So my 2nd all-grain batch didn't exactly go as planned. My first AG batch two weeks ago I miscalculated and only got 6 gallons into the brewpot, and 4.5 into the fermenter. My efficiency calculated at 68%.

This week I thought I calculated the sparge better, and after two batch sparges I sent 6.5 gallons to the brewpot. I dunno if I boiled it like a madman or something, but I only got FOUR GALLONS into the fermenter. Could I really have boiled off 2.5 gallons in 80 minutes?

To make matters worse, the OG was only 1.051 on that 4 gallons, giving me an efficiency of only 58%. (BTW, I thought the crush from the supplier looked way too coarse. If I'd been a more experience brewer, I probably would have recalculated the hops back a little anticipating a low OG.) So I've ended up with an American Pale Ale with an OG of 1.051 (which is OK I guess) but a calculated IBU 76.6!

Maybe it's a good thing there are only 4 gallons of this stuff. Hold me and tell me it'll be OK.

Entirely possible, I'd say back off on the boil a bit.

I don't know about holding you, but I'm sure it will be ok.

I routinely boil off 2.5 gallons in the summer (60minute boil), If your pot is big enough you can adjust for it.

No, It's actually fairly low. I just try to keep a rolling boil. It was sort of breezy today so maybe that was part of it.

Also, I''m already seeing a really large amount of trub settling, more than I'd expect. I'll be lucky to get 3.25 gallons of clear beer out of this batch. Geez.

That "great tasting" part seems sort of unlikely at this point.

You know, 15 years ago when I used to brew extracts I routinely made 3 gallon batches. Of course, back then I did it on purpose.

I usually shoot for 7.5 gallons into the kettle, boil off 2 in 60 minutes, and get about 5.5 into the fermenter. I try to keep a nice rolling boil, nothing outrageous.

I've been getting a pretty similar experience too. I topped one off, without thinking and put the OG about 8 points below what I was shooting for. Guess my oktoberfest will have a bit less kick to it this year. Finished right on mark if that counts for anything.

What I have resulted with is collecting some extra off the lauter tun and adding it in later. It is expecially neccesary for me with recipies involving pilsner malt. I too would end up getting around 4.5 gallons if I let it go uncorrected for the whole 90 minutes. I collect an extra gallon or so usually and top it off right after the first hop addition at 60 minutes. I use a turkey fryer, and getting much more than 6.5 gallons in there is dicy at times. I make the addition right after the hops try to boil me over instead of before so as to have a little less volume to work with.
