Imperial Stout recipe for comment

[richc]

11.00 kg Maris Otter
0.25 kg Crystal Malt
0.25 kg Dark Crystal Malt
0.25 kg Pale Chocolate
0.25 kg Roasted Barley

90 minute mash at 65C

70.00 g Magnum 14% 90 mins

Assuming 55% efficiency (dropped from my usual 65% due to high gravity) that gives

1.099 SG and 78IBU

That looks okay but I like it to be a bit more roasty with probably twice the percentage of the roasted barley and chocolate or maybe introducing another dark grain like black malt.

Your recipe will still make a tasty beer though - what character are you looking to get from it?

Also, what yeast are you planning on using?

Good point, .55kg roast barley and add .25 chocolate as well. I'm trying to get some kind of dark fruit/roast balance in this.

I'm planning on using the US-05 I washed from a batch of Robust porter I made a while ago. So loads of yeast I hope....

[jimp2003]

Looks good.

Good job you will have plenty of yeast to pitch. Getting that right and good aeration is so important for this strength of beer.

What sort of colour (EBC) are you expecting?
You could also add a portion of sugar, this will save you having to try and mash such a strong beer and lighten the body and make the Stout more drinkable.

Good luck

You may want to consider adding an addition of hops around 10-5mins for a bit more fruitiness. Not a fan of roast barley as I find even in small amounts it gives too much roast. Maybe up the chocolate to compensate as Jimp suggests.
If you want more colour try adding black malt to the last 5 mins boil. You're not gonna see through it so clarity is unlikely to be an issue.

That should come out about 130 EBC. The sugar might be a nice idea, may be swap 1kg of grain for equivalent, might actually have some jaggery kicking around that might add a little extra something.


Would late hops add much, I suspect that I will be ignoring this beer for at least 6 months by which time I would expect most late hop character to have gone.

Sounds good... I'd almost always add late hops, these big strong beers are great for using up odds n ends too
