Dear Ms. Aileen:
Thank you for asking! In the famous words of some guy I don’t know:
No coffee can be good in the mouth that does not first send a sweet offering of odor to the nostrils. ~Henry Ward Beecher
There seems to be only a small group of components that are responsible for your experiences of those wonderful java aromas, but it is their high level of concentration that makes the aromas so distinct. After you inhale the conventional way, a retronasal perception kicks in. This takes place in the nasal passage during the time the coffee is in the mouth or just after swallowing it. So, it seems the experience begins when you hear that beep of the coffee pot signaling that the brew is ready and the scent is filling up the kitchen – and lasts until the last drop! Walk over to that coffee pot (don’t even say the word ‘instant’) and breathe in that freshly brewed aroma. Let’s inhale together….ahhh. Now pour. Hear that smooth liquid splash against the cup? Sprinkle a bit of Irish Cream flavor, and lift the cup to your nose. Ummmmm.
