Making bigger beers with the BM.

[Dicko]

whitegoose,

If you press the Stop /Back buttons simultaneously it will pause your machine and you may stir your mash and then if you press the left button it will resume your set program.

The LED will have Continue on the left hand side of the screen and Abort on the right hand side of the screen.

The Stop /Back buttons are the two on the left hand side of the control panel.

I hope this helps

Brilliant, thanks Dicko!

Has anyone ever done a double mash starting with the small malt pipe?
If I have another screen for the malt pipe, then it would be possible to mash with the short malt pipe, lift it, position the normal malt pipe, add malt, move the top screen to the long pipe and start the secod mash while sparging the first on a bucket...

Cheers

Hi guys,

I've just brewed a 1.074 beer with a 6.7kg grist today on my BM20. It was milled at 1.5mm, I didn't stir the grain at all throughout the mashing, just let it go.

My mash schedule was a fairly long one, though (over 180mins when you account for rise times):
Mash in at 25C
40C for 10mins
52C for 15mins
67C for 60mins
72C for 30mins
78C for 15mins

I adjusted the water to hit about 5.2ph. Mashed in with 25L water and rinsed with 9L very slowly!

I was fully expecting a fountain or the pump to unscrew itself and leave due to the force it had to get through the grains. The mash was incredibly incredibly thick, though!

I probably wouldn't do this too often, though!

Cheers,
Nath

That is a great effort Nath.

I did a 6 kilo mash with my crush at 1.2mm and the pipe had a small space left....I was guessing around 400 to 500 gramms at the most.
I was surprised that I didn't drop efficiency at that volume either.

What was your mash efficiency at that amount of grain??

[Nath83]

Thanks, Dicko!

I was very surprised that everything went so well. It was one of my free brews I got from the LHBS when I bought the BM. I asked him if it'll be ok with that much grain and he said it should be. I was still skeptical.

I didn't take accurate water level readings pre-boil, but my SG was 1.064, 2 points higher than expected. I think it worked out to be around 95%!

Next brew I'm doing will be only around 4kg grain and will crush at 1.2mm so I can get the system dialed in better with Beersmith.

I'm curious too - how was your efficiency?
I've never seen a change in my mash efficiency - from Milds (3.8kg grist for 1.040) through to IPA (6.5kg/1.062) - Always sits around 82-84%

-Edit - was typing the above as you posted Nath

I was getting around 90-95% sometimes too - until I got some accurate volume measures

[Nath83]

Yep I got about the same from memory. It certainly was scary putting the last kilo of grain in.

Hi Guys,

Excellent thread here. I love my bigger heavier beers so I'm glad to read up about the successes had with doing this in the Braumeister.

Thanks!

I've now brewed a handful of beers with a SG >1.060 withoeut a problem. 13lb Grain bill, Stir a lot at start of mash, step mash, sparge with 1.5-2 Gallons, 90 minute boil.
I get about 5.5-6 gallons going into the fermenter, and 19l into the keg

Max grain bill to date is 14 lbs 3 oz

I've only had "fountains" when my grain-bill was 50% wheat.

i'm definitely interested in those numbers, but can some math whiz please translate them into base 10??
