Calculating Efficiency?

[moetman]

HI - I've heard a lot of people talk about Calculating the "Efficency" of their wort - I assume this means the amount of sugar you extract in the mash? Could someone please tell me how you calculate it?

Regards

Palmer goes into a good amount of detail here

Most programmes, such as beersmith, promash, etc will calculate it for you, bit its good to know how its done, so you can calculate for different parts of the process (usually for troubleshooting).

EDIT: I had a spreadsheet that uses palmers calculations, and converts to metric weights and volumes. Its in this post here
But as with any efficiency calculation, you will need to know the potentials of the ingredients. The JW and Weyerman specs are on the sheet.
