Yet you come here taking issue with the procedures by those that have done extensive research?I admit the science of how PH is measured isn't my area of expertise. That said, I do know that when it comes to brewing, it's the PH of my mash AS IT'S TAKING PLACE that is important. Personally, I don't even measure it. I take experts advice and use my water parameters and grain bill to estimate it. Since adopting this practice my efficiency, and most importantly my beer, has been excellent.
I enjoy learning about beer, but I have to draw the line when someone is trying to dissect something down to a level that can't possibly help me make better beer. I guess my final thought is, WHO CARES!!!
