When I lift the malt pipe I had 32l of wort at 1077 sg. I "sparge" with my 8 liter and ended with 40l of 1073sg. At that time I decided to decrease my efficiency to adjust to the estimated preboil gravity from beersmith. It take me to 60% brew house eff. Now beersmith called for 1094 OG. And the measured mash eff at 65%

My boil off was a little less then expected and ended with 31.5 L of wort in my fermenter at 1092.

Sorry I overlooked it, this was in the initial post, I thought you were referring to another post...

In order to figure out hop addition timings when doing boil time calculations.. Has anybody figured out how to calculate how long you need to boil for in order to bring your pre boil gravity to target OG

beersmith has a boil off calculator

just in put volume and S.G you have and evaporation rate and adjust time to get desired new S.G
and there is one here that works by volume

What is the minimum amount of water people have been able to use with the 50l malt pipe that still ensures that the elements are always covered with water?

bierfest I asked the same question here
viewtopic.php?f=8&t=238&p=2581&hilit=minimum+water#p2581

the consensus seems to be 43 litres

@paulg thanks for that.

Im almost finished my two recipes now for Christmas. Im planning to do @Dinnersticks Smokey the Barracuda porter and a Founders breakfast stout clone. Two big beers! Im going to try out using the 50l malt pipe for mashing the desired volume of grain and then boiling down to around 25l to get my deisred OG.

The Speidel manual recommends that the minimum amoung of grain in the 50l maltpipe is 9kg. In one of the recipes I will have slightly over 8.5kg. What is the minimum amount of malt that anybody has mashed in the 50l maltpipr and were there any problems with it?

Not a 50l owner, but I accidentally mashed in with only 3kg of grain and everything worked fine on my 20l. I think the 9kg suggestion is a nominal amount (rather than minimum) for the 50l. 4.5kg is the nominal amount for the 20l. So if we make a dangerous assumption, I'll bet you can get away with as little as 6kg in a 50l. I'd be pretty confident 8.5kg will be no problem.

BTW, I based my Maple Bourbon Barrel Chocolate Coffee Stout on a Founder's Kentucky Breakfast Stout clone recipe.

I've done plenty in the 8-9Kg range, a couple in the 7-8Kg range and one at 6.5Kg all with no problems at stage.
To brew or not to brew, that would be a stupid question !

+1 I did 45 litres of a mild with 6.5 kg also.
82% mash eff ,80% brewhouse eff ,according to beersmith, no wort fountains or other problems

Hi, everybody!
This probably qualifies as a silly question, but today I used 8.9kg in the standard malt pipe on my 50, and there was plenty of space between the top filter plate and the wing nut, around 7 cm or so. Is this normal with non-up-to-maximum levels of grain in the malt pipe, and should I be doing anything about it?

6,5 kg because I needed really low OG (1034) to make English style bitter (I love this stuff) :cheers:
I am thinking about getting the short malt pipe because the water/grain ratio on BM 50 is absurdly high and I bet, I can get even better taste for low ABV beers, if I can reduce the water grain ratio form >6:1 down to 4 or 3:1. I am probably going to see a slight drop in efficiency but adding few hundred grams of grain is not a big deal.
I make my own copper/ss chillers (immersion) - 20l & 50l and counterflow (cfc)
