Storage Tips
- Do not wash blueberries until just before eating — the natural waxy bloom coating is a protective barrier against moisture and mold.
- Spread in a single layer on a paper towel in the fridge to prevent moisture buildup at the bottom of the container.
- Pick out any soft, mushy, or mold-spotted berries immediately — one bad berry releases spores that spread to neighbors within a day.
Ethylene gas — store carefully
Blueberries is sensitive to ethylene gas. Keep away from high-producers like avocados, bananas, apples, and tomatoes to slow premature aging.
How to Tell If Blueberries Has Gone Bad
Signs to look for
- Visible white or gray fuzzy mold starting on damaged or split skin.
- Juice leaking from the bottom of the container indicating crushed or rotting berries below.
- Shriveled, wrinkled skin with a fermented or musty smell rather than a fresh, slightly sweet scent.
Frequently Asked Questions
Why do blueberries have a dusty white coating?
That coating is called "bloom" — a natural waxy substance the berry produces to protect itself from moisture loss and external bacteria. It is safe and actually a sign of freshness; wash it off only right before eating.
Do blueberries need to be refrigerated?
Yes, for best life. At room temperature they last only 1–2 days. Refrigerated and dry, they stay firm and flavorful for up to 2 weeks. Always refrigerate if you plan to keep them more than a day.
Can you freeze blueberries straight from the store?
Yes — spread dry blueberries on a tray, freeze solid for 2–3 hours, then bag them. Do not wash before freezing; wash when you are ready to use them. Frozen blueberries keep their shape well due to their tough skin.
