I actually "borrowed" this process from another thread - weeks ago - but can no longer find the original poster.
Here is how I make my own coffee flavoring:
Take a 30 mL bottle and fill it about half full with fresh ground coffee. Whatever is your favorite. Fine ground is better than course.
Fill the rest of the bottle with plain pg. (Leave a little room at the top.)
Heat in microwave for 20 seconds. Let it cool down to room temp. Heat
