All-Grain experts, I recently built a cynlinder cooler mash tun (10 gallon) and started All grain. But I have been having problems getting all the projected sugars out of my grain.
I followed a recipe for a saison that would have gotten me 1.066 OG, but instead I got 10.52.
The cooler I use is a rubbermaid 10 gallon, I use a mesh tube to filter.
I mashed in at 153 when 154 was called for and after stirring, I noticed a temperature drop of 5 degrees., I mashed for 60 minutes, did an iodine test that showed Sac was occuring, not many starches.
Batch sparged at about 168 degrees for 15 minutes and collected about 7 gallons total.
What am I missing here? Am I doing something wrong in the process? Is my equipment to blame? Should I not stir much during the 60 minutes to keep temperature steady?
I have been reading John Palmer's book, watching videos, checking out Denny's notes to make sure I am not missing a step, but it seems like I am.
Thanks for your help and guidance.
