Still, I think the idea is not completely worthless.
Out of curiosity I would suggest a rather more rigorous experiment. Maybe sometime I will run it myself.
I understand that in a closed vessel at a certain temp all spice will turn into vapor. If the vessel walls are kept at the same high constant temp the spice will stay in gaseous state for a long time. Thus the experimenter will be able to inhale it at the lowest possible temp. At the same time condensation will be insignificant.
Not only water baths but even oil baths may prove insufficient, so the idea would be to drill a hole in a block of aluminum wide enough to accomodate a test tube and deep enough to cover 2/3 of the tube. Another hole will be made to insert a thermometer. Heat source is not that important but it should be easily controlled. Such an experiment will resolve the issue of optimal spice vapor temp once and for all.
Do not seek the truth, just drop your opinions.
