When encountering a skunky beer, it’s a common belief that heat is the culprit. However, this is a widespread myth. The truth is that skunking occurs due to light exposure, specifically UV light, which reacts with the hop compounds in beer. This reaction produces a compound that emits an odour reminiscent of a skunk, hence the term “skunky beer.”
What Causes Beer to Be Skunky?
Skunking happens when light-sensitive compounds in hops, called isohumulones, are exposed to ultraviolet (UV) light. This exposure triggers a chemical reaction that produces 3-methyl-2-butene-1-thiol (MBT), the compound responsible for the skunky aroma.
Here’s a breakdown of the skunking process:
- UV Light Exposure: When beer is exposed to UV light, especially from sunlight or fluorescent bulbs, it accelerates the skunking reaction.
- Hop Compounds React: The isohumulones in hops react with the UV light, leading to the formation of MBT.
- Skunky Odor: MBT is chemically similar to the compounds produced by skunks, resulting in the familiar skunky beer smell.
Why Are Cans Better?
One effective way to prevent skunky beer is by choosing the proper packaging. Cans are superior to bottles in protecting beer from light exposure. Here’s why:
- Opaque Protection: Beer cans are entirely opaque, offering complete protection against UV light, preventing the chemical reaction that causes skunky beer.
- Durability: Cans are more durable and less likely to break, making them a practical choice for transport and storage.
- Sustainability: Cans are also more environmentally friendly as they are easier to recycle and lighter to transport.
At Paniza Brewing, we appreciate the classic feel of a beer bottle. However, we predominantly use printed cans to ensure the best quality for our customers. This choice minimizes the risk of skunky beer and ensures that our brews maintain their intended flavour profile from the brewery to your glass.
Enjoying Beer Without the Skunk
To further ensure your beer remains fresh and free from skunkiness, follow these tips:
- Store in the Dark: Always store your beer in a dark place, away from direct sunlight or bright artificial light.
- Refrigeration: While heat doesn’t cause skunking, it can still affect the beer’s quality. Keep your beer refrigerated to maintain its optimal taste.
- No beer in the sun: You might stay under the sunlight, but if your beer does, that skunky feeling will follow.
Conclusion
The myth that heat causes skunky beer is debunked. Exposure to light leads to a skunky aroma. You can avoid this unpleasant experience by choosing cans and storing your beer in the dark. At Paniza Brewing, we take pride in protecting our beers from light exposure so you can enjoy them as intended.
