Tomorrow I plan on christening my newly built mash tun. For the last year I've BIAB'd and had some excellent beers.
I'm a bit unsure on the volumes of water to sparge with. I'll be aiming for 20l in the FV and will be using 4.65kg of grain. Aiming for a mash temperature of about 68 degrees. I'll be batch sparging.
According to the calculator on Jim's Beer Kit site I'll need the following.
Going to heat water to 75 degrees in HLT
Mash with 11.6 litres of liquor
Heat strike water to 85 degrees
First batch - 8.7l of liquor
Second batch - 13.6l of liquor
This should give me about 25l pre-boil taking into account dead space etc. I reckon I'll lose as much as 2l to dead space but still playing about with the mash tun.
The question I guess is why the different volumes for the 2 batches? Why not just add 11l to each batch?
Other than that does the above look OK?
Cheers, Ian
