Video: What's Skunking Your Beer?

You don't need to be a beer aficionado to know when your beer has gone bad. But did you know that what is referred to as skunked beer is actually a breakdown of the hops' iso-alpha acids. The breakdown nearly mimics what is found in a skunk's behind.

This short Reactions video from the American Chemical Society explains why beer goes bad, how to prevent it and dispels the myth that heat is the culprit.

Cheers.
