What's my efficiency?
So I'm a new AG brewer, I previously brewed with extracts, but that was over 10 years ago, and never made anything very good. I just competed my AG brew a few months ago, and it is fabulous! I'm shocked at how good it turned out. I've brewed a few times since and my efficiency doesn't seem to be what it should.
I just finished my Tangerine Wheat, and had a 12 lb grain bill, but only ended up with a pre-boil SG of 1.040 (first runnings 1.040 2.9 gal, second runnings 3.5 gal @1.020). Single batch sparge, and I'm using all the tricks. Stir the mash well, good mash temp 154 and even throughout the tun. I'm slowly draining the mash and the sparge, < 1 liter/ min. Strike water 190 degrees, calibrated thermometer, ph 5.0, stir the mash occasionally during mash period. Using 1.5 liter per pound for mash volume.
Just don't know why the SG is so low. I'm using the 10 gallon Home Depot round cooler with a bazooka screen. I would appreciate any help! I'm thinking of switching to fly sparging to see if that helps.
Also how do I calculate my current efficiency 12lbs for 6.5 gallon boil at 1.040
