How Best to Store Blueberries to Increase their Shelf Life

The shelf life of blueberries sorely depends on how you store them. It is also easier to tell how long they will last based on how fresh they were when you first bought or picked them.

Depending on how many you have in stock, there are several ways in which you can increase the shelf life of blueberries.

If you intend to use them as soon as possible, you can leave them whole on the counter for 2 days at most. Ensure they are stored in a well-aerated place.

For longer storage, use any of the following preservation methods:


Blueberries will keep well in the refrigerator but in certain suitable conditions. Avoid placing them inside the crisper drawer. Such enclosed spaces prevent optimum air circulation, which can lead to faster rotting.

Use airtight bags or containers. Thoroughly inspect the berries. Remove any which looks squashed or blemished.

Avoid washing before long-term storage, or if need be, ensure you blot the berries dry without leaving any moisture.

Mold will grow on the berries if they get exposed to moisture. Well, refrigerated blueberries will keep for up to 10 days.


Sometimes you may encounter an abundance of foods and wonder how to use them.

Freezing comes in handy when you want to use items in the future. Blueberries are easy to freeze.

Under the right freezing conditions, they can keep well for approximately 8 months. The key to effective freezing is to maintain a controlled temperature.

Fluctuating temperatures can cause changes in the composition of fruit and alter the taste.

Another crucial aspect of freezing blueberries is to pre-freeze. This involves spreading the berries on a tray and placing them in the freezer for roughly 2 hours.

This minimizes mushing when stored together. You can then transfer them into freezer bags and freeze them.


A more detailed storage technique is to preserve the blueberries through canning. This process helps to retain flavors and extend the shelf life of blueberries too.

Canning is not technical, and you can easily execute it at home.

You may have varied canning recipes, but the usual ingredients include sugar/sweetener, water, acid agents like lemon, fruits, and storage containers.

Ensure that the berries are well cleaned and sorted before canning. Any blemished berry that finds its way into the canning containers will affect the end results.

Fill your mason jars with the fruit and prepare the syrup by boiling the other ingredients. When hot, pour the syrup over the fruit, seal it, and place it in a hot water bath or canning tool if you have one.

This is a crucial step before cooling the canned fruits. Never alter the ratios of ingredients, as you may mess up the entire process.

Well, canned blueberries keep well for more than a year, approximately 1.5 years. Prolonged storage can alter its state and become undesirable.


One of the best ways of increasing the shelf life of food items is to dry them out. It is an ancient technique passed over generations.

Sucking out moisture from food items mitigates enzyme reactions and bacteria growth, which cause decay. You can use an oven, a dehydrator, or natural sunlight.

The duration for dehydrating will be different depending on which method you use. You can opt to blanch the berries first before drying.

Dried blueberries tend to have a concentrated taste. Well-dried blueberries can be stored at room temperature or frozen as well. They normally last for a whole year.


A great storage hack for extending the life of blueberries is to puree them and store them in a dry sugar pack. Ensure the berries are well-cleaned before placing them in storage containers.

Mix them with sugar and freeze well. It is best to store the berries in small batches.

Pureed berries are excellent in smoothies. You don’t have to thaw them, just remove them from the freezer and add them to the blender.

Blueberry Jam

A surefire way of enjoying fresh fruits is to make fruit preserves such as jam. Blueberries burst with zest and flavor, and what better way to enjoy them than in a jam?

Preparing jam is a great way to retain flavor. You also do not need many ingredients. For blueberry jam, you only need sugar, lemon zest, and berries.

For optimal flavor, soak the berries in sugar and leave them overnight before boiling. You can always adjust the taste by adding more sugar to your liking.

Pickled Blueberries

Whoever thought that blueberries could be pickled? Well, there is nothing new under the sun.

Pickled blueberries are quite common, with different variations in preparing them.

The simplest method is to mix all the ingredients in mason jars and leave them overnight. Ingredients commonly used include vinegar and sugar.

You can always make yours unique by adding spices, herbs, or even vegetables. Well, pickled blueberries can last a year.

How to Identify Spoilage

Pungent Odor

Off, the sour odor is always an indication of spoilage. Discard smelly blueberries as the scent can attract pests.

Squished Flesh

Fresh blueberries have a firm texture. Mushy flesh in blueberries may not mean that they are rotten. They could be overripe and thus should be used immediately.


Unusual discoloration on the flesh or skin could mean there is mold; thus, it is safer to discard such berries away.

Bruised Skin

Blemished skin paves the way for contaminants and bacterial growth. Such berries have a short shelf life.

Slimy Pulp

A clear sign of rotting is slimy, thick, and gel-like pulp. Discard such berries to prevent food poisoning.

Blueberries are versatile and especially popular in baking. The key to enjoying their benefits is to understand how long they last and look for the best storage techniques to prolong their shelf life.
