Does Whisky Go Bad? Here’s How Long You Can Keep the Bottle Open
Many people keep different types of whisky at home. Some bottles are chosen for special celebrations, others are used for mixing cocktails, and a few are set aside for random events. Having a variety is ideal, but it also means that more than one bottle may remain open at the same time. Knowing how to store opened whisky properly helps keep its flavour and quality for longer.
Whisky does not spoil in the way food does, but once a bottle is opened, it begins to slowly change because of contact with air. Over time, the flavour may not remain the same. The drink may lose some of its character, and in rare cases, if stored carelessly, it could taste weird. However, whisky that is stored correctly in a sealed bottle is safe to consume even after being opened for several months.
The key tips for storage are simple. Always close the cap tightly to limit air exposure. Store bottles upright rather than on their side so the liquid does not affect the cap. Keep bottles in a cool, dark place away from direct sunlight, as high temperatures and light can damage flavour. If there is only a small amount left in the bottle, consider transferring it to a smaller, airtight container to reduce air contact.
By following these basic steps, opened whisky can remain good for a long time.
How Long Can I Keep My Whisky Bottle Open?
Experts believe that your whisky will maintain its taste and aroma for up to two years as long as the bottle is half full and you seal the cap tightly. Even with the bottle tightly sealed, there will be a loss in flavour and aroma, something that’s completely out of your hands. If you leave the bottle unscrewed or uncorked and expose it to the environment, then it’s obviously going to be unsafe to even consume.

How to Store an Opened Bottle of Whisky
There are also important storage conditions that you need to consider:
Temperature
Whisky should be stored in a cool, stable environment, away from any direct source of sunlight. The ideal temperature prescribed by experts is somewhere between 15-20 C. Anything hotter than this can affect the integrity of the whisky’s taste and lead to flavour degradation.
Light
You may have noticed that whisky bottles are usually green or a darker shade to filter out any light exposure. Sunlight can lead to chemical reactions in the whisky that can alter the flavour and aroma.
Position
Store your whisky bottles in an upright position. You may have noticed wine being stored horizontally to keep the cork moist and prevent it from drying out. The same is not the case with whisky; it does not benefit from prolonged contact with the cork. Additionally, storing an opened bottle of whisky upright will prevent leakage.
Air Exposure
Once opened, whisky bottles should be stored with the cap tightly sealed to limit contact with air as much as possible.
Humidity
Whisky is relatively resilient to humidity as opposed to wine. However, too much exposure to humidity will lead to deterioration. It’s best to store your opened whisky bottle in a dry place to prevent moisture from seeping in.
Is My Whisky Safe to Drink?
Yes, it is if you follow the above mentioned conditions. Then you absolutely don’t have to worry about getting poisoned. Unlike wine, which may spoil due to exposure to oxygen and the overgrowth of certain bacteria and yeast, what prevents whisky from going down this path is its great alcohol content, typically ranging from 40% to 50%. This means that there’s basically no scope for bacteria or other microorganisms causing spoilage. Your bottle of whisky might just outlive you, but for that you’ll have to abstain from relishing it on a regular basis.
