Gonna be brewing later today. I use Priceless Brewing calculator to get my volume.
For those who BIAB and do full volume mashes, I have a few questions:
-Do you put a value in the sparge volume field? if you do what value do you use?
- Do you leave grain absorption and hop absorption set at default value?
- What value's do you use for kettle losses, packaging losses and mashtun losses?
For the brew today, here are my numbers:
11.85 lb grain
8.75 oz hops
grain & hop absorption left at default
kettle loss .5 gal
packaging loss .5 gal
mashtun loss ?? I used .25/gal
boil off for my system is about 1 gal/hr
60 min boil
with these numbers the calculator shows 8.8 gal total water. If I remove the mashtun loss value then the total strike water drops to 8.51 gal.
When I rack to fermenter, there may be a 1/4 gallon left, if that. So the total water seems about right but I've seen some who use about the same grain bill and use a gallon less of water. My numbers are always close to what they should be, most times a little over meaning gravity is a little higher.
Basically just want to make sure I'm calculating right.
