Yesterday in a mom-and-pop I noticed a Mckenna Single Barrel in a different bottle. It was not the familiar, squatty cylinder, nor was the labeling at all distinctive. It was a simple, plain, unadorned, tall whiskey bottle. I didn't really examine it, as I didn't have much time at that point and the McKenna single barrel doesn't really interest me, but it didn't have an date on the bottle that I could find. Is this old? Brand new? Something else altogether?
