Sometimes, it's just the way the tobacco quality is. I know a few blends that burn hot no matter what, both harsh on the palette and harsh on your pipes. They are not blends that I smoke, even though some of them may taste decent. This is regardless of dry time and cadence. I don't consider these blends of tobacco to be quality. Quality, smooth tobacco has a lot to do with how it is sweated and processed. Also, it has a lot to do with how it is cased. Some blends are just down right harsh and hot burning to me. You won't find this is in Gawith, C&D, Pease, Germain, and Peterson/Dunhill blends unless it is user error.
