How to Tell if Truffle Oil is Still Good
Preserving the earthy aroma and flavor of your 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.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long does truffle oil stay fresh?
Truffle oil stays fresh for about 12 months when stored properly in the refrigerator.
Does truffle oil go bad?
While not safety-critical like meat, truffle oil undergoes oxidation over time. If it develops an 'off' or oily-sour smell, it should be discarded to preserve the quality of your dish.
Can I freeze truffle oil?
You can freeze truffle oil, but the expansion of ice crystals may cause the oil to separate from its flavoring agents. Refrigerator storage is the preferred method for maintaining consistency.
Keep your truffle oil in a cool, dark spot—ideally the fridge—to keep that earthy magic alive for as long as possible!
