I don’t know. I believe it is the only “famous” Tennessee bourbon. I was at the Bourbon festival in Bardstown a few weeks ago. Lots to choose from but I don’t remember seeing Jack Daniels.
I drove by the Jim Beam main plant, Heaven Hills and Makers Mark plant yesterday and I believe they are all in Marion county, Kentucky. That is not a dry county.
You didn’t see Jack at the Bourbon festival, because it isn’t bourbon, it is sourmash whiskey.
Jack Daniel's probably wasn't invited, it being a Tennessee Whiskey rather than a bourbon. It's the charcoal-filtering that takes it down an "unorthodox" path, IIRC.
