Roasted Barley - added during mash
44.25 g (42.5%) Warrior® (16.0%) - added during boil, boiled 60 m
32.68 g (31.4%) Liberty (4.0%) - added during boil, boiled 30.0 m
27.23 g (26.1%) Liberty (4.0%) - added during boil, boiled 15 m
3 kg (16.1%) Dry Light Malt - added during boil
200 g Coffee (grounds) - added dry to primary fermenter

definately something to think about for small capacity imperial strength brewing. I used similiar grains as the iStout in a 2 can extract recipe, no where near imperial but wasn't too bad.

I think my post was supposed to go on the Large Grainbill thread which was also talking about iStout. Oh well its here now.

My iStout is down to 1.022 after 6 days in the fermenter. Still smelling very alcoholic but nice roastie flavours.

Wow, 1.022 very impressive.
