So from what I understand, when a particular bottle of something is "Joe's Discount Liquor Specially Selected", it simply means that the store was given samples from a few different batches of a 'small batch' release, and from those samples they could select which batch would be bottled for their store... correct?

Do these typically vary greatly from one 'selected' barrel to another, or not much at all? I get that with anything smaller batch or single barrel there WILL be variance, but I don't know if there's a difference between, say, "generic" (for lack of a better word) EC12 and a specially selected bottle.

Or maybe I'm WAY off and that's not what it means at all?
