  1. Put the blueberries in a basket and wash them in cold water. Handle them gently because they get bruised easily.
  2. Drain the water and pat any water that’s left on the blueberries. Pat them until they are completely dry.
  3. Place them on a freezer-proof tray or cookie tray. Spread them out evenly so they don’t clump together.
  4. Put them into the freezer and flash freeze them. They should be frozen in about 20 minutes or so, depending on how cold your freezer is.
  5. Once frozen, move all the blueberries into an airtight container or freezer bag. Once filled in the bag, squeeze all the air from the bag and put it back into the freezer.

How Do You Make Blueberries Last Longer?

How long blueberries last will start when you buy them and where you bought them from. The best way to keep them fresh longer is to buy quality blueberries. If you’re buying them from the grocery store, choose the best-looking berries. Make sure they are not bruised or have mold on them. If they do, they will probably go bad within a couple of days, even if you try to put them in the fridge.

If possible, avoid grocery stores when buying blueberries. Blueberries sold there are usually mass manufactured meaning millions of blueberries are harvested and packaged daily. This means the quality of the blueberries might not be so good. The timeframe between when it was harvested, packaged, shipped to the grocery stores, and put on the shelves could be anywhere between a couple of days to even a week.

Instead of the grocery store, you could try the farmers market if you have one in your city. Usually, these places will have freshly picked blueberries the day before it’s brought to be sold. Blueberries and most of the other produce are sold by individuals, not a corporation.

This means these blueberries are picked and packed with care and of the highest quality. Blueberries sold at the farmer’s market may be a bit more expensive than at the stores, but you’ll be getting good quality blueberries and those will last long.

Besides the grocery stores and farmer’s market, another great place you can get quality blueberries is to pick them yourself. During blueberries season, most farms allow people to come onto their farms and pick fresh blueberries! Picking blueberries yourself is a guarantee that you’re getting the best quality blueberries. Therefore, the blueberries you get from here will last the longest.

How To Tell If Blueberries Are Bad?

Blueberries start to go bad when they’re exposed to air for too long. You can tell if your blueberries have gone bad by looking at them carefully and checking for signs of spoilage.

Here’s what to look for:

Discoloration. If your blueberries have turned brown or greyish purple, they may not be safe to eat anymore. This discoloration may also be caused by mold growth on the surface or inside of the berries. Mold is another sign that your blueberries are no longer good to eat.

Slimy texture. If the texture of your blueberries feels slimy when you touch them with your fingers, it’s possible that they’ve spoiled and should be thrown away immediately because sliminess is a sign of bacterial growth that could make you sick if you eat them.

Bad smell. If there’s a strong rotting smell coming from your blueberries, they’re probably past their prime and should be thrown out immediately because this is another sign of bacterial growth (and possibly mold) on top of other signs like discoloration or sliminess.
