I taste for a living. Everything that goes into your mouth, or near enough to it, that has enough volatiles to create an aroma will enhance a tasting experience. Without the sensory receptors in your retro nasal chamber you would rely on taste buds on your tongue for discernment: essentially leaving you with sweet, sour, salt, bitter and umami. To graduate from tastes to flavour you’ll need the nose. You will get aromatic impression from smoking orally. You will also get aromatic impression from a retrohale. I often retrohale when smoking a pipe; I never do when smoking a cigar. No one has ever told me that I had to retrohale at all. It’s one of the many facets of this hobby that is entirely a personal choice.
