Is unopened hazelnut oil safe to use after the expiration date on the bottle? Yes, provided it is properly stored and the bottle is undamaged - commercially bottled hazelnut oil will typically carry a “Best By," "Best if Used By," Best Before, or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the hazelnut oil will remain at peak quality.

How can you tell if hazelnut oil is bad or spoiled? The best way is to smell and look at the hazelnut oil: if the oil develops an off odor, flavor or appearance, it should be discarded.
