Guaiacol in whisky

Prepare stock solutions of H 2 O 2 (25 mM) and guaiacol (75 mM) in phosphate buffer. 4. Mix bG/HRP (0.25 μM enzyme), 100 μM guaiacol, and buffer (to make up to a total volume of 2 mL) in a 4-mL cuvette. 5. Set the spectrophotometer to monitor absorbance at 470 nm for 120 s, with a steady stirring inside the cuvette and add 0.5 mM H 2 O 2. 6.

Guaiacol is responsible for smoky flavour in whisky. The scientists knew that guaiacol could be trapped in ethanol (alcohol) clusters and not released fully into whisky. When water is introduced to the mix, guaiacol rises to the surface of the glass giving the drinker a full blast of smoky taste and smell upfront. The investigations of Björn Karlsson and Ran Friedman, researchers in chemistry at Linnaeus University in southern Sweden, claim to have discovered a chemical reason for water enhancing the taste of whisky in the glass.. The key is the presence of guaiacol, a substance that develops during the production process of whisky, and a major contributor to both the smell and the taste of the spirit. 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.

Guaiacol gives whisky its distinctive overall flavour and aroma. When water is introduced to whisky, the guaiacol molecules move upwards towards the top of the glass – which means you will end up getting more taste and aroma when taking a sip. 2021-02-11 The authors of the article don't understand that "whisky" (from Scotland) is not the same as "whiskey" (from anywhere else.)The discussion that the water opens the whisky up and makes the guaiacol more aromatic does not apply to whiskey that does not have a lot of this chemical in it, that is to say 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.

Phenol (which is a specific compound that also belongs in the overall group of ‘phenol’ compounds) and cresols make up the majority of phenolics found in whisky, and are responsible for the medicinal aromas you can get in a bottle of Laphroaig, for example. Cresols, particularly m-cresol, are compounds responsible for the somewhat medicinal aroma in both Scotch whiskies and adhesive bandages.1Guaiacol imparts a slight smoky aroma and eugenol, more commonly found in cloves, is found in many whiskies and is partly responsible for their spicy aroma.1, 3 It is chemicals called phenols (isomeric cresols, guaiacol and xylenols) in the peat smoke which flavour the malted barley, and so too the whisky.

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.
