Whiskey fungus (Baudoinia compniacensis), also called “Angel’s Share fungus” is the black that covers the rickhouses that store bourbon barrels as they age. The ethanol that evaporates creates the conditions that allows this fungus to grow. You could scrub it off but it would be covered in 3 wks.
As I wandered through the rolling hills of Kentucky, I stumbled upon a peculiar sight – the rickhouses that store bourbon barrels were covered in a mysterious black fungus. It was as if the very walls were being consumed by a dark, velvety blanket. I soon discovered that this enigmatic growth is known as Whiskey fungus, or Baudoinia compniacensis, and it’s a fascinating phenomenon that’s deeply connected to the aging process of bourbon. The fungus thrives in the conditions created by the evaporating ethanol, and it’s a testament to the intricate relationship between nature and the craftsmanship of whiskey production.
The Science Behind the Fungus
The Whiskey fungus is a type of fungus that’s specifically adapted to grow in environments where ethanol is present. As the bourbon barrels age, a small percentage of the liquid evaporates through the wood, creating a concentrated ethanol vapor that surrounds the rickhouse. This vapor provides the perfect conditions for the fungus to grow, and it’s not uncommon to see the black growth covering not just the rickhouses, but also nearby trees, buildings, and even cars. The fungus is incredibly resilient, and it can grow back in as little as three weeks if it’s scrubbed off. This unique relationship between the fungus and the evaporating ethanol has led to the fungus being dubbed the “Angel’s Share fungus,” a nod to the idea that the angels are taking their share of the whiskey as it ages.
The Impact on the Environment
While the Whiskey fungus may seem like a nuisance, it’s actually a relatively harmless growth that doesn’t pose a significant threat to the environment. In fact, the fungus is a natural part of the ecosystem, and it plays a role in breaking down organic matter and recycling nutrients. However, the fungus can be a bit of an eyesore, and it’s not uncommon for nearby residents to complain about the unsightly growth. Despite this, the fungus has become an unlikely tourist attraction, with many visitors flocking to see the mysterious black growth that’s synonymous with the bourbon industry.
A Symbol of Tradition and Craftsmanship
The Whiskey fungus is more than just a curious phenomenon – it’s a symbol of the tradition and craftsmanship that goes into producing high-quality bourbon. The fact that the fungus grows in response to the evaporating ethanol is a testament to the patience and dedication that’s required to age bourbon to perfection. As I stood in front of the rickhouse, watching the fungus grow in the misty air, I felt a deep appreciation for the art of whiskey production and the unique characteristics that make bourbon so special. The Whiskey fungus may be a small part of the bourbon-making process, but it’s a reminder that even the smallest details can have a profound impact on the final product.
As I left the rickhouse and continued on my journey, I couldn’t help but feel a sense of wonder at the mysterious world of Whiskey fungus. It’s a reminder that even in the most unexpected places, there’s often a fascinating story waiting to be uncovered. Whether you’re a bourbon aficionado or just a curious observer, the Whiskey fungus is a phenomenon that’s sure to captivate and inspire. So the next time you’re sipping on a fine bourbon, remember the tiny fungus that’s working behind the scenes to create the perfect aging conditions – it’s a small but vital part of the bourbon-making process, and a testament to the magic that happens when nature and craftsmanship come together.
