## GFWtr - Grainfather Water Calculator
Asks for the batchvolume in l (Aussschlahmenge / Asslg) and grainbill in kg (Malz) and
calculates the amount of mash- and sparge-water for grain bills > 4,5 kg according to
this formula from the Grainfather manual:
```
MashWater = GB * 2.7 + 3.5
SpargeWater = (BV + WL) - MashWater + (GB * 0.8)
```
GB: Grainbill in kg
BV: Batchvolume in l
WL: Waterloss in boil & trub in l (defaults to 5)
Adjust waterloss in line 10
