I don't exactly know myself, it just is. Maybe it has something to do with the corn essence and burley mixing together. Some people say that they get a "buttery" taste from the combo. I have never really got a buttery taste but it definitely enhances the flavor of whatever burley blend I'm smoking. Sometimes I'll get a little more nuttiness or sometimes it will be a little more creamy, depends on the blend.Davey":d4iu7hyx said:still wondering what is the majic with cob and Burley?
