I'm no atheist scientist, but...
So, since I just bought a new 58 quart mash tun, I figured I'd break it in by doing a parti-gyle RIS and dry stout.
so, here's my plan. I am gonna do r2eng's Double-W RIS (https://www.homebrewtalk.com/f68/double-w-imperial-stout-74932/), but dough-in with enough water to get pre-boil volume. So, dough in with about 11.5 gallons (11.5 - 3.5 grain absorption = 8gal preboil, 90 min boil), drain that off, then add another 8 or so gallons of water to the mash to get another 7 - 7.5 gallons of water for the small(er) beer.
Does this seem reasonable? What do you think my efficiency drop will be for essentionally no-sparging the main RIS? Should I add a few more lb of maris otter to make up the difference?
