Guaiacol is an agent thought to have disinfectant properties and used as an expectorant. Guaiacol is produced when the lignin found in wood is burned, and it’s partly responsible for the flavour of smoke-preserved food such as bacon and fish, as well as peated whisky and roast coffee. whisky. The main sources of phenolic compounds are the peating (smoking) process, the kilning (thermal degradation) process, as well as maturation (ageing) in oak barrels. The critical compounds are: Phenol, cresols (o-/p-/m-cresol), xylenols, ethylphenols and guaiacol [1]. The analysis of whisky … A few days ago, scotchwhisky.com (one of my favourite sources of whisky news and information) published a piece by David Tjeder entitled ‘Whisky Myths Guaiacol | C7H8O2 | CID 460 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards 2017-08-17 · Guaiacol is a small and mostly hydrophobic molecule that is able to interact with polar solvents via hydrogen-bonding and polar-aromatic interactions. Higher concentrations of guaiacol have been Guaiacol A phenol derivative created by the charring of wood, Guaiacol is also responsible for the sweet smoke flavour found in whisky, its distinctive flavour is balanced against phenol and cresol by regulating the temperature and duration of the peating.

Whisky is distilled to around 70% alcohol by volume (vol-%) then diluted to about 40 vol-%, and often drunk after further slight dilution to enhance its taste. The taste of whisky is primarily associated with amphipathic molecules, such as guaiacol, but why and how dilution enhances the taste is not well understood. Guaiacol, responsible for burnt / smoky notes – but discernible in taste only; Syringol, responsible for burnt / smoky notes – but discernible in aroma only; Cresol, which delivers the medicinal, earthy peat, organic and tar notes. Hence, a whisky that’s very heavily peated might have a very high proportion of syringol phenols in the malt. Guaiacol is an aromatic oil that ends up in whisky via wood creosote, which is a byproduct of the charred wooden barrels whiskies are typically left to age in. Guaiacol is also the most prominent cause of that recognizable smoky flavour unique to whisky. ‘This suggests that, in a glass of whisky, guaiacol will therefore be found near the surface of the liquid, where it contributes to both the smell and taste of the spirit,’ said Friedman.

Simple phenols such as phenol, the isomeric cresols, xylenols, ethyl phenols, and guaiacols arise through the thermal degradation of benzoic acid derivatives from malt and from peat smoke. Phenolic aldehydes such as vanillin, syringaldehyde, coniferaldehyde, and sinapaldehyde are formed from the breakdown of wood lignin during cask charring and maturation.
