How to Taste Whisky Without Being Distracted by Age
By our Whisky Guru James Bunting (WSET Level 3 Spirits and Educator)
Age has long been seen as shorthand for quality in whisky. Something the industry has broadly been happy to encourage. But that had a little more weight to it when the main producing countries had similar climates - a year of maturation in a warehouse in Scotland isn’t too dissimilar to a year in Ireland.
But as whisky production has spread across the globe to new climates, with new wood types, cask sizes, and methods of production, a year no longer means the same thing from one bottle to the next. Even more so as distilleries themselves experiment with cask make-up - a Scottish single malt whisky will taste very different after 12 years in an ex-bourbon barrel compared to an ex-rum cask, even if the new make spirit is the same.
And that's really an important point worth sitting with. The longer a spirit spends in wood, the more of what you taste comes from the wood, and the less comes from everything that happened before it went into the cask. Extraction is cumulative. Vanillin, tannins, lactones, whatever a particular cask has to give — it keeps giving, year after year, while the lighter, more volatile aromatic compounds from fermentation and the cut are the first things to fade or fold into the bigger, oakier picture. Think of a tea bag left in the cup. Two minutes and you taste the tea. Twenty minutes and you're really just tasting stewed tannin, with the tea itself buried somewhere underneath. A cask does the same job, just over years rather than minutes (and with less tea, of course).
A brand ambassador I worked with used to say that if all flavour came from the casks then we would only need one distillery. Which is a cute way of pointing out that casks (and therefore time in them) is only one part of the picture.
If you’re lucky enough to have tried very old whisky, you’ll know it can start to taste like very old whisky, full stop. Sometimes even just, a bit, well, woody. Distillery character — the thing that's supposed to make one single malt recognisably different from its neighbour — gets planed down by decades of wood contact until two very old whiskies from entirely different distilleries can taste closer to each other than either does to its own ten-year-old expression. That's not a criticism of old whisky. It's just worth knowing that "old" and "concentrated distillery character" aren't the same thing. You’re effectively in the world where it’s almost all cask and no character.
But that is at least academically interesting when it’s a single cask. In most cases, an age statement on a bottle of whisky refers to the youngest spirit in the bottle. A useful fact but a misleading one. It says nothing of what else is in the blend. Or what type of cask was used (if it was a single cask). A 12 year old could be 95% older whisky with 5% at 12 years old. It will taste very different to a 12 year old that’s spent all its 12 years in a refill bourbon cask. But, despite these differences, ‘12’ is the number on the label.
That matters even more once climate is in the picture, as covered previously. A six-year-old whisky matured somewhere hot and humid can taste as developed as an eighteen-year-old from a cooler climate, because heat and humidity push maturation along faster — more aggressive expansion and contraction, more contact between spirit and wood, more of that tea bag being squeezed rather than just left to steep. Compare the two numbers directly and you're not really comparing quality, or even development. You're comparing weather and warehouses.
Another friend of mine says “you can’t rush a brew” - meaning you have to let tea steep, not just squeeze it lots and hope for the same result. Anyone who’s dabbled in slow cooking will understand this also. That’s not to say slower is better - just that slower will taste different to faster, even if the broad make-up is the same (think of our 6yo whisky and our 18yo Scotch).
It's part of why so many producers have moved towards No Age Statement expressions in recent years. Dropping the number isn't dropping standards — if anything, it frees a blender to combine casks of different ages and different characters to chase a specific flavour, rather than being boxed in by whichever cask happens to hit a round number. Some NAS whiskies are excellent. Some aren't. Exactly the same is true of age-stated whisky. So you can see that the number on the label isn’t so much a shortcut for quality but rather a bad steer down a dead end.
We can’t just throw that out though with no solution. So what should you actually pay attention to, if not the number on the front? Start with whether the spirit itself is still present. Pour something and ask whether you can still find traces of where it came from — the cereal, the fruit, the floral lift from a clean fermentation, the funk from a heavier cut — or whether all of that has gone quiet under a wall of vanilla, spice and tannin. Neither is wrong. But knowing which one you're drinking tells you far more than the number does. Balance is the other thing worth chasing: does the wood support the spirit, or has it taken over the room? A cask that's done its job well adds structure and depth without erasing what was underneath it.
To use my tea analogy again, can you taste the tea? Or is it all milk, sugar and crumbs from the biscuits you’ve been dunking in it?
If you want a useful and interesting exercise, skip the vertical tasting of one whisky at three different ages and try two whiskies of similar age from very different conditions instead — a cooler-climate malt and a tropical one, say, or a first-fill cask next to a tired old refill. You'll learn more about what's actually shaping flavour in twenty minutes than a shelf full of age statements will tell you in a lifetime.
None of this is an argument against old whisky, and it would be a bit rich to end this pretending otherwise. A well-aged spirit, matured patiently in a good cask, can deliver things nothing else can — deep dried fruit, leather, incense, a texture that only comes from decades of slow oxidation. That's a wonderful style of whisky, and plenty of drinkers, quite reasonably, prefer it - and it’s made more special by knowing how much more scarce an older spirit is. The point isn't that older is better or worse. It's that older isn’t a scoreboard and treating it as an objective measure of quality does a disservice to everything else that goes into making whisky taste the way it does.
So, next time you’re weighing up your next whisky purchase, don’t look for a specific age. Think instead about the cask, climate, and character of the whisky. That is a far more interesting way to go. Though, be warned, once you open that Pandora’s box, there’s no limit to how technical and geeky you can get. Believe me.
