Hey all.
I apologize, I know efficiency is one of those topics that has been extensively covered, explained, etc. I have a situation that I haven't seen brought up in my readings.
The short:
I have 8 all grain batches under my belt. On every one of those batches, my post boil gravity has been 1.053-1.057.
The odd part:
The estimated post boil gravity of the recipes have been more widely varied. No matter what the grist, I end up with the same post boil gravity. This puts my %'s all over the place, from 50% to 70% at best.
Background:
Full volume, no sparge, single 60 minute infusion at 154-156, eBIAB, Bag Squeezer.
Grains bought pre-crushed from Brewmasters Warehouse.
Grist have been from 10lbs to 18lbs with mostly dark beers.
Using generic spring water from Stop and Shop without any chemical alterations.
Yesterday, I tried mashing out with no additional points to post boil SG.
--------------------------------------------------------------------
I know I should relax, which I am. I know I shouldn't chase efficiency, which I am. I'm going to look into water chemistry as my next course of study.
This is the fun part. Looking at perceived problems, and trying to solve them.
So...any ideas on how to improve extraction? Step mashing? grinding my own grain? 90 min mash (tried once, no difference)?
