What results from the presence of chlorophenols in beer?

Chlorophenols in beer are compounds that can result from the use of chlorine or chlorinated compounds in the brewing process, particularly during sanitation. When chlorophenols are present, they are known to impart undesirable flavors, which can often be described as plastic-like, medicinal, or Band-Aid-like. This off-flavor is detrimental to the overall sensory experience of the beer, masking its intended flavor profile.

Other flavor descriptors that may be associated with chlorophenols typically include harsh or phenolic tastes, which further emphasizes their negative impact on beer quality. Understanding the source and effect of chlorophenols is crucial for brewers aiming to produce clean and balanced beers, as even trace amounts can significantly affect the final product.
