I brewed a partial mash recipes using BIAB method last weekend. I mashed all my grains and then added LME in the last 15 minutes of the boil.
I tried calculating my efficiency using Brewer's Friend (https://www.brewersfriend.com/brewhouse-efficiency/). I am coming up with 57.4% efficiency (not great) based on my readings after pulling the bag at the end of the mash. I am coming up with 34.4% efficiency based on my readings going into the fermenter. Is this normal to see a drop in efficiency between these two readings?
Does anyone have any insight into how to read the analysis sheet for a can of LME? I would like to run the calculation by hand to verify the 34.4% efficiency.
Readings at the end of mash: V=3.0 gallons, SG=1.037 (measured with refractometer)
Readings going into the fermenter: V=5.0 gallons, SG=1.038 (measured with hydrometer)
My grain bill is:
4.00 lbs Pale 2 Row
0.50 lbs Caramel 20
0.50 lbs Aurora Mills Spelt
0.25 lbs Cara-Pils
3.3 lbs Briess CBW Golden Light (http://www.brewingwithbriess.com/Assets/PDFs/Briess_PISB_CBWGoldenLightLME.pdf)
I believe the LME was stirred in well (none burned to the bottom of the kettle)
