Mouth aroma
The fumes you taste in your mouth when consuming food. You can usually taste it best when breathing in your own mouth.
I was eating steak when I realized the mouth aroma had a peanuty flavor.
Mouth Aromas
When you have something in your mouth and even if your nose is closed you still can taste the smell. (I.e gases)
Example: “yo bro when I put this martini in my mouth and close my nose I can taste the mouth aromas.”
