Expiration & Storage Tips
When does cognac expire?
Since cognac is a spirit and very high in alcohol content, it does not technically expire, no matter whether it has been opened or not. However, once opened, the taste can begin to alter due to exposure to air. An unopened bottle of cognac can last indefinitely if stored correctly (cool and dry conditions, away from light). If the bottle has been opened, its quality can remain almost unchanged for 6 months to 1 year, but after 2 years or more, you could notice significant changes in flavor.
How do you tell if cognac is bad?
Cognac doesn't go bad in the same way food does. However, it can become less enjoyable to drink over time after being opened. Signs that the quality of your cognac has declined include a change in color (it might become cloudier), a change in scent (it may lose its rich, fruity, nutty or spicy scent), or a change in taste (it may lose its depth and complexity). These changes are more noticeable in top-quality cognacs, while cheaper versions might not show a noticeable decline in quality.
Tips for storing cognac to extend shelf life
• Keep your bottle of cognac in a cool, dark place, away from heat and light. An ideal temperature is between 15 to 20 degrees Celsius.
• Store the bottle upright, especially if it’s opened. This will reduce the amount of cognac in contact with air.
• Once opened, consider transferring the cognac to a smaller bottle if you're not going to finish it quickly. This will reduce the amount of air in the bottle, slowing down the oxidation process.
• If your cognac came in a wooden case, it is best to keep it in the case when not in use. The wooden case will protect it from light and temperature variations.
• Do not freeze your cognac. Unlike other spirits, cognac's complex aroma and flavor profile can be altered negatively by freezing.
