Re: Vegetable Glycerine...kills the flavour?
Glycerin itself doesn't add any flavor but instead adds more water content to the tobacco. If the your old Nakhla is dried out, then the glycerin will simply add some moisture back to the tobacco but not the flavor. As Mr.B said adding more glycerin without the flavoring means you'll be smoking glycerin.
