Reading about Mellow Mash in the Golden Age thread reminded me of when the brand was introduced. Although I don't remember exactly when that was, it was after I moved to Kentucky in 1978. Mellow Mash was a rarity at that time in that it was positioned as a premium line extension of Yellowstone. In fact, its original name was "Yellowstone Mellow Mash," with the Yellowstone part being deemphasized as time went on. Today, Yellowstone is bottom shelf but in those days it was considered a mainstream "popular price" brand alongside Early Times and Jim Beam.
