Inspect the Blueberries Before storing, sort through your blueberries and remove any that are soft, mushy, or moldy. This prevents spoilage from spreading to the rest.
Prepare a Vinegar Wash Mix a solution of 1 part white vinegar to 3 parts water. This wash kills bacteria and mold spores, which helps extend the freshness of your berries.
Gently Wash the Berries Place the blueberries in a colander and gently swish them in the vinegar solution. Be careful not to crush them during this step.
Rinse Thoroughly After the vinegar wash, rinse the blueberries under cold water to remove any vinegar taste. This ensures they're clean and ready for storage.
Dry Completely Spread the berries out on a clean towel or paper towels. Let them air dry completely, as moisture can lead to mold growth in storage.
Store in a Breathable Container Line a container with paper towels to absorb excess moisture. Place the dry blueberries inside, but avoid sealing the container tightly. Use a vented container or leave the lid slightly ajar.
Keep Them Cool Store the container in the refrigerator. The cool temperature slows down spoilage, while the breathable container prevents excess humidity buildup.
