How to Tell if Truffle Oil is Still Good
How to Store and Identify Fresh Truffle Oil
Truffle oil stays fresh for about 12 months in the refrigerator when stored properly.
Truffle oil adds a luxurious, earthy depth to dishes, but its distinctive aroma is sensitive to environmental factors. Because it is often infused into a carrier oil, it can degrade over time due to oxidation or light exposure. Proper storage in the refrigerator helps preserve the volatile compounds that give truffle its signature profile. While the oil itself doesn't typically 'spoil' in a way that makes it dangerous like meat, it will lose its potency and flavor if left exposed for too long. Monitoring the scent and clarity of your oil is the most effective way to ensure you are getting the full aromatic experience intended by the chef.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
