While technically a single-barrel whiskey, this JD is more akin to a limited-edition, premium bottling in that there is minimal variation between the casks--they are all chosen for their adhesion to the single-barrel style.

The bottles are signed and the barrel number. The so obtained Jack Daniel"s Single Barrel has an alcohol content of 45%
