Are you the proud owner of a highly-trained nose?

Do you have a discerning palate?

Or perhaps you are a certified supertaster?

Such terms suggest a roll of the genetically modified dice when it comes to one’s abilities to distinguish and identify the complex aromas and flavours of wine, whisky, brandy, rum, gin, and so forth. A connoisseur. A Sommelier. Or even a talented enthusiast. Skills that reside in nature rather than nurture. But this rather underhandedly hides the truth.

While our flavour hardware, i.e. our genes, play a significant role in our sensory interpretation of the world, expertise has a lot more to do with software rather than hardware. The exciting upshot is that, much like downloading a computer update, if you can hack your brain, you can hack your sensory abilities.

Hence, today we share three neurological insights that have the potential to change how you taste wine and spirits. While they may be at the fringes of convention, they are nonetheless grounded in science.

It’s no surprise that some single malt whiskies are decidedly briny, maritime, and unquestionably salty. But lab analysis reveals something odd — there’s no measurable sodium in scotch whisky. So how can whisky taste salty?

This isn’t some kind of whisky witchcraft. It’s neuroscience, chemistry, and perception all conspiring together in a delicious illusion. So join me as we get to the bottom of this longstanding debate, to answer once and for all, how can scotch whisky taste salty?

The fragrance of farms, a suggestion of soot, or even a pipette of petrol. These are just a small selection of favourably foul flavours in whisky, wine, and other sensory stimulating swigs and snifters. Some have even been bounded into their own trending pigeonhole of mustiness – rancio. Our love of disgust is much wider though. How about that tonic in your gin, the barnyard in your burgundy, or the wood glue in your rum?

Long chain fatty acids (LCFAs) have sparked much conversation within the scotch whisky multiverse over the years. These tyrants of turbidity are the architects of making some whiskies go cloudy once water or ice are introduced. Hence, they are routinely removed in some whiskies through chill-filtration. But does chill-filtering whisky affect its taste?

A conclusive answer is yet to be published, however, recent studies on Baijiu (China’s traditional spirit), have shed new light on how LCFAs interact with key aroma compounds, and the results are both enlightening and surprising. These findings could have profound implications for Scotch whisky, particularly as interest in mouthfeel, texture, and flavour retention grows.

You pour yourself a dram of whisky, hold it up to the light, and immediately, words flow effortlessly. Amber, deep gold, russet, mahogany. The colour is easy to define. But then, you bring the glass to your nose, take a deep inhale, and suddenly... hesitation. What exactly is that aroma? Something sweet? Maybe fruity? Or is it more like an old leather armchair next to a roaring fire?

This is the great paradox of whisky appreciation—describing its colour is straightforward, but putting its flavour into words can feel like trying to explain a dream. The reason? Flavour is one of the most elusive, subjective, and neurologically complex experiences we have, and our language, perception, and even biology conspire to make it tricky to articulate.
