Dense Wort Pocket Throwing Readinds?

So just finished my first partial boil partial mash.....and of course my OG is waaaay too high.

I should be looking at an OG of 1.053 at 5 gal. Instead, I have something in the 1.066-68 range. I even attempted to filter my sample through a coffee filter to get out any sort of residual hops that may be throwing the reading. Temp was 68.


My brew math.

After mash I had around 3.6 gallons of mash showing a gravity of 1.031. My calcs showed at 3.6 gallons I was at 111 points. Looking for a total of 265 points, I added 154 points worth of DME, or 3.5 lbs.

After topping off to a final volume of 5 gallons and shaking the fermenter, I took 3 readings back to back, with the last one going through the filter.

I am hoping this is just another reason to up my gear with a 10gal for full boil. But if I did something wrong, I would love to get schooled. Thank god I made a starter.

Time to drown my sorrows in an old rasputin.

This was my first go around with a PM BIAB, and I ended up with about 52% efficiency. Not the greatest I know.

I am assuming that is what you are referring to.

I think you simply added too much extract. Perhaps I'm misunderstanding your process, but 3.5 lbs of DME in 3.6 gallons is somewhere between 1.030 and 1.040, depending on the extract. So it's not surprising that you ended up with 1.066 or 1.068 after adding it to wort that was already 1.031 after mashing.

- Just noticed it was a 5 gallon bath. So I assume you added water, too. I would need to know more about your process to figure it out. -

GOOD GOD MAN!!!

What are you doing typing?????

Get a large burlap sack, a few hundred beers, and update us on Monday.

Yes, this was a partial boil and I topped off with around an additional 2 gallons of water.

MY recipe is posted below. I was essentially looking for 265 points for a 3.5 gallon batch, so that after topping off, 5 gallons should have looked a lot more like 1.052. After mash I was looking at 1.031, and added in 3.5 lbs of DME @ 20 minutes left in the boil. I don't understand how after all was said and done, 265 points in a 5 gallon volume doesn't end up giving me a gravity of 1.053.

Your help is greatly appreciated!
