Did my first AG yesterday.
The good: mash ph was right on @ 5.2, I hit my mash temp on the button and stayed there for the whole mash, My homemade mash tun didnt clog! Airlock bubbling happily 10 hours after pitching.
The bad: Brewed outside in teens temps. Regulator on propane froze up and i couldnt get good psi...had to switch to stove top.
The ugly: 57% effeciency...boo! I only mashed for 60 as opposed to the reccomended 75min on the recipe. My OG came up wayyyy short so i had to boil off and add some table sugar. Only wound up with 4 out of 5 gallons.
My question to you all: Was the short mash likely the cause for the low gravity? My crush was good, even borderline shredded. I can upload pics of the tun and gravity numbers if you wish!
