4-Vinylphenol is a phenolic compound found in wine and beer. It is produced by the spoilage yeast Brettanomyces. When it reaches concentrations greater than the sensory threshold it can give the wine aromas described as barnyard medicinal band-aids and mousy. In wine 4-vinylphenol can react with other molecules such as anthocyanidins to produce new chemical compounds.
