Are you using a brewing software? If yes, which one?

Mashing times are always 60 min.
What changes can I make (other than always mashing at around 160 F) to INCREASE efficiency but DECREASE fermentability?
Incorrectly setting up your brewing software will show you have an eff. of 65%, when you may actually have 78% eff.Crushing your own grain? If yes, what's your gap setting?
Crush quality has a profound impact on your eff. and gravity numbers.Is your mash tun isolated?
You have been mashing at 160* but getting too much fermentation (low final gravity) and you have a good thermometer. I would say your mash tun is losing heat. I use an isolated igloo cooler, if I single infuse a mash...temp drops 1* in 45 minutes.Do you "preheat" your cooler?
I pour about 2 1/2 gallons of boiling water into mine, cover, and let sit for a good 20 minutes to preheat. If your not preheating, your mash heat is being lost into the cooler itself. Bringing your 160* mash down to around 145*...a very fermentable beer.
