If you use the calculator keep in mind two things:

1. Evaporation rates are extremely variable and are set-up and operator dependent.
2. The water absorption rate will also vary with the same factors mentioned.

So the volume numbers could be fairly off depending on both of these things.

Indeed. You can always change the numbers to fit your setup.

Two other considerations also...

1. Trub loss
2. Cooling/Equipment loss

The latter is huge for me (upwards of 1.25g) since I recirculate and use a CFC. I think I am going to make my own verison of this and factor those elements in.

Thanks for this!

John

Here is what I came up with:



I have attached the XLSX if anyone wants to play with it. I had to name it as a PDF to be able to attach it here. Just download it and change the extension back to .XLSX.

BTW...not trying to steal anyone's thunder. I just saw some gaps that I know would impact my volumes.

FYI...each item on the left will produce a tool tip if you click on the cell:



I am open to all/any feedback!

John

Hi johnodon,

That calculator is nice and could be handy to use. I have a question regarding your Grain Absorption value. I have read that the normal grain absorption value is 0.125 gal/lb.

In your example, is the 0.075 gal/lb number you use based on after squeezing the grain bag or before?

Thanks,
Trip

that should be based on squeezing.. if you squeeze REAL hard you can lower that to .050

thread resurrection. I have heard no problems with squeezing. I plan on squeezing tomorrow when I do my first all grain batch using BIAB

Would this calculator work with no sparge brewing? I think the concept is similar to BIAB...
