If you need your hazelnuts to last for months, cold storage is best. This is true for both shelled hazelnuts and kernels. Shelled hazelnuts do not require any type of packaging when refrigerated or frozen, the shell protects them quite well. But if you need to store shelled hazelnuts, they need protection.
A hazelnut can last more than a year in the fridge if you keep its shell intact. If you are going to store hazelnut meats, it will only last about a year. In both cases, store the nuts in an airtight container with as little exposure to air as possible. In short, at room temperature, shelled hazelnuts should last at least 6 to 9 months, while shelled hazelnuts should last 3 to 4 months.
How do you know if shelled hazelnuts are bad? Stale hazelnuts often develop a bitter and unpleasant taste; if hazelnuts develop a bad smell or taste, or if mold appears, they should be discarded.
