MY first AG went off without a hitch or hiccup. Shout out to Bobby M, used his tutorial and his suggested double sparge method. I made Ed Worts Kolsch. Brewers friend calculator shows 85.2% efficiency. Start to cleaned up took 5 hours with a 90 minute boil. All grain sure makes a longer day! I would like to thank all for their advice and wisdom. It is amazing how much information is on this site.
