Can you help me to understand the difference between mash effiency and conversion effiency?

Thanks for this. A lot of wisdom to lurn from. I will🍻

It has and the minium is that 12L. So if I use that (as I did) and rinse after that with spargewater doesnt it lower the overall gravity? Or does rinsing mean something else in this?

Yes I use BrewFather. I just havnt seen anywhere that you could start with less than 12 litres... but maybe I´ll check that my self. Or If anybody knows the answer already..?

Hi. In my case the 2,8Kg of malt is the maxium for BM10 so adding more malt isnt really an option. And if I rinse, wont the Preboil gravity go down? If I could use 10 litres of water for mash and 2 for sparge it would give me better numbers, but with BM10 its instructed to start with 12 litres.

Hi Im a former biab user and just now I have updated my system with Braumeister 10 litre version. I have a question about the affect of sparge and effiency. So, I have done one mash with 2.8kg of malts and 12 l of water... and I used no-sparge. With this the mash-effiency was 59%, Preboil...

Shure

Good point. I'm not worried about not making good beer from this. Just wondering if the numbers work like this. Do you think they do? Ps. I know same numbers don't make same taste (necessary).

I designed a recipe that has only whirpool hops after 60min boil and dryhops later. I had a little family emergency and the boil time something like 95 minutes. So there was more boiloff and less wort after the boil. I still use the same amount of hops as in the recipe (just whirpool and...

Ok. I think I found my remaining problem. I didn't calculate the temperature expansion to boil off. Before I compared preboil to cooled wort. When comparing preboil to cooled wort*1.04 I get about the right numbers.... I think...

I actually would like to be able to choose and lock the total water amount used and then chance the other values after that. But I guess that's not possible.

I know. In BF there is possibility choose that do you insert the preboil volume (FB calculates boil off) or do you insert boil off (FB calculates pre boil volume). And with all the info it calculates the total water amount needed. And I can't get these match unless I enter some variable that...

One more stupid question : is the preboil volume in BF the volume after the mash and squeeze? Somehow those calculations in BF gives me too small boiloff rate...

Man I should have been wake in a maht class. So this starting to make more sense now.

Oh no! So it's something like this: (6.4l - 6l) / 1xkg = 1.066kg/l
