Hi all,
In another thread I was enlightened to the proper way of calculating Conversion Efficiency as described on Braukaiser here: Understanding Efficiency - German brewing and more (braukaiser.com)
I normally only take a gravity reading when I transfer to my Fermenter, but today I was making a Session IPA for my better half and took a gravity reading before boil. I plugged-in the numbers and get 95%. I did sparge with a little water and did include the water volume into the Braukaiser equation. I also squeezed the hell out of the bag as usual by putting all my weight on it (picture of my set-up from a different brew day is below). I realize this is not Conversion Efficiency, but Mash Efficiency since this is pre-boil and I included the sparge water.
Since this was a BIAB Session IPA , the mash was quite thin and according to doug293cz's chart (Lauter Efficiency) I should have done pretty well. 95% seems a bit too high for me though for a Mash Efficiency. Here are the details to the brew:
Water:
36 Litres
Grist:
2 kg of Vienna DBCG 79% 4%MC
2.5 kg of Golden Promise 306 IoB HWA, 2.5% MC
No special milling apart from the "crushed" malt I always get from my brewshop.
Pre-Boil Gravity:
1.032 @ 24.9C (1.033 adjusted)
My question being... should I be happy, or should I be scratching my head?
