I've found a couple of recipes for dry artisanal meads that call for batch sparging at 148 F for 75 minutes. This recipe was created with BrewSmith software and maybe this step was thrown in by the app, but I'm confused about this step.
To summarize the step directions: 6.2 gallons sparge volume at 148 F for 75 minutes. (The next step is to transfer the must to the primary fermenter and cool to 80 F and pitch the yeast starter.)
First, what's the purpose of this sparging? I think I understand the basics of sparging with an all-grain beer, but what good is sparging for a mead in which the only sugar source is honey? Is it just to make sure that all the honey is dissolved in the water. The sugars have already been broken down to simple monosaccharides by the bees, but is there further breakdown needed?
Second, the total "boil" volume is 6.25 gallons (5 gallons of water and 1.25 gallons (12.8 lbs) of honey. Then a subsequent step (after the mash) is to add water to the fermenter to total 5 gallons. What happened to the other 1.25 gallons, and why would one need to add more water? Is it to be used for topping off in a subsequent fermentation phase?
Thanks.
