How to choose blueberries
Blueberries should be firm, plump, and uniformly deep blue with a naturally shimmery surface. They should show no signs of mold or softness. Gently shake the container; freely moving berries indicate they are firm and not moldy.
Reject blueberries that are shriveled or dull in color, signs they are old and less flavorful. Avoid containers with juice stains or excess moisture, which can promote mold growth.
How to store blueberries
For optimal freshness, blueberries should be stored in the refrigerator in a shallow container. Leaving them unwashed until you're ready to eat them helps prevent moisture from causing mold. Blueberries can last up to a week when stored correctly.
Excess moisture is the main enemy of fresh blueberries, so avoid washing them before storage. Airtight containers are not recommended as they need some air circulation. Keeping blueberries away from strong-smelling foods prevents them from absorbing unwanted odors.
✅ Extra Tip
How long do they last?
Blueberries can last for 1-2 weeks in the refrigerator. For longer storage, they can be frozen and kept for up to 10-12 months. Spread them out on a baking sheet to freeze individually before transferring to a sealed container or bag for the best results.
