II. Ripening & Market Availability
As a late-maturing sweet orange variety, the Gannan Navel Orange’s harvest season is concentrated from early November to mid-December.
-
Early November: Early ripening stage. The peel still has a greenish-yellow tint, offering a sweet-tangy taste as the flavor begins to develop.
-
Late November to Mid-December: Peak flavor period. Sugar content is fully developed, acidity decreases, and the aroma is at its richest.
-
After January: Some late-maturing varieties or stored fruits may still be available, though the flavor of fresh fruit slightly declines.
The flavor continues to improve after harvest as the fruit undergoes natural sugar conversion, making it the quintessential fresh citrus fruit of the autumn and winter seasons.
