How To Compute Efficiency

[KIDD]

I am new to all Grain and was wondering if someone could walk me through calculating efficiency. I am brewing 10 gallons and using a 48 qt rubbermaid cooler, with a cpvc manifold. Thanks in advance.

By the way I batch sparge.

Here is a thread with some info for you. ESPY has what you are looking for in post 5. Most people just use ProMash or BeerSmith to get their numbers, also Ray Daniels book Designing Great Beers has that info.

I have a site and this is the formula I use to calculate the Brewhouse Efficiency... I know the gravity of the grain I put down is wrong but it's just a quick example on how to use the formula. You can find this site at LS_Grimmy's Beer Math

Hope this helps

Brewhouse Efficiency:

((Original Gravity x 1000) -1000) / (Total Gravity points / Mash Volume in Gallons) = BH Efficiency

Here is an example with an Original Gravity of 1.040 and the following grain bill.

10 lbs 2 Row x 23.4 Gravity Points = 234

1 lb Crystal 40 x 21.5 Gravity Points = 21.5

Total Gravity points = 234 + 21.5 = 255.5

After we have our Total Gravity Points we can now finish our brewhouse efficiency calculation...

((1.040 x 1000) -1000) / (255.5 / 5) = 0.78 or 78%

Actually, I think my post had what you were looking for.

Read JP's ch 12-3 through 12-5. http://www.howtobrew.com/section2/chapter12-3.html


Then read the rest of his book!

Thanks guys. i calculated 72 % E using the calculator for our first Pale Ale.

Does it really matter who gives him the info

Does it really matter who gives him the info Mango...

Huh?

Where is this hostility coming from?

 

[Lil' Sparky]

I think that was aimed at me, and I was just being cheeky. Sounds like the Grimmster needs a homebrew.

 

[LS_Grimmy]

Sorry Mango my bad... as recommended the Grimmster got a few homebrew in him and all is good

Cheers guys,
