Yea it seems like it works pretty well to get all the sugars out of the grain. I don't really stir the wort in the boil, I just let the boil move things around... I just use the mixer before my first and second runs to make sure I get all the sugars.

So I thought since I batch sparge the grain agitation is really important to extract as much starches as possible. So last batch I used a Paint mixer on a drill and it worked superbly. Just wondering if I'm the first one that's ever used this method, and what you're inputs would be.
