Whisky is usually diluted down to roughly 40 percent ethanol before being bottled, though. Computer simulations showed at this concentration ethanol, and with it the guaiacol, floated closer to the surface. Adding a drop of water to whisky can make it taste a lot better – and it's all down to the behaviour of a molecule called 'guaiacol', scientists say. When it's freshly distilled, whisky is Guaiacol-Purified CAS Number: 90-05-1. Guaiacol is an agent thought to have disinfectant properties and used as an expectorant.

When water was added to the whiskey, guaiacol, a compound partially responsible for the peaty smell and flavor of scotch whiskey, was more present at the surface of the whiskey, while it was driven away from the surface when water wasn't added.

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.

Kära single malt whisky är bättre att dricka i sin rena form, njuta av eftersmak och arom Det visade sig att guaiacol i 40-graders scotch fördelas jämnt över hela 

Chemists in Sweden provide a molecular explanation for why this works. 2017-08-18 · However, when the simulated whiskey was diluted to about 25 percent alcohol, the guaiacol floated to the top and brought its smoky scent and flavor with it.
