How to Store Nuts So They Last
Store nuts airtight in a cool, dark place for short-term use, and refrigerate or freeze them for longer, their high oil content makes them go rancid at room temperature. Vacuum sealing further slows rancidity.
Nuts are mostly oil, which makes them delicious and short-lived, that oil turns rancid, developing a bitter, paint-like off flavour. Cool, airtight storage is the fix.
Cool and airtight
For short-term use, keep nuts airtight in a cool, dark cupboard. For anything longer, move them to the fridge or freezer, cold dramatically slows rancidity.
| Storage | Approx keeping |
|---|---|
| Cool pantry (airtight) | A few weeks to months |
| Refrigerated | Several months |
| Frozen | Up to a year+ |

Frequently asked questions
Should nuts be refrigerated?
For anything beyond a few weeks, yes. Their oils go rancid at room temperature, so the fridge or freezer keeps nuts fresh much longer.
How can I tell if nuts have gone rancid?
Rancid nuts smell of paint or old oil and taste bitter or sharp. Trust your nose, rancid nuts are unpleasant though not usually dangerous.
