So I'm reading this article, and they allude to the "premium bourbon trend" starting in the 1980s. I guess they're referring to the introduction of Blanton's and the single barrel bourbon trend started by Elmer T. Lee?

I guess my question is this: Before the 80's, there clearly were a couple of premium bourbons, like VXOF, and VVOF, but those older expressions of Old Fitz might be the only ones I know of. I'm drawing a blank when I try to think of any single barrel or otherwise extra-aged or special bourbons which were introduced prior to the 80's?

Anyone know some backstory on the history of the high-end bourbon?
