My efficiency was horrible last time, so I'm trying to nail down the best batch sparge process for next time. Last time I stirred in grain, let it rest for an hour untouched, then slowly drained a few pints, carefully added them back (trying not to disturb the grain), then drained the rest close to full speed. I added more sparge water, stirred well, waited 10 minutes, then repeated drain.
From what I've read about batch sparging, channelling is no longer an issue of concern since you're draining all of the water with each sparge. I read a post here somewhere talking about using aluminium foil on the top of the grain bed to poor the first few pints of runoff back onto to keep from disturbing the grain. I planned on adding this to my process next time, but now I'm wondering...
Do I care whether I disturb the grain or not?
If not, can/should I also stir the grain any during the initial rest?
