Default Basic Efficency Question

OK, I'm an AG newby who has no brewing software or anything like that. So, what's the formula or "best way" to determine mash efficiency?

Use promash or another equivalent brewing program.

Honestly, it is pretty easy, you add the gravity points of your fermentables and figure that to your actual OG. It is hard to explain but pretty easy to figure. I'll see if I can find a good reference.

I've always used a brewing program of some sort and I now depend on ProMash. It is probably a good idea to learn the actual math so you understand what is going on. Having said that..... I think I'll stick with ProMash.

First, you add up the potential points/pound/gallon of your fermentables. This requires a chart. Then you divide the total points by the volume of wort. That is compared to the measured gravity.

A very simple example:

10 lbs 2-row pale @ 38 PPG
5 gallons of wort

That's 380 point/5 gallons = 76 points and a gravity of 1.076

If your measured gravity is 1.053, then your efficiency is 53/76 or 70%

Every grain has a different PPG and most brews use 3-5 grains.

See why we use software?
