Thanks! Yeah, distillery, mashbill, char all seem to be best guess sort of information. I agree, collecting the data has been more helpful than its analysis so far. The biggest thing I learned from running the numbers was that I seem to like expensive whiskey the most
Well, it's not perfectly linear, but age probably correlates with expense more than anything else. There's a thread around here somewhere that includes the mash of most major brands and the char level for most of them.
