How Long Leftover Halloween Candy Really Lasts: The Pieces to Eat First and the Ones That Keep

It's three weeks after Halloween, and the candy bowl on the counter is still half full. The candy corn has gone a little stiff, a few caramels are stuck to their wrappers, and the chocolate bars sitting near the toaster look dull. You're not sure what's still worth keeping and what's just taking up space.

This is not your fault. Fun-size candy rarely has a clear date on each wrapper, and a bowl of mixed treats ages at different speeds. But a food safety expert at Virginia Tech has laid out how long each kind lasts.

Why every candy ages on its own clock

According to Virginia Tech, food scientist Alexis Hamilton based her guidance on figures from the National Confectioners Association, the candy industry's trade group. The ranges are wide because the candies are so different: some are mostly sugar, some are soft and chewy, and some, like chocolate, are sensitive to warmth.

Storage matters as much as the type. Dark chocolate keeps longest when wrapped in foil and stored in a cool, dark and dry place, and opened or partially eaten candy should go into an airtight container.

Your candy eating order

• Eat now: Homemade treats are best eaten shortly after they're made. A partially eaten caramel or candy apple needs the fridge.
• Next, opened candy corn: About 3 to 6 months once the bag is open. Unopened, it lasts about 9 months.
• Then caramels: About 6 to 9 months when stored properly, sometimes up to 12.
• Then opened jellied candies: About 6 to 9 months. Unopened, soft sweets last about 12 months.
• Milk and white chocolate: No more than 8 to 10 months.
• Keep for later: Hard candy lasts up to a year at room temperature or in a cool, dry spot, and dark chocolate can keep for 1 to 2 years wrapped in foil in a cool, dark, dry place.

Plan B for the chocolate you won't get to: chop the dark chocolate and melt it into a pan of salted dark chocolate hazelnut bark, which sets in the fridge in about 30 minutes and makes an easy holiday gift.

When the stash should go

These ranges are about quality and come from the candy industry's own guidance, so treat them as a guide, not a guarantee. A bowl that sat next to a warm stove or in direct sun won't keep as long.

Hamilton's red flags are simple: off-odors or off-flavors, anything fuzzy growing on a piece, or a sealed package that looks bloated. Any of those means it goes in the trash. When in doubt, throw it out.

Mixed bowls also make allergens easy to miss. If anyone in your home has a peanut, tree nut, milk or other food allergy, keep candies in their original wrappers so the labels stay readable, and check them before handing a piece over.

Eat the soft stuff first, wrap the dark chocolate, and keep the hard candy for later. That's the trick.
