How long does instant coffee last?

FoodKeeper gives instant coffee 1 year unopened, as a guide to quality. Once opened, that's 2 to 3 months in the pantry.

How to store it

Keep the lid tight and the spoon dry, because a damp spoon sets the granules. Keep it away from the kettle's steam.

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

Clumped or faded coffee has lost flavor. It's a quality issue, unless you see mold.

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 2 to 3 months once opened, so one small jar in use is better than several open at once.

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.
