Active fermentation is still bubbling away, so I'm not worried about the finished product. I'm sure it'll be fine and taste good. I just want to hit my high grav numbers when that's what I'm shooting for. My low grav beers typically come put pretty close to target.

By the time you start putting 18 pounds of grain into a tun you're going to be seeing diminishing returns. I've had similar problems getting above 1.070 and the second plot on that thread shows the downward slope of efficiency with more grain.

At that point maybe you should consider a partial mash? Make up the recipe as normal but then convert a fraction of the grain bill (base malt, etc.) to DME/LME so you are mashing in a 'smaller beer' so you can retain the higher efficiency.

That occurred to me a couple days ago.

Try adding a couple oz of Acidulated malt to drive the mash PH down. My efficiency improves markedly

If you know your boil off rate, you could sparge a bit more and calculate when there are " 60 minutes left in the boil" and then add your hops. If this suggestion has already been made, I apologize.

Well, with over 86% attenuation so far it's at 8.5% ABV and the sample tasted dry. Time to start dry-hopping and then rack & cold-crash after I get the Schwartzbier out of the ferm chamber on Sunday. Can't complain.

Do you check your mash ph?
are u sure your volumes are correct?
I found that once adjusted my ph due to having high alkalinity, my efficiency shot up, i brew using the full volume no sparge method and always hit 72% - 74% and the only thing i can put it down to is ph.
Also with brewers friend, remember, that when you enter your batch volume you need to enter it as the volume in your kettle and not your fermenter, as this will show as an efficiency drop.
For mine i enter 26 litres even though im aiming for 23 in the ferm, as i lose 3 litres due to kettle dead space.
Hope that makes sense
