Mash in a Bag question

[Hawkbox]

So quick question, anyone know what I should put in for grain absorption losses? I don't actually do a BIAB directly but I do a Brew Bag in my mash tun.

Do these numbers track?

My loss seems to be 0.8 liter per kilo ... been pretty much the same for most of the time

Unless you're planning on squeezing bag or hoisting it to drain better id be starting at 1 L/ kg and dial it in for your system and crush

yep i use 1lt /kg but havnt given it much more thought i probably should set it less as i do squeeze a bit.

I don't know about liters and such, but I calculate .3 qts per lb and I have to lift the bag and squeeze it to hit the numbers just right. If I were to sparge only and not sqeeze, I'd have to figure on .5 qt/lb or so.

I do lift and squeeze. .3qts/lb would work out to .6L/KG which is roughly what I've been working with. I may bump it up a touch so I don't have to squeeze hard.

And I just realized why my brain didn't like that number. I was thinking 4lb/KG rather than 4L/Gallon(ish) and none of the math worked.
