Expiration & Storage Tips
When does scotch expire?
Unlike many other foodstuffs, Scotch doesn't have a simple shelf life. That’s because the aging process stops as soon as the whisky is bottled. So if you have an unopened bottle of Scotch, it can technically last forever, if stored properly. Once the Scotch has been opened, however, it will start to oxidize and slowly degrade in quality. Depending on its conditions of storage, an opened bottle of Scotch can last between 1 and 2 years without significant loss of flavor. If you've popped the Scotch into the freezer, it can last indefinitely. But remember that freezing doesn't “lock in” the taste of the Scotch like it does for many other foods. Instead, freezing Scotch can dull the flavors.
How do you tell if scotch is bad?
One of the first signs that your Scotch has gone bad or is about to is a noticeable change in its smell: if it starts smelling sour or off, it might be time to consider getting a new bottle. Another sign of a spoiled Scotch is a change in its color. If your Scotch is getting darker after being opened, that's an indication that it's been oxidized. A change in flavor is another strong indicator: if your Scotch begins tasting bland or just 'not right', it's probably turned.
Tips for storing scotch to extend shelf life
• Store your Scotch upright: This will minimize the amount of Scotch in contact with the bottle cap
• Keep your Scotch out of direct sunlight: It can cause the Scotch to become paler and lose flavor
• Maintain a consistent temperature: Ideally, Scotch should be stored at room temperature (15 - 20°C)
• Avoid temperature extremes: Significant temperature fluctuations can cause the cork to expand and contract, potentially allowing air to enter the bottle and spoil the Scotch
• Keep your bottle sealed: Remember, once you've opened a bottle of Scotch, it is exposed to the air, which speeds up the oxidation process
