Searching for a quality whiskey can take time and effort. There are a lot of things that go into the taste and scent profile of a whiskey. Its flavour comes from the distillery, its water source, the grain recipe, how the barley is dried, how it’s distilled, and so on. However, given that the age of the whiskey is often featured on the bottle, it’s only natural to wonder how time changes it as well.

So, with that in mind, we’re asking the question: does whiskey get better with age? How does time affect the taste of whiskey, and does this continue in the bottle itself?

Whiskey and the Ageing Process

It takes about a week to distil whiskey in its original form, but the majority of time spent making whiskey is the ageing process, which happens in barrels. At a minimum, most whiskeys are aged for 3 years, but you can get bottles aged up to 25 years or even more before they’re bottled. Charred or toasted oak is used for the barrels and this helps to draw out butanol and methanol, making the taste smoother. The whiskey also gains flavour from the cask itself, and the casks are often treated with spices and other flavourings to enrich the whiskey further.

So, Older Is Better?

It’s not as simple saying that older whiskey is better, but there is definitely going to be a change in flavour depending on how long it has been barrelled. Whiskey that is aged for very long in a barrel (over 25 years) can start to lose the taste of the grain. However, in most cases, more years in the barrel means a more sophisticated taste with more notes to savour.

Blending And Age

The way that the whiskey is made will have a big impact on how it tastes. When it comes to a single malt whiskey, the taste tends to remain fairly similar whether it’s a 3-year, 8-year, 12-year or otherwise. It’s just that the longer it’s in the barrel, the smoother it gets and the more it gets the hints of the barrel’s flavour as well. For blends, different grains can tend to “dominate” the taste depending on how long it’s been left to age for. While single malts get more sophisticated but keep mostly the same kind of flavour profile, blends can change a lot.

Does Being In The Bottle Change The Taste?

A lot of people will say that having whiskey age “in the bottle” doesn’t change the taste. It’s true that it doesn’t work like wine, people don’t leave whiskey in the bottle to improve its taste.

However, factors such as oxidation and exposure to sunlight can change the taste of whiskey that has been sitting on the shelf. Most enthusiasts will agree that the change is not for the better, however. Hopefully, the information above has you feeling more informed about whiskey and how the ageing process can affect its taste. It’s not always a simple answer, but time, especially spent in the barrel, will have a big impact on the taste of whiskey
