Default need hekp with my first all grain brew

So today I brewed my first all grain batch, and my preboil volume ended up at 7.2 gallons instead of 6.5. My pre gravity OG was 39 instead of 55, so will I be OK boiling down to 5 gallons or should I add some extract to make up the difference?

Boil until you hit 6.5 gallons and then start your hop additions and 60 minute boil from there.

You're likely to get some input from some brewers with more experience than I at all grain, but until they chime in, I'd say to not fret about being off on the preboil volume one bit.

Just boil that sucker down to 5.5gal or whatever your mark is to start your hop additions and final 1hr boil, and go from there! I'm not even sure why you're trying to take OG readings at this point anyway, though I don't usually calculate out all the efficiency numbers like I know many do.

I'd definitely think long and hard (and be sure I had a damn good reason) before adding any extract. Before you do anything, though, get down to your 5.5gallons and reassess then before starting in on your final 1hr boil.

If he boils all the way down to 5.5 gallons and then boils for another hour he'll only end up with 4.5 gallons more or less... I think it would be more wise for him to boil to his original pre-boil amount of 6.5 that was intended. Then take a gravity reading and see if it's closer to the pre-boil gravity that was expected...

Not sure how to quote on my phone but...

I took a gravity reading pre boil because this is my first all grain brew and I wanted to see how I measured up to Beersmith. I came in low, but the advice to be real patient before adding extract is a good one. Being my first all grain, I think I'll take my chances and see how it turns out. I'm not ready to admit defeat this early!

I'm going to boil down and cool a sample to see what I get to. If it's a low alcohol brew, so what?

Also, how can I improve next time? I hit my temp at 158 for the mash, and had a nice clear sparge. It only took 30 minutes though, can I get better efficiency by going slower? 12 pounds of grain for a five gallon batch BTW.

So I took the advice and I guess I wasn't as bad as I thought; I came in at 52 instead of 62, but that's ok... thanks for the help guys! I'm cooling down now and will let this turn out how it will.

Knowing the type of beer and recipe would be useful, but in general, mashing at 158 is a bit on the high side and could affect your efficiency. Your grain crush may also be a factor.

Sparge: Fly sparge with 4.46 gal water at 168.0 F
Notes:
------



Looking back on my notes and my brewday in general, I think the culprit might have been me. Just got a new setup for all grain, it includes a fly sparge with a ball valve. I checked on the sparge a couple times but I only had like a half inch of water on top of the grain bed if that. So I'm thinking maybe the water really only washed a part of the bed instead of the whole thing. Will the sparge water circulate through the grains or just flow down one path?
