Perhaps this can help some members: I have a lot of StBernard’s Flake (see earlier post above), I found that after a year or more in the jar it becomes very sweet and not in a great way. Becomes muted, loses a lot of nuance in my experience, loses zing. By comparison, in the same timeframe StJames Flake also becomes sweeter but seems to hold the Perique spice better. Pain in the ass tobacco that it is, StJames Flake may be the best VaPer for me.
Edit: I see I’d already posted the change over time! Well at least I am consistent!
