Hello guys, does anyone have problems with correct water calculation for your brew? I brewed for the first time last week so I did not have exact numbers for my equipment so I've just use default values. Of course it was not very precise but at the end I've finished with this numbers: I finished with 26L of fermenter volume. Mash thickness I used was 3L/kg so I've used 20.5L of mash water and 17L of sparging water. So I've used 37.5L of water. Pre-boil amount was 29.5L.My problem is that no way I've change the variables in my equipment profile I can't get these number properly calculated. It always shows wrong amount of pre-boil volume. Therefore I've tried to use morebeer.com sparge water calculator and by settings the variables I was able to perfectly match with my real numbers. In the attachment you can see the comparison. Strike and sparge water is exactly the same but the pre-boil volume differs by 1L so I wonder if I can correct it somehow so it shows the same numbers. I've tried to changed all variables but pre-boil volume was always the same 30.7L. Thanks.
