 Water:

Final beer volume: 18 l

Fermenter target: 19 l (trub loss 1 l)

Kettle post-boil Volume: 23 l (sediment loss 4 l)

Kettle Pre-boil volume: 26 l (evaporation 3 l/hour)

Assume 1.25 l/kg absorption: A = 10.75 l

Strike Water: R=Mash @ 3 l/kg: B = 25.8 l

First wort volume: B – A = C = 15.05 l

Sparge water @ 75 ºC: 26 – C = D = 10.95 l

Strike water temp= (0.41/R) x (T2-T1) + T2

                            = (0.41/3) x (T2-T1) + T2

                        = (0.136’) x (69 –      ) + 69

T1 = Current ambient Temperature
