I was trying to mash/sparge ending up with 6 gallons of wort to compensate for evaporation in the boil.
I've just run out of sparge water leaving me with 5 gallons of wort. I don't really want to dilute the wort after the boil, so can I just add water as it boils off? Surely only the water will evaporate anyway? and as my SG of the 5-gallons I collected is reasonably on target, it shouldn't matter, right?
Is there any reason why I should worry about adding water to the boil to compensate for evaporation?
