Or is this another mantra that is repeated because it was read somewhere?
It used to be said that the gap should be 0.040 or you risk tannin extraction, but now people are going tighter for more efficiency and no reports of tannins.
It used to be that the hottest water used for sparging was 170, batch or fly, or you risk tannin extraction, but now we know that batch sparging can go much hotter.
Is this another one of those? or is there something to it? I'm not proposing they be run at 1500 rpm off a direct drive of a furnace motor, but my crappy cordless drill probably runs the mill at 600 rpm with the trigger pinned.
Cheers
