Johnny Drum Whiskey Johnny Drum Bourbons can be hard to come by because — even though it comes from Willett — it is a small-batch label and there are just not that many bottles around to be had. Johnny Drum Private Stock Kentucky Bourbon Whiskey is the top of the range, being the oldest and highest proof of the line. It’s now a non-age-statement dram, but previous versions were fifteen or so years old. And it’s bottled at 50.5% ABV, so there is plenty of power to go around — most of us will take it on the rocks or with a splash which really opens up the flavors and aromas. It took the Gold Medal at the San Francisco World Spirits Competition.
