IPAs can definitely get skunked. Skunking, also known as light struck, is a chemical reaction that occurs when beer is exposed to ultraviolet (UV) light. This reaction is caused by the breakdown of hop compounds called isohumulones, which release a compound called 3-methyl-2-butene-1-thiol (MBT). MBT is the same compound found in the scent glands of skunks, hence the term “skunked beer.”
IPAs, or India Pale Ales, are known for their strong hop flavors and aromas. They typically have a higher hop content compared to other beer styles, which makes them more susceptible to skunking. Hops contain light-sensitive compounds that are responsible for the unique flavors and aromas in beer. When these compounds are exposed to UV light, they can undergo a chemical reaction that results in skunking.
It’s important to note that not all IPAs will automatically get skunked. Skunking occurs when beer is exposed to direct sunlight or UV light for an extended period of time. If you store your IPAs in dark or opaque bottles, or keep them away from light sources, the chances of skunking are significantly reduced. Additionally, drinking IPAs on draft or from cans can also help minimize the risk of skunking, as these containers provide better protection from light compared to clear or green glass bottles.
Personal experience: I remember one time when I left a six-pack of IPAs on the back porch during a sunny summer afternoon. When I went to retrieve the beers later that day, I noticed a distinct skunky aroma and flavor. The hop-forward characteristics that I love in IPAs were completely overshadowed by the skunked taste. It was a disappointing experience and made me realize the importance of proper beer storage to avoid skunking.
While all beers have the potential to get skunked, IPAs are more susceptible due to their higher hop content. To prevent skunking, it’s best to store IPAs in dark or opaque bottles, keep them away from direct sunlight or UV light, and consider drinking them on draft or from cans. This will help preserve the fresh hop flavors and aromas that make IPAs so enjoyable.
