An expert’s guide to proper whisky storage

It’s already well documented how the making of a whisky is an art form in itself, honouring traditions centuries in the making and standing as a living reminder of a distillery's history, heritage and heart.

But it’s perhaps less known that storing whisky can be an art form in itself too. Done correctly and you can preserve the aroma, flavour and colour of a bottle for years - or even decades - to come. You can, poetically speaking, bottle time.

Done without care, improper whisky storage has the reverse effect. You can inadvertently dull a whisky’s flavour and devalue your own experience - whether that entails the dreams of building your own collection or just ensuring you get the best pour, every time.

Did you know there’s something very common that could be causing the cork to crumble into your whisky? Or that giving your bottles a shake might actually be beneficial? Daan van der Toorn does - and he’s here to share his decades of expertise.

Daan is the best person to speak to when it comes to appreciating a good whisky, appreciating good history, and really appreciating the merging point where the two meet.

His experience with whisky has seen him merge the past with the future. Working as a private client advisor, he’s not only helped influence the collectors and curators of tomorrow, ushering the start their journey with some distinguished bottlings from the past, he’s met seasoned experts and witnessed some of the most remarkable bottlings and collections.

Does whisky go off? Whisky storage FAQs

Before we dive into Daan’s expertise, let’s answer some of the more pressing questions that might need clarifying for novices and seasoned experts like.

Does whisky expire? Whisky doesn’t have a ‘best before’ or an expiration date like other food and drink. When stored properly - as Daan will explore in this article - it can, hypothetically, last indefinitely. So, no, whisky doesn’t ‘go off’ but certain actions can greatly disrupt or disturb an unopened bottle.
How long can an unopened whisky bottle keep? A bottle of whisky can be left unopened for years, even decades, without ever ‘going bad’ or losing its flavour - when cared for properly. Certain things like heat and light will impact how long you can keep a bottle unopened and still preserve it.
Does whisky age in the bottle? Unlike wine, whisky doesn’t continue to mature in the bottle. That is to say, bottling a whisky at 12-years-old means it’ll stay a 12-year-old whisky when you do eventually open it. However, if you don’t follow proper storage rules, the whisky’s flavour or aroma can be impacted in the bottle.
How to store an opened bottle of whisky? While Daan covers storage for unopened bottles and collections, you can preserve an opened bottle’s taste and aroma for longer with some tips, like limiting air exposure when not in use (such as decanting it into another smaller bottle that you can cork shut again).

Why is proper whisky storage so important - does it really make a difference?

It is important for a number of reasons. The first is the most obvious, it can really affect the quality of the whisky and affect the taste. If, for example, the whisky is kept in a bright room in direct sunlight it can evaporate. (And we’re sure some have used this as an excuse when they’ve helped themselves to an extra sip or two…)

Another risk when storing improperly is that the cork gets damaged and crumbles when trying to open it. This taints the whisky, ruining both the experience and its value.

And last - but certainly not least - if not stored properly the packaging could get damaged by sunlight or moisture.

What are some of the common mistakes people make with their whisky collections?

Most people know to keep their whisky out of direct sunlight for long periods of time but what I often see is that people store their whisky laying down. Because of the high ABV this could damage the cork over time and make it crumble when trying to open it.

It could also let air in which taints the flavour. I always recommend keeping whisky upright and, if you’re holding on to a collection for a longer time, give it a shake once a year so you wet the cork.

Moisture can also be a killer when it comes to packaging - labels can come off and some packaging, especially the whisky kept in the tubes with the metal lids, can start to rust. Keeping it in a cupboard or pantry out of sunlight, at a relatively consistent temperature and away from moisture is the best way to go.

If you are keeping your whisky in a shed or garage, make sure it is kept in boxes that keep the whisky free from all of those. My top tip is investing in insulated food transport boxes - they might not have been designed with whisky in mind, but they are great for this.

When stored correctly, how long can a whisky last?

Most bottles, if stored correctly and not opened, should stay absolutely fine until you open them. This can be years - or even decades. The trickiest part is the storage of them.

Once opened I would recommend drinking a bottle of whisky within 6 months to a year in general.

The other consideration is for people who pick up bottles from auction - especially whiskies from 1960, 1970, and 1980. With whisky that has been in the bottle for a long time it is hard to trace what the storage conditions have been. Which means that when you open them it might change character quite fast because of the (extra) oxidisation.

I have had this recently with a bottle of Red Label from the 1960s. When I first opened it, it was very vibrant and fruity but after a month it became a bit more dull and the fresh fruits became a bit more dusty. This is not necessarily a bad thing but something to be aware of.

What are some of your non-negotiables when it comes to whisky storage? What should the minimum effort be?

The minimum for me would be to store it in a cupboard or pantry where the temperature is the most consistent and also out of sunlight. Once a year, if storing for a long time as mentioned earlier, give it a shake or tilt to bring moisture to the cork.

If you have a collection that you are drinking I would still keep it in a cupboard away from direct sunlight but the tilting etc is not really necessary.

For people holding collections of high value, what are the ‘next steps’ when it comes to storage?

The first is insurance! If you get to the point with your collection that it becomes very valuable, get it valued and insured if you are keeping it at home. Many people forget about this but it is really important if you aren’t 100% sure about the storage conditions.

The next step for elevated storage would be a controlled environment, similar to how controlled environments work for storing wine. One great example on how to store whisky and other spirits is actually the liquid library in the archives in Menstrie.

A second option would be to get it managed or properly stored by a dedicated company. Many aficionados turn to reliable outsourcing when a whisky collection is too large to be kept at home.

Often you will pay a percentage on the bottle value for storage but they also cover all the insurance.
