“Phenolic-4-VG, like cloves or carnations”
Certified beer flavour standard used to train professional beer tasters to recognize and scale the intensity of phenolic character.
4-Vinyl guaiacol is a key flavour impact character in German-style wheat beers. It imparts a distinctive clove-like note, being produced by specially selected strains of brewing yeast. In the case of other beers it is generally an off-flavour originating from wild yeasts.
