Inspect it first

Beyond the 12 months pantry time. Shelf-stable foods tend to lose quality rather than turn unsafe; discard it if you notice mold, pests, damp clumps or a bad smell.

Background

Getting to know grits

Grits sit in the pantry staples section of our food guide. The USDA FoodKeeper database files them under the name “Grits (boxed)”. Going by USDA FoodKeeper, they last 12 months in the pantry. They fall into the lower-risk group, so storing them well is mostly about keeping quality rather than about safety. Best storage spot: it does not need the fridge; a dark, dry, cool cupboard suits it best.

Dry pantry staples keep for a long time because microbes can't grow without water. What wears them down instead is a mix of heat, moisture, air, light and insects. The majority don't turn unsafe after the best-by date; they just gradually lose flavor, aroma and texture. The exceptions are whole-grain products and anything with natural oils, since those oils can turn rancid.

Before you take a bite

How to spot spoiled grits

Odor

A rancid, sour or musty smell.

Texture

Clumps caused by moisture, or contents that feel damp.

Pests

Tiny insects, holes or web-like strands inside the package.

Flavor

A stale, flat or bitter taste means the quality has faded, even when it is still safe to eat.

Inspect your grits and tick each warning sign you see

No boxes ticked? That's encouraging. Even so, confirm how long it has been stored, because the germs behind food poisoning can't be seen with the naked eye.

Even one of these means it has spoiled. Toss it, and never taste it to find out.

What's happening

What makes grits spoil

Dry foods lose quality through moisture and oxidation, not bacteria. The oils in nuts, seeds and whole grains oxidize over time and go rancid, giving off a bitter smell a bit like paint. Damp conditions let mold grow and cause powders to cake, and warm storage attracts pantry moths and beetles.

Don't do this

Mistakes people make storing grits

  • Storing it in a cabinet above the dishwasher, stove or kettle, where rising steam and warmth hurry its decline.
  • Leaving packages open rather than moving the contents into airtight containers.
  • Topping up a half-full container with a fresh bag, which means the bottom layer is never finished.
  • Scooping it out with a wet spoon.

  1. 1Step 1

    Dry goods don't need the freezer; it is mostly a way to stop pests and slow rancidity.

  2. 2Step 2

    Seal it in an airtight container or a freezer bag that closes tightly.

  3. 3Step 3

    Allow it to reach room temperature before you open it, so condensation doesn't form inside.

Room temperature · 2-hour rule

Grits left out overnight

Grits are shelf-stable, so an overnight stay on the counter does no harm. Store them somewhere cool and dry, out of direct sun.

How to store it

Keeping grits in good shape

  • Keep it sealed airtight in a cool, dark, dry spot.
  • Store it well away from the dishwasher and stove, since heat and humidity hasten spoilage.
  • Mark the date you opened it on the package.
Package dates

What the dates on grits packaging mean

Best-by vs. sell-by

Counting from the purchase date, FoodKeeper allows unopened grits 12 months on the pantry shelf. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.

Past the printed date

Grits kept in good conditions are generally still safe after their best-by date. Before use, inspect the odor, appearance and flavor.

Shopping

Choosing good grits at the store

  • Inspect packages for holes, webbing or clumps.
  • Buy nuts and whole-grain flours only in amounts you'll use within a few months.
  • Choose the package with the latest best-by date on the shelf.
Waste less

Grits: ways to finish them in time

  • Rotate your shelves: older packages go in front, new ones behind.
  • Freeze nuts and whole-grain flours to keep them from going rancid.
  • Hold a 'cook from the cupboard' week using only what's already on your shelves.

Grits myths: fact or fiction?

  1. 1.Putting grits in the freezer kills any bacteria on them.
    You got it!
    Not this time.

    False. The freezer puts bacteria on hold rather than killing them. They start up again as the food warms, so let it thaw in the fridge, then cook or reheat it all the way through.

  2. 2.Grits hold up well in the freezer.
    You got it!
    Not this time.

    Partly. FoodKeeper does not list a freezer time for grits.

  3. 3.Grits can be kept in the fridge door.
    You got it!
    Not this time.

    False. Each time the fridge is opened, the door heats up. It does not need the fridge; a dark, dry, cool cupboard suits it best.

  4. 4.Grits have to go in the fridge to stay safe.
    You got it!
    Not this time.

    False. Grits are shelf-stable and keep 12 months somewhere cool and dry. For some foods the fridge can stretch out quality, but safety does not depend on it.

  5. 5.How long do grits last? Only the printed date decides.
    You got it!
    Not this time.

    False. Storage time runs from the moment you open, cook or buy the food. A printed best-by date speaks to quality, and opening a package changes the countdown.

Reader questions

Grits: frequently asked questions

Can you freeze grits?
FoodKeeper does not list a freezer time for grits.
Do grits need to be refrigerated?
No, not for safety reasons. Grits last 12 months in a pantry that stays cool and dry.
How can you tell if grits have gone bad?
Odor: a rancid, sour or musty smell; Texture: clumps caused by moisture, or contents that feel damp; Pests: tiny insects, holes or web-like strands inside the package.
Do grits go bad after the printed date?
Grits kept in good conditions are generally still safe after their best-by date. Before use, inspect the odor, appearance and flavor.
What is the source for these storage times?
They come from USDA FoodKeeper, the food storage database run by the USDA Food Safety and Inspection Service (FSIS). We last checked this page against the current FoodKeeper release.
What temperature is best for storing grits?
Set the fridge to 4°C (40°F) or below and the freezer to -18°C (0°F). The dial on a lot of fridges is optimistic and the real temperature runs higher, so a cheap appliance thermometer is money well spent. A fridge running even a few degrees above 4°C will noticeably eat into the not needed fridge window for grits.
What should I store grits in?
Use an airtight container in a cupboard that stays cool, dark and dry. You want to block air and moisture, keep smells from traveling to other food, and be able to tell at a glance how old the food is. Jot the date on the lid or on a label so there is never any guesswork about its age.
Is the fridge door a good spot for grits?
It does not need the fridge; a dark, dry, cool cupboard suits it best.
Can you refreeze grits?
Yes, but only when they defrosted in the refrigerator and have not sat out at room temperature. Anything defrosted in the microwave or a cold-water bath needs to be cooked before it goes back into the freezer. Quality drops a little with every freeze-and-thaw round, so freeze in portions you'll use in one go.
Does freezing kill bacteria in grits?
No. At -18°C (0°F), bacteria stop multiplying, but they aren't killed off. Once grits thaw, any bacteria that were there wake up again, so defrost in the fridge and, where relevant, bring it up to a safe temperature when you cook or reheat it.
If grits smell okay but are beyond the storage time, are they still safe?
With a low-risk food such as grits, going beyond the storage time generally affects quality rather than safety. Look for mold, sniff for off odors and notice any strange taste, and get rid of them if anything seems wrong.
