I'm brewing an oatmeal stout tomorrow and have had sporadic efficiency numbers from my last 6 brews. 5 out of my last 6 all grains have had a preboil reading of at least .010 less than where they needed to be. This time around I'm preparing by having some DME handy in case I don't hit my numbers. Just wondering what the math is for how much DME is worth to gravity points. So say I'm shooting for a preboil of 1.065 and I hit 1.055, I would use ______ cups of DME.

1 pound of DME in a gallon will give you about 1.040 gravity reading.

Okay. I'm looking at about 8.2 gallons in my preboil. What would 0.10 equate to in the amount I would need for DME?

Hypothetically, 2 lbs should give you .00975 in 8.2 gallons. If my math is right

That is assuming you meant 1.010.
