How Long Does Truffle oil Last?
Storage times and freshness tips for truffle oil in different conditions.
Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.

Signs of Spoilage
Rancid, metallic, or crayon-like smell; significant loss of truffle aroma; unusually bitter taste if sampled (not recommended for rancid oils).
How to Check
Check the 'best by' or 'expiration' date on the bottle. If past, open and perform a smell test. A fresh truffle oil should have a distinct, earthy, pleasant truffle aroma.
Storage Tips
Store in a cool, dark place away from direct sunlight, heat sources (like stoves or ovens), and extreme temperature fluctuations. Heat and light are the primary enemies of oil freshness, accelerating rancidity.

Signs of Spoilage
Pronounced rancid, metallic, or bitter odor; a faint or entirely absent truffle aroma; a dull, 'off' or stale taste; sometimes a slightly yellowish tinge if the oil was very clear initially (though visual changes are less common than smell/taste).
How to Check
Uncap the bottle and deeply inhale the aroma. It should smell distinctly of truffle, not sour, metallic, or like old crayons. If in doubt, pour a small amount onto a spoon and smell it more closely. A tiny taste can confirm, but if it smells rancid, do not taste.
Storage Tips
Always recap the bottle tightly after each use to minimize exposure to air. Keep in a cool, dark cupboard. While some oils can last longer, truffle oil's delicate flavor compounds can degrade more quickly, even if the base oil isn't fully rancid.

Signs of Spoilage
Similar to pantry storage: rancid, metallic, or bitter smell; significant loss of truffle aroma. The oil may become cloudy or solidify in the fridge, especially if it's an olive oil base; this is normal and will reverse at room temperature, it is not a sign of spoilage.
How to Check
If solidified, allow a small amount to come to room temperature to perform a smell test. Look for the distinct truffle aroma. Any off-odors (sour, metallic, chemical, waxy) indicate spoilage. If the truffle aroma is completely gone, the quality has significantly degraded.
Storage Tips
Refrigeration slows down the oxidation process, extending the shelf life of the oil and preserving its flavor for longer. However, the cold can temporarily mute the truffle aroma; allow it to warm to room temperature for optimal flavor release before serving. Ensure the cap is tightly sealed to prevent the oil from absorbing odors from other refrigerated foods.
