Finally got back to brewing now that the rainwater tanks have filled up a bit.
I'm still working out Beersmith for the Braumeister.
When I print out the brew steps it says total water needed: 35.21
Lower down the page it says Mash in 25.61 then after all the rests it say to batch sparge with 15.21l of water.
This doesn't seem to add up.
Any suggestions to what I'm doing wrong?
