That's actually an extremely hard question to answer - and you would have to be a qualified chemist to create the flavor concentrate(s) needed. However, to really sum it up in an
as condensed form as possible: A flavorist (chemist) would create a flavor by combining certain known chemicals; that act as purely the flavoring for common food items and not the nutrition itself, together to create another flavor. If you've ever taken a high school chemistry course, perhaps you'll understand a little bit better with the following. One of the base chemicals in say; Banana for example, would be isoamyl acetate (CH3COOC5H11). This chemical is not achieved by any simple means of just breaking down a banana, but rather creating the chemical itself with the desired mixture of existing chemicals.
As of now, most known flavors (flavors that exist in nature) have been recreated with this method. It is rare that a new flavor is discovered, but does happen. So when I say that we are looking to expand our flavors, what I mean is that we will try to find a vendor/manufacture of the flavor concentrate so that we may mix it with VG, PG, and Nicotine for our customers. Unfortunately, nobody here is qualified to make our own flavor concentrates. Keep in mind that concentrates and extracts
ARE different, with extracts only containing a small amount of flavor - whereas concentrates are much stronger and able to be used/mixed with
ejuice.
Hope that sums it up for you!
