So after a little over a year of brewing with LME I decided to switch/expand over to all grain. I’ve already done one batch a couple weeks ago but not wanting to wait over a month to sample the product I decided to brew a second batch.
Both times everything went smoothly and no issues to really speak of. In fact I had a buddy over and I think he now will be converting from the LME method to all grain.
I’m looking for a little confirmation that my Efficiency calculation is correct, in my rush the first batch I did not record my readings
Heres what I used/recorded
1.5lbs crystal 75
Mashed with 3.83 gallons at 152F for 60 minutes, collected about 1.8 gallons and sparged with 5.5 gallons to get a total of 7.3 gallons pre-boil.
7.3 gallons at 140F, took an hydrometer reading of 1.029 converted to account for the higher timp to get a true reading of 1.044.
So using an online calculator I’de input
Pre-boil Gravity 1.044
2-row, 10lbs fermentable 1
Crystal 75, 1.5lbs fermentable 2
Pre-boil wort amt 7.3gal
To get an efficiency of 74.52%, and 27.93 points/pound
???????? ok I think I did it all correctly, now the only question is 74.52% a good number or bad? In school 70% usually got me a talking from the parrents about not living up to my potential are C's in beer brewing bad??
