Minimum grain quantity in 20L Braumeister

Unread postby Dr Jacoby » Mon Nov 03, 2014 7:06 pm

I'm looking to brew some small beers, say under 3.5% ABV. DO any of you have experience using smaller grain loads in the 20L braumeister? Do you have problems with the pump forcing the liquid up too quickly through the grain? What do you reckon is the minimum amount of grain you can get away with?

Hi Dr Jacoby,

I regularly brew a mid strength Aussie Lager at 3.5 abv using 3.34 kg of crushed grain.
It all works fine for my mill crush of 1.2mm although I have noticed small raised discharge at the top of the mash during the time when the pump is running. This has not caused any problems.

If you had wort fountains you could crush your grain a bit coarser and if you loose any efficiency then you could add a little more grain. In that way it would probably solve that problem altogether.

I would imagine that 3 kg of grain would be achievable in the standard 20 l BM malt pipe.

Cheers

Through a data entry error, I accidentally put just 3kg of grain in a recent cream ale (it was supposed to be 5kg!). The mash went perfectly normal and I didn't realize my error until my end-of-mash gravity check. Saved the brew with a quick trip to the LHBS to get some LME. I even thought to myself as I was mashing in, "Hmm, this seems like a very thin mash."

i have only had problems with small grain bills (>4kg) when doing overnight mashes. once or twice the channeling was quite spectacular, but the efficiency was always very high. i think if supervise the mash and stir it as necessary you should be fine?
