How long does baking chocolate last?

FoodKeeper gives baking chocolate 1 to 2 years unopened, as a guide to quality. Once opened, that's 1 year in the pantry.

How to store it

Keep it wrapped, somewhere cool and away from strong smells. It takes on smells easily.

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

A white or grey film is called bloom. It's fat or sugar rising to the surface, and it's harmless, though the texture can suffer.

USDA says spoiled food develops an off odor, flavor or texture, and that if it has, you shouldn't eat it.

Worth knowing

FoodKeeper's figure is for solid unsweetened and semi-sweet chocolate, not milk chocolate. Check the pack for anything else.

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.
