The apples typically manifest a balance of sweet and tart flavors when they transition from the sugar accumulation phase due to robust photosynthesis during summer to the ripening stage in response to cooler temperatures.
Handling and Picking Techniques
The proper method of picking involves a gentle twist of the apple, ensuring the stem detaches from the tree while leaving the spur (the base from which it grows) intact. This technique minimizes damage to both the fruit and the tree, promoting better yields in subsequent seasons.
Step 1: Grasp the apple firmly but gently.
Step 2: Twist the fruit upward and turn slightly.
Step 3: Ensure the stem separates cleanly from the branch.
Post-Harvest Treatment
Once harvested, Jonagold apples benefit from immediate storage in a cool, dark place, which lengthens freshness and enhances flavor retention. Careful handling during picking must be complemented by careful storage to prevent bruising and degradation of the apples.
Ideal Storage Conditions: Maintain a cool environment with low humidity.
Recommendation: Keep the apples in a dark, well-ventilated area to prolong shelf life.
