I've brewed probably a dozen beers all with extracts. But I've never had one have an OG this high! This is a chocolate peanut butter beer so I'm wondering if it's just so thick that it's holding the hydrometer up or if there really is that much fermentable sugar in the beer. Any ideas would be appreciated. Here's a quick list of what I used,

1 lb various grains, steeped for 30 min.
12lb dark malt extract (yes, 12 lbs)
33.5 oz PB2
8 oz Organic Cocoa

Thanks again.

I'm assuming this is a 5 gallon batch? Did you stir this completely? If it wasn't stirred well you could be measuring high.

You're measuring specific gravity when you use a hydrometer not just sugar content, so when you add dense materials to your recipe the gravity will go up. That being said to figure out your gravity, I'd probably figure out the sugar and carbs in PB2 and add that to the value your malt extract gives you.

dense soluable material, things that sink or float shouldn't effect your gravity. But Dryboroughbrewing is right, getting the carbs/sugars per serving of the Cocoa and PB and normalize to the amount added and then to the dme should give you the sugar content for ABV purposes.

For instance, the DME has about 45 points per pound gallon - in your case 540 points/5 gallons would be an OG of 108.

So now you'd look at the PB and find it has 5gr sugar per 1 oz serving for about 165gr for what you have. Convert that to points (about 15ppg) and add that to your numbers above (either 540+15 or 108+3) - Note I'm making up the 5gr/1oz serving check labels.

The rest of your gravity is a combination of dense protien, and poorly mixed wort from the top off.

I will get he measurements of the DME, PB2 and cocoa. Are those the only items I'll need? They should be the only things with any fermentable sugars in them right?

Thanks again.

You're correct floating or sinking materials will not have an effect. However, dense soluble materials certainly will as you're measuring the density of the solution.

How do you know it is over 1.2?

I've never seen a brewers hydrometer that reads anything like that high.

IMO you did not get a very good mix of wort and top off water coupled with the density of the added ingredients is causing a false and ridiculously high reading.

I have a ignorant question. Is doing the calculation on paper (like above) close enough compared to taking the hydrometer OG reading? Also why not just do it all on paper (OG & FG) and get rid of the hydrometer?

@ AFJ: My mistake. 1.024. Still, pretty damn high.
@duboman: I actually don't add top off water. I have a 10 gallon brew kettle so I'm able to do it all at once. And I mixed it well before taking a reading too.
