There's a progression in the wine world that leads in a non-linear way from the most mainstream to the most esoteric. There are far too many forks along the way to connect the two but what one can say is that what is one day esoteric may very well be quite mainstream the next, metaphorically speaking.
Take for example grüner veltliner, perhaps the most striking example of a grape that moved from the obscure, through the wine geeks and broke through in a big way on the main stage. While not all geek wines enjoy this kind of success, it's worth paying attention to the geek wines of the moment to see what might be in our collective futures. Obscure wines require a certain devotion and mind set if one is to truly learn about them, and I for one am happy to learn from those friends and peers so disposed. Who knows, I might even throw in a discovery or two of my own here!
