I set the target volume in the fermenter to 4 liters, but the recipe calculator fills inn 28.5 liters in the boil volume when switching from All grain to BIAB. I'm thinking these might be some faulty programing there, perhaps a mixup between liters and gallons?
The quick water requirement calculator works though, it says to use 9.6 liters of water at mash in.
