How long does quinoa last?

FoodKeeper gives quinoa 2 to 3 years unopened, as a 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 are best, and to avoid anywhere above or beside the stove, under the sink, or in a damp garage or basement. 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 odor, flavor or texture, and that if it has, you shouldn't eat it.

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.

Where FoodKeeper gives no figure, we say so instead of guessing. The date printed on a package is the manufacturer's, and it's about quality except on infant formula.
