Morgy,
I don't know the ingredients or the recipe in total, but some flavors are more likely, others less certain.
There's definitely a tobacco of some kind---can't be sure what variety (burley, turkish, etc.), but I'm certain it's not virginia. Might be a blend of varieties that provides the baseline. I don't think tobacco absolute was used, however, because there's no ashiness. There's also a vanilla component, but I'm thinking more along the lines of vanilla custard with a just a smidgen of caramel or toffee to achieve that cake batter/cookie flavor. I'd also guess a sweetener---but probably not sucralose or ethyl maltol, more likely cotton candy, toasted marshmallow, or something similar that imparts a subtle flavor in addition to providing sweetness. If the sweetener were catalyn cream, that would contain cinnamon, which would explain your picking up that flavor. I can't taste any cinnamon at all, however, so I don't actually believe that catalyn cream is used. Other trace flavors may be in the recipe mix as well---perhaps something tangy or fruity in a very subtle way, such as just a tiny bit of lemon or even raspberry, but only a drop or two, sufficient to provide a little zing, but not enough to make your brain say "ah, tart fruit." Anyway, the flavors earlier in the paragraph are the elements my palate can identify.
The thing about Bounty Hunter is that besides the base ingredients, the rest of the flavors aren't used as flavors, per se, but rather as subtle tonalities that tease the palate rather than announcing plainly what they are. Bounty Hunter is very well-blended and unified, so that the ingredients function as a whole rather than as individual flavor components, which is a more common effect in most juice blends with multiple flavors. Nothing stands out in Bounty Hunter. Everything contributes to the smoothness---even the tobacco bite and very slight tangy zing end up adding to rather than disrupting the overall smoothness.
I don't claim that my palate is extraordinarily sensitive or uncannily accurate in deciphering flavors. Lord knows I could be wrong about what I imagine myself tasting. I do think on this one I'm in the ballpark, though.
