Why the trees at the Jack Daniel distillery look like they've been blowtorched

On a recent walking tour of the scenic facility, I couldn't help but notice the trees looked like they had their bark blowtorched.

The bark was extremely black and gave the trees a dramatic appearance. That's because they have been tainted by Baudoinia compniacensis - a whiskey fungus that's found near distilleries.

This fungus attaches to warehouses and walkways at the 150-year-old distillery. Larry Combs, Jack Daniel distillery general manager, said the fungus has been cleaned off a few of the buildings at the distillery for cosmetic purposes.

"The funny thing about distilleries, especially old ones like Jack Daniel, they are where they are because of the water supply. You'll find these microorganisms near the water, and so the mold just comes with the setting," Combs told Business Insider.

This particular type of black fungus is common near distilleries because it uses ethanol as a source of energy for growth.

During the whiskey maturation process, at least 2% of whiskey escapes from a barrel as ethanol vapor - perfect for Baudoinia to thrive.

The mold doesn't seem to bother the locals, Combs said.

"We really don't get any complaints about the mold. Every once in a while we will get someone to call in, but more often than not people are just curious," Combs said.
