LOUISVILLE, Ky. (WHAS11) — Distillers call it the “angel’s share” of the whiskey, when ethanol evaporates from the whiskey barrels during the aging process. But three parties are calling it quite the opposite, saying the ethanol is causing a whiskey fungus that covers their homes and cars. They’ve filed a class action lawsuit against Diageo, Brown-Forman, and Heaven Hill Distilleries.

For the past eight years, Joe Billy has put time, effort and lots of money into renovating his house, only to find he has an incessant mold problem. A problem he believes is caused by whiskey fungus.
