Having done about 6-7 brews now on my GF, I was a bit disappointed with my efficiency and what appeared to be pretty stuck mashes and sparges. This weekend I took a different approach and gave the grains a good stir after 10 mins of mashing and again after about half an hour. What a difference! Efficiency through the roof, everything draining nice and smoothly (not quickly, just evenly), and the clearest wort I've had to date. This seems to go against all the instructions and demo videos out there but I'll certainly be employing it in future brews. Just wondering if anyone else has tried this or has any suggestions as to why I'm having to do it in the first place? I do use a handful or so of oat husks to try to loosen up my grains and I have them crushed when I buy them from Malt Miller (they don't appear too fine).
