Whiskey fungus, also known as Baudoinia compniacensis, has been causing concern among homeowners and property developers in the vicinity of bakeries and distilleries worldwide. In this article, we will explore what whiskey fungus is, its effects on the environment, and the recent developments regarding its control.
What is Whiskey Fungus?
Whiskey fungus is a black, sooty fungus that grows in areas surrounding bakeries and distilleries globally. It thrives on the ethanol vapours that evaporate from whiskey casks during maturation. The fungus appears as a black film on outdoor surfaces such as cars, homes, and trees, which can impact the value of properties. It is usually noticed when a powdery, black deposit is observed on outdoor surfaces such as garden furniture, windows, and cars.
Effects of Whiskey Fungus
Although research has not shown any adverse health effects on humans from exposure to the fungus, it can be damaging to trees and properties. The fungus can penetrate the bark of trees, blocking sunlight, and reducing the tree’s ability to photosynthesize. This can lead to the tree’s death over time. The fungus can also corrode metal and discolor masonry, leading to expensive cleaning and repair work.
Recent Developments
In 2021, a resident in Lincoln County in Tennessee sued Jack Daniel’s, the biggest-selling brand of American whiskey globally. The lawsuit followed the uncontrolled spread of the whiskey fungus in the area, which had resulted in the fungus covering buildings, cars, and trees. A local court in Lincoln County, Tennessee, issued an order halting the construction of a new barrel warehouse for Jack Daniel’s due to the impact of the fungus on the surrounding area. The order requires the company to take measures to control the fungus’s spread before the warehouse’s construction can proceed.
Controlling Whiskey Fungus
Controlling whiskey fungus can be challenging and costly. Due to the fungus’s airborne nature, it can easily spread to other areas, making it difficult to contain. Several approaches can be used to control the spread of whiskey fungus, including:
- Regular cleaning of outdoor surfaces: Regular cleaning of outdoor surfaces around distilleries and bakeries can help to reduce the spread of the fungus. This includes washing cars, windows, and outdoor furniture in the affected area.
- Use of anti-fungal coatings: The application of anti-fungal coatings on outdoor surfaces can help to inhibit the growth of whiskey fungus.
- Reduction of ethanol emissions: Since whiskey fungus thrives on ethanol vapours, reducing the amount of alcohol released into the atmosphere can help to control its spread.
