When I ream my briar pipes, I notice some diminution of flavor. And when I clean out the shank (using a shank brush and alcohol), the diminution is much more noticeable. So I might conclude that much of the taste that comes from "ghosting" actually comes from the cake formed inside the shank of a briar pipe. Given that there's little or no chance of cake forming inside the shank of a metal-stemmed pipe, what does this imply for tasting? I'm thinking it probably means that smoking a tobacco blend in a metal-stemmed pipe such as a Falcon will probably taste closer to what one would get when smoking it in a non-caking pipe such as a meer or a cob. What do you think? What's your experience?
