Dilution of Whisky -- the Molecular Perspective (nature.com)
From a new published paper in Scientific Report by Bjorn C. G. Karlsson and Ran Friedman: Despite the growing knowledge of the nature of water-alcohol mixtures on a molecular level, much less is known on the interaction of water, alcohol and small solutes. In particular, the nature of the interaction between the solvent and taste-carrying molecules, such as guaiacol, is not known. To address this gap, we used MD simulations to study the distribution of guaiacol in water-alcohol mixtures of different concentrations. Our simulations revealed that guaiacol is present at the air-liquid interface at ethanol concentrations that correspond to the alcohol content of bottled or diluted whiskies. Because the drink is consumed at the interface first, our findings help to understand why adding water to whisky helps to enhance its taste. A molecular understanding of the nature of taste compounds in water-alcohol mixtures allows for optimizing the taste of alcoholic spirits. [...] Overall, there is a fine balance between diluting the whisky to taste and diluting the whisky to waste.
I am hoping, though, we can all come together and agree that:
The dilution of whiskey is morally wrong.

Boss: How did like that bottle of whiskey I gave you for Christmas?
Employee: It was just right.
Boss: Just right? Is that all?
Employee: Yep, if it had been any worse, I couldn't have drunk it and if it had been any better, you wouldn't have given it to me.
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 NOT SCOTCH.
Adding water to Irish Whiskey, or good ole American Bourbon Whiskey, is not going to have the same effect. Adding a couple teaspoons of cool water to your delicious smoky single malt from Islay will make a noticeable difference and open op the "nose" of the whisky.
True "whisky snobs" know the difference.
