making imperial stout

my friend wants to make an imperial stout on my 50 litre BM.
I am thinking if the grain bill is about 12 kilos(I havent seen the recipe yet) for a 25 litre brew length can I use the 50 litre malt pipe and add the minimum water required to cover the elements (I think that is 43 litres ) and adjust boil length to get the correct O.G
would this work,with the minimum amount of water and a large grain absorbsion will the element still be covered at the end of the mash?
what do you think

When I did 15kg of grain with 43L of water I had the element covered all the time. For 12kg I guess there is less grain displacement. I would say begin with 43L and have 1-2 liter ready on the side. That way you will make your own experiment. You can probably have 16kg of grain and 42L and still be ok.

First time I brew with the BM I forgot to read the manual and did a recipe with 15kg. It went well and so I did more and more recipe with 15kg.

It work good for me and I can do any beer up to 1.090 no problem. Next time I'll try 16kg with 42 l and I'm sure it will work.

Good luck with you stout

Cheers

well brew day done
here is the recipe my friend went for

Code: Select all
4.3 kilos pale malt
4.3 kilos vienna malt
0.58 kilos roast barley
0.35 kilos caramunich 3
0.35 chocolate malt
0.34 rolled oats
 
56 g magnum 14% 60 min
21 gr EKG      5%    30 min
42 gr ekg      5%     10 min

mashed in with 43 litres
mash 42c 10 minutes
         67c 60 minutes
         75c 15 minutes
90 minute boil
og 1.102
predicted F.G 1.026 10.1% ABV

to be fermented and kegged with vanilla pods and cacao nibs and aged for 3-4 months


the brew length was meant to be 19 litres but with the requirement for 43 litres of water the final gravity was lower than required .We could have boiled for an extra 1 hour to achieve the gravity but due to time constraints added 1.2 kilo s og DME to boost the gravity from 1.089 to 1.100

the mash was full volume no sparge but stopped and stirred 2 times.
by playing with beersmith I have found that by scaling the recipe to 25 litres brew length (adding about 2 kilos grain to above recipe)) I can brew a 1.100 beer with 90 minutes boil and 13 kilos grain in malt pipe of 50 litre BM,

flemming these numbers equate closely to your ones I think I was about 2 kilos of grain down on your but added the DME and ended up with 25 litres at 1.090 ish
