Thanks for mentioning that , Gary. I too was impressed by Mellow Mash, it has a richness that few bourbons today emulate. It dances over the tongue and there are many things going on at once. Wathens has it, It's pedigree and Mellow Mash are shared. Gts has it. I feel that Woodford Reserve, and I like WR for what it is, does not. It seems to me to be somewhat one dimensional, in a Maker's Mark, Ten High, way.
I felt Bobby's Yellowstone Mellow Mash from the early 1980's beat almost any bourbon out there today, premium, super-premium, whatever.
