Here are storage tips from Ward Upham of K-State:
• Store only the best quality apples.
• Pick as they are first maturing.
• Avoid skin breaks, disease or insect damage, and bruises on individual fruit.
• Store in a plastic bag to help retain moisture in the apples. The bags of apples may be stored in boxes to prevent bruising if they must be stacked or moved from time to time.
• Refrigerate at about 35 degrees. An extra refrigerator works well.
• Sort about every 30 to 40 days to remove fruit that may be beginning to rot.
