Expiration & Storage Tips
When does truffle oil expire?
Unopened truffle oil generally lasts for up to 2 years when stored properly in a cool, dark place. However, the flavor can start to diminish after about a year. Always check the best by date on the bottle. Once opened, truffle oil should be used within 3 to 4 months for best flavor and quality, but can technically be safe to consume for up to 6 months. Truffle oil should not be frozen as it can affect the quality of the oil and breakdown the flavor.
How do you tell if truffle oil is bad?
The best way to determine if your truffle oil has gone bad is by smelling it. If it has an off smell or has lost its distinctive truffle aroma, it's time to toss it. Additionally, if the oil has become cloudy or the texture seems off, these are also signs that it might not be good anymore. Truffle oil does not typically have any visible mold or discoloration, so your senses of smell and taste are your best tools.
Tips for storing truffle oil to extend shelf life
• Store truffle oil in a cool, dark place, away from heat and light which can degrade the oil's flavor over time.
• Always screw the cap tightly after every use to prevent exposure to air, which can cause the oil to oxidize and lose its flavor.
• If you won't use it often, consider buying smaller bottles to ensure it doesn't go bad before you can use it all.
• Keep the bottle as upright as possible. Having the oil concentrated at the bottom of the bottle rather than spread out could help extend its shelf life.
