I noticed that when you enter a grain there is a little streamer below it with ppg etc. I know that ppg is the max points per pound per gallon and than deg L is related to color, and dp it diastatic power relating to proteins. My question(s) is/are: how do you calculate the pts and OG and what exactly are they? Also, is there a spreadsheet that has that info for the grains you have in the dropdown? I'm adding grains in a dropdown that will return ppg and deg L using vlookup and I'd like to not have to type it in each time. In other words can you share that with me?
