On the one hand, if you find a product you like, who cares about the story behind it?
On the other hand, when some brands are charging an arm and a leg (like Pappy Van Winkle) as other, less expensive, brands made by the same people with the same equipment (like Buffalo Trace), then it might be worth it see what the difference is between the "high end" and "lower end" brands.
I did a blind taste test and found I liked the mid range whiskey the best.
