Tennessee state law defines Tennessee whiskey -- including being aged in new charred oak barrels.
The definition fits Jack Daniels to a "T."
Now, some lawmakers are considering revisions.
One would permit reuse of barrels, which would allow George Dickel to put Tennessee whiskey on its label, too.
Officials at Jack Daniel's oppose the change.
Legislator Bill Sanderson sponsored the measure.
He says there are a lot of ways to make high-quality whiskey, not just the Jack Daniels way.
