Now to calculate the sparge water so that the volume of wort in the boiler is the same as our calculated preboil volume.
Therefore, 28 L (7.4 US Gal) is the preboil volume we want then:
Preboil Volume – Mash Water + (Grain Weight x Grain Absorption) = Sparge Volume (Daniels, 1996)
28L – 17 L + ( 5kg x 0.8 L/kg) = 15 L
As with the mash water, the same assumptions of measuring and heating the sparge water apply due to thermal expansion. This especially applies when measuring the preboil volume. If your sparge vessel has a dead space where the water cannot be recovered, most hot water urns can be manually emptied by tipping the remaining contents into the grain basket. But if you cannot recover the volume this volume will need to be added to the sparge volume.
