This is a verbatim PM I sent to BeeGee. He has a theory, but isn't sure if it's the Right Answer, so I'm throwing this to the wolves....
I've been putting more and more thought into AG brewing, and one thing I don't understand is the iodine test.
I know the basics.... if iodine touches starch it turns black, so you use iodine to see if you have converted the starch to sugar. (right?)
If so, how the hell do you ever get a NON-black test result with efficiency under 100%? If you haven't converted all the starch to sugar, won't the iodine always turn black??
Remember.... I know jack **** about AG brewing, but this is something I've been wondering about.
