Greetings Brewers

Post by mrboxpiff » Fri Mar 09, 2018 12:04 am

Does anyone have any idea how much water is displaced by around 12kg of grain? My mush run is 70 litre and I'm trying to workout what is the largest brew I can do (the boiler is also 70 litre)?

Thanks in advance

That should say Tun and not Run I guess?

On that basis it depends on your malt/liquor ratio. But your question is a bit too open ended really. Do you mean the strongest beer by ABV or the final volume.

Ah the joys of the auto correct. Yes I meant tun. The 60 litre is the estimated final liquor amount. I'm now thinking I may reduce to 50 litre and work up from there next time.

There is a caculator on the forum, but as scuppetter says its an open ended question. If you batch sparge or fly im guessing with fly you could getting more in. Same with your grist ratio

So making it a Mush Tun then. :D

12kg of base malt grain will absorb similar in mash liquour. You could do 50 litres @ 1.055 Mash volume needed is 40 litres so a 50 litre tun will accommodate it. Sparge to required boil volume. 60 litres @1.046 if you are happy to go less alcoholic.

This is at 2.63l/Kg.
