I'm still brand new to pipe smoking, which will soon be abundantly obvious. As I have been reading through various threads and posts I have seen such sayings as a "sweet smoking pipe" and a "pipe break in period" or even a getting pipes to "mellow out." What am I missing here? I know that you have to form a cake, or not depending on where you stand on bowl cake. But what does it mean to have a sweet smoking pipe? Forgive my naivety on this subject.
