When Are Blueberries In Season? And How To Make Blueberries Last Longer!

Going blueberry picking on a farm is a wonderful activity: a warm day in the sun, juicy blue fruit staining your fingers, and the promise of pies, smoothies, and muffins. How do you know when it’s the month to pick blueberries or buy them in a store? When are blueberries in season?

Blueberries are in season in the United States from June to August and South America from November to March. Do not rinse blueberries until you eat them to maintain their protective bloom. Always keep fresh blueberries in the fridge and use them within a week. Freeze blueberries for up to 10 months.

Blueberries are delicious, tiny blueberries that you can use in many dishes. Eat them raw or use them in baked goods.

Let’s look at when you pick and buy blueberries, how to store them and how to measure them in recipes.

When Are Blueberries In Season?

Blueberries grow on bushes native to North America and ripen in summer and fall.

Blueberries are usually in season from June through September in the US, Canada, Europe, and the UK. 

However, you can find blueberries in stores at other times of the year because they have slightly different seasons in different states:

  • Early blueberries ripen in April in warm areas like Florida, Georgia, and California.
  • In May, blueberries ripen in North Carolina.
  • June is the busiest month for blueberry farms, with harvests in California, Georgia, North Carolina, Oregon, and New Jersey.
  • In July, you’ll still find plenty of well-priced blueberries from Oregon, New Jersey, Washington, and Michigan.
  • August and September are the end of the US’s blueberry season, with the last berries coming from Oregon, Washington, and Michigan.

It is winter between November and April in the US, and you don’t get locally farmed blueberries. 

People still want blueberries on their oatmeal and in their pancakes, so stores import blueberries to keep up with the supply. 

Blueberry season in South America is from September to May, when it’s summer there. During these months, you will find blueberries imported from Chile, Peru, Argentina, and Mexico.

How Long Do Blueberries Last?

Blueberries are perishable, which means the fresh fruit spoils quickly if you don’t keep them in the fridge or freezer.

If you leave blueberries at room temperature, they will go bad within a day or two, especially if your home is hot and humid.

To ensure your blueberries last as long as possible, choose completely blue or purple berries with no hint of red.

Unlike bananas, blueberries won’t ripen once they’ve been picked.

Select firm berries in clean containers without any staining or leakage.

Avoid mushy, watery, or moldy berries as they are spoiled and no longer suitable to eat.

Fresh berries should have a shimmery, cloudy coating.

This silvery layer on the skin is called bloom. Bloom is natural and is the blueberry’s protection against pests and bacteria in the environment.

You want to keep blueberries bloom until you eat them, so don’t rinse or wash your berries until you use them.

How Long Do Blueberries Last In The Fridge?

Unless you plan on eating your blueberries immediately, you should store them in the fridge. 

Properly stored, freshly picked blueberries will last two weeks in the fridge. Store-bought fresh blueberries will last for 7 to 10 days in the refrigerator.

Follow these tips to keep your refrigerated blueberries as fresh as possible:

  • As soon as you get home, open the blueberries and check that there are no soft, moldy blueberries in the container. One moldy berry can spoil the rest.
  • Do not wash the blueberries. Water removes the bloom and speeds up the growth of bacteria. If you do wash the berries, dry them thoroughly before refrigerating.
  • Store the blueberries in the breathable container they come in or place the blueberries in a rigid container so they can’t get squashed by other fruit and vegetables. Put some paper towels in the bottom of the container to absorb moisture. Cover with clear, plastic wrap.
  • Do not store blueberries in the crisper drawer. Berries stay fresher with air circulating around them.
  • Use your blueberries as soon as possible.

How Long Do Blueberries Last In The Freezer?

If you pick or buy more blueberries than you can eat at once, it is best to freeze them. Blueberries freeze well and last between six months and a year in the freezer.

Follow these steps to freeze your blueberries:

  • Check through the blueberries for mold or squashed berries and discard them.
  • Do not rinse or wash the blueberries as the skins will become tough when frozen, and the fruit will stick together. The blueberries’ natural bloom is non-stick and prevents the berries from sticking together.
  • Lay out the blueberries in a single layer on a rimmed baking sheet. Place the sheet in the freezer.
  • Once the berries are frozen, store them in freezer-safe, airtight containers or zip-top freezer bags that you can stack easily. Freezing the right amount for a smoothie or muffins is handy as you can grab a bag when you need them.
  • Remember to label the bags to know when you froze them and how much each pack contains.

When you want some of your frozen berries, here’s how you thaw them – it only takes a couple of minutes:

  • Take a bag or container of blueberries out of the freezer.
  • Rinse the blueberries. (If you’re making a smoothie, throw in the unthawed, rinsed berries.)
  • Cover the berries with room-temperature water. Leave them to thaw for five minutes.
  • Drain the blueberries and dry them thoroughly on paper towels.
  • Use the berries in oatmeal, pancakes, or baked goods – you’ll find that they are still bright and juicy.

How To Measure Blueberries

If you don’t know how many berries you have in your container or pail, it can be tricky to picture how much they weigh.

Let’s look at how many blueberries make up standard measures. 

How Many Blueberries In A Pound?

Measuring blueberries by weight means measuring pounds. How many berries make up a pound of berries?

For accurate measuring, especially when baking, use a scale or cup measure rather than the number of berries as blueberries can differ in size. 

PoundsNumber of blueberries
½ 80-100
195-210
2390-420

How Many Blueberries In A Cup?

The average blueberry pie takes about three cups of blueberries. How many blueberries do you get in a cup?

CupsNumber of blueberries
65-70
2130-140
195-210
4260-270
5325-350

When measuring blueberries by cup, use a dry cup measure and fill it right to the top.

How Many Ounces In A Pint Of Blueberries?

We measure blueberries as a dry pint, not a liquid pint, like cream or milk. 

A dry pint measures volume (cubic inches), not weight, so pints of different ingredients will weigh different amounts in ounces.

For example, a pint of blueberries takes up the same volume of space as a pint of flour, but they wouldn’t weigh the same.

Look at the table below to see that a pint of blueberries has 12 ounces. A pint of flour only weighs 8 ounces.

Conclusion

Blueberries are tasty and healthy, so it’s helpful to have a supply of fresh or frozen berries.

Fresh berries will last up to 10 days in the fridge and nearly a year in the freezer so long as you store them correctly.

To use blueberries in recipes, rinse and dry them first, then measure carefully using a scale or cup measure.
