How to Store your Whisky Collection

You’re building your ultimate whisky collection, so you want to look after it, right? This is The Whisky Club's guide to storing whisky to keep it in optimal condition.

Avoid direct sunlight - Direct sunlight is not a friend to whisky. Do your collection a favour and keep those bottles somewhere safe and out of the sun.
Keep them cool - Although your collection would look great lined up on a mantlepiece above the fire, it’s not a good idea. Whiskies like cooler temperatures — room temperature or below is best. If you’ve got a cellar or a basement, that’d be ideal. Just make sure the bottles don’t get humid.
Keep your bottles upright - Store your collection upright, don’t lay the bottles down on the side. That’s because the high alcohol content of whisky can eat away at the cork. This could allow more air in during storage and potentially ruin the seal.
Limit exposure to oxygen as much as possible - Why? The goal here is to maintain flavour by keeping the whisky from oxidising. This can be achieved by decanting an open bottle into a smaller bottle(s).
Consider the shelf-life of open bottles - Once a bottle of whisky has been opened the alcohol will start to very slowly evaporate. The shelf-life of an open bottle of whisky is open to debate, but the general view is that it’ll last anywhere between six months and two years. The amount of change in flavour is variable, too. Sometimes the flavour will improve, sometimes not.
Fishing out the cork - If a piece of cork breaks off and gets into your whisky bottle, don’t worry, you haven’t ruined your whisky. You can easily filter it out using a sieve or coffee filter paper. If you leave it in there, over time it could erode in the whisky and that might affect the flavour.

There you have it, some pretty simple tips to keep those bottles in mint condition so you can keep growing and enjoying your collection!

Whisky Storage FAQs

Why should whisky be kept out of direct sunlight?

Direct sunlight can degrade whisky and negatively affect its flavour, so bottles should always be stored in a shaded or dark environment.

What temperature is best for storing whisky?

Whisky should be stored at cool, stable temperatures — ideally room temperature or below. Fireplaces, warm shelves or heated cabinets should be avoided. Cellars or basements make excellent storage spaces if they’re not humid.

Should whisky bottles be stored upright or on their side?

Whisky must be stored upright. Its high alcohol content can erode the cork if left in contact with it, compromising the seal and allowing in excess air.

How can I limit whisky’s exposure to oxygen?

To slow oxidation and preserve flavour, decant open bottles into smaller bottles when the fill level drops significantly. This reduces the amount of air inside the bottle.

How long does an open bottle of whisky last?

Once opened, whisky gradually evaporates. Most believe an opened bottle lasts between six months and two years, though flavour changes vary — sometimes improving, sometimes not.

What should I do if cork pieces fall into my whisky?

You haven’t ruined the whisky. Simply filter the cork out using a sieve or coffee filter. Leaving the cork in the bottle may cause it to erode and affect flavour over time.
