I asked about Prichard's TN Whiskey on a bourbon forum and received a reply
from Chuck Cowdery who stated:
"So what makes it "Tennessee Whiskey"? As far as the labeling rules go, it has
to be whiskey made in Tennessee. Whiskey is a controlled term and when a
place-of-origin is included it has to be true. That's probably why they went to
such lengths on the label to show that they 'made' the product in Tennessee,
even though it wasn't distilled there.
The whole charcoal mellowing 'Lincoln County process' is what distinguishes
Tennessee whiskey as most people understand it, but there's nothing about
charcoal mellowing in the Standards of Identity or TTB rules. Legally,
Tennessee whiskey is just whiskey made in Tennessee, and even 'made'
appears to be subject to interpretation."
Even so, I'd still like to try it!
