Hehe, yeah, I would guess it is about normal. Absolutely not more than 1
cm sediment when the rest of it is absolutely clear. This is a possible
place of some loss though, as I opened the fermenter lid once every
other day to make a measurement of how far in the process I was, and to
make a comparison between the different strands of yeasts that I used,
so some oxygen may have been available and thereby letting the yeast
grow instead of producing alcohol, but it shouldn't have happened to any

there was in the mash. And it still wasn't much.

still, and it added up to what I put in.

No, not a chance :)
And as I did the out vs in check, there just isn't more alcohol in the
mash than what I get out.
Hmm... the mystery continues :)
- Ok, so around 4 liters of 92% alcohol from 8 kg of sugar.
Well, I'm still pretty far below, but not by more than perhaps 1 liter
But 4 liters of 92% alcohol is a pretty bad result also, as the
mash then only would be barely 15%, and it should be closer to 20 than

Not 100% but bloody close, 92-92% average.
