It's not very necessary to pipe smoking enjoyment and perhaps overrated.
Well, as the culprit here, I respectfully disagree. Now mind you, my experience is somewhat limited. I've only been smoking a pipe for the better part of 40 years. But, despite that lack of practical experience and practice, I'm quite sure regarding what I am experiencing. Flavor is a product of both taste
and aroma. Try plugging your nose and eating a food, then try the same food with when you have the ability to smell its aroma. The experience is quite different and generally you experience greater flavor. Anyone who has had a severe head cold knows that their sense of "taste" of the foods that they eat is diminished.
I am an outdoor smoker. The only time that I smoke indoors is at a pipe club meeting or when attending a show. So I'm not sitting in a room in an aromatic cloud of smoke. As an outdoor smoker I can't rely on the room to provide me with part of the flavor profile. Indoors, you are getting some of your flavor from that aromatic cloud of smoke around you. You're inhaling the smoke when you breathe in and smelling its aroma along with what you taste in your mouth.
Being an outdoor smoker also means that I've had to experiment with drying times and preparation to find out when a blend will provide me with the most intense taste. No help from the room and the cloud.
Outdoors, I get the aromatic part of the flavor profile from smelling the smoke as I expel it. No static smoke cloud to inhale through my schnoz. And even on those few occasions when I do smoke indoors, my experience of the flavors in the blend I'm smoking is further enhanced when I retrohale. I also get the occasional benefit of not having to smell some other guys choice of skunk weed.
Outdoors, the difference in the extent of what I experience in flavor when I expel the smoke through my nose is profound.
But if you wish to persevere,sip some smoke, close your throat and exhale through your nose.
Keep in mind that your taste buds are not in your nose or lungs however.
But your taste buds are only part of the receptors that allow you to sense flavor. Your olfactive sensors are in your nose and they contribute mightily to what you experience as flavor.
