I need help, I just brewed a stout using the BIABicus software and I was told that I ended up with aprox 62% efficiency and I'm not sure why. I filled everything out as I should. I started with the same amount of water, I double crushed my grains using the finest setting on the LHBS mill. I mashed @152+or-2 degrees for 90 min. It was cooler outside and it was fairly windy, granted the lid was on and I had the MT covered with a heavy blanket. I boiled with a rolling boil for 90 min, my evap was as predicted....I'm not sure what else to do. I didn't change the water or adjust the PH. I did recently ask the head brewer at a local brewery what they did to the water and they told me nothing but cold filter. Any help would be appreciated.
Also, I have been getting the same efficiencies for the last few brews and for the record this is my 5th beer using this type of brewing and I did score a 28 on my first entry to a home brew competition so I know I can make ok beer.
