How long does quinoa last?
FoodKeeper gives quinoa 2 to 3 years unopened, as a US guide to quality. Once opened, it has no figure in FoodKeeper.
How to store it
Keep it sealed, in a cool, dry place. Rinse it before cooking, as the label usually says.
Keep it cool and dry. USDA says temperatures below 85°F (about 29°C) are best, and to avoid anywhere above or beside the cooker, under the sink, or in a damp garage or cellar. Reseal opened packs, or decant them into something airtight.
What to look for
Look for a musty or bitter smell, insects, or damp clumps.
USDA says spoiled food develops an off smell, taste or texture. The FSA says you can smell food with a best before date to see if it has spoiled, but that the sniff test isn't safe for food with a use-by date.
Worth knowing
FoodKeeper gives quinoa the longest unopened time of the grains here, at 2 to 3 years, but no figure after opening. Reseal it well and use it within your usual rotation.

How it works
FoodKeeper is USDA's food storage database. Its figures are guides to quality for food stored at cool room temperature, not safety cut-offs, and we show them as USDA gives them. FoodKeeper counts this from the date of purchase. Opened times start when you open the pack.
There's no UK shelf-life dataset, so these figures are from the US. The date on your pack comes first. On a UK pack, use by is about safety and best before is about quality, so never rely on this page to go past a use-by date.
Common questions
How long does quinoa last unopened?
2 to 3 years, according to USDA FoodKeeper, as a guide to best quality. FoodKeeper counts this from the date of purchase.
How long does quinoa keep once opened?
FoodKeeper gives no figure for an opened pack in the cupboard. FoodKeeper gives no fridge figure.
Can I eat quinoa after the best before date?
Best before is about quality, so quinoa past that date is usually safe, but may not be as good. A use-by date is different: never eat food after it.
