The head space should not be an issue, but what happened?
I didn't grind the grains, they came pre ground from Northern Brew. My mash tun is a 10 gallon igloo cooler with a stainless steel hose for my filter.
Well, the boil was supposed to have been 60 min, but I boiled for 110 min.
Grain bill was:
11 lbs. Rahr 2-Row
1 lbs. Briess Caramel 40--
0.75 oz. Centennial (60 min)
-- 1 oz. Centennial (20 min)
-- 2 oz. Centennial (5 min)
My mash went PERFECT! I held it at 152 for the full 60 min. I vorlofed, mashed out, and did a one step batch sparge with 3.25 gallons. I mixed well before I drained.
I took my Preboil reading, and it came out to 1.034, and was supposed to have been 1.050. Sooooo, I panicked and decided to boil longer, and add a pound of DME. I was supposed to wrap up at 1.064, but came in at 1.055. And, only 3 gallons in the fermentor. I cannot believe just a poor grind is to blame? What else did I do wrong here? This is only my second all grain batch, so I am really not sure what I did or didnt do. I do know that I did a good job on the mash temps. I pretty much went with what beersmith told me to do, from water volumes to temps.
Well, at least I have 3 gallons... I just hope its not over hopped. I did not adjust the hops at all to compensate for the boil off. Good thing Im a hop head I guess. Any suggestions as to what may have gone wrong and what I can do to dial this in any better next time? I do know that I am going to buy a grain mill.
