So Sunday I will be doing my first full volume BIAB with my gas burner and 33L pot (only done extract in it previously). I've got a Lakeland 'grand remoska' rack as a false bottom, so the bag doesn't squash the hop filter. Fits nicely though a bit pricey at ã9.99 but ordinary cake racks weren't high enough to clear the filter.
Anyhoo, the thing I wanted to ask was...
If I'm doing a 20L brew, with a 4.5K ish grain bill, how do I calculate my mash water volume?
Given the grain volume and pan size I was thinking about 25L mash water. I want to do a no-sparge BIAB as dont really have anyway of separately heating any volume of sparge water while I use my pot to mash in.
I've no idea how much water the grain will absorb, or how much I'll lose in the boil, but I figured that I can always top up to the 20L after the boil if I've lost too much.
Any experienced biabers got any suggestions for getting the right final volume in the fv?
