How to Ripen Cantaloupe

Cantaloupes should ripen on the vine for the best fresh flavor. However, if you’ve already harvested the fruit, you can let it continue ripening for a few more days to improve its color, texture, and juiciness.

Check when the fruit changes color. Never pick a cantaloupe when its skin is still green, as it will not ripen properly. When the skin begins to turn color or shows a yellow hue, it’s likely ripe.

• Do not rely solely on the color when harvesting cantaloupe. A green cantaloupe is definitely not ripe, but a yellow or colored one might not be either.
• However, even if the cantaloupe isn't fully ripe, you can still estimate its ripeness based on its color.
• Cantaloupes should be fully ripened on the vine. Unlike other fruits, the sugar content in cantaloupes won’t increase after being harvested, meaning they won’t get any sweeter once picked. While the color and texture may change, the sweetness will not.

Look for cracks around the stem. Typically, a ripe cantaloupe will show a small crack around the stem where it connects to the fruit.

• If you're unsure whether the crack is deep enough or fully developed, gently press near the stem of the fruit. Place your thumb right next to the stem. Only apply light pressure, and the stem should detach easily.

Harvest the fruit. Once the cantaloupe has turned yellow and the stem area shows a complete crack, it’s ready to be harvested.

• Don’t wait too long to pick the cantaloupe after it’s ripe. If it falls off the vine on its own, it may be overripe. At this point, the flavor and texture will not be as good.

Understand what happens. As mentioned earlier, the taste of the cantaloupe will not change if you attempt to ripen it after it has been harvested, as the flesh doesn’t contain starch to convert into sugar. However, you can still improve its color, texture, and juiciness, so this process can still be helpful if you’ve picked an underripe or overripe melon.

Place the cantaloupe in a brown paper bag. Choose a bag large enough to fit the melon with some extra space. Do not wrap the cantaloupe too tightly. Ideally, the bag should leave a small gap to allow airflow.

• Remember to close the bag tightly when you begin the ripening process.
• The ethylene gas produced by the cantaloupe during ripening will be trapped inside the sealed bag. This buildup of ethylene will accelerate the ripening process.
• Use a paper bag instead of a plastic one. Paper bags have ventilation holes, allowing carbon dioxide to escape and oxygen to enter. Without this airflow, the melon could ferment.

You can add a banana or an apple to the bag. Placing a ripe banana or apple in the bag will increase the amount of ethylene gas inside, which will speed up the ripening process of the cantaloupe.

• Bananas and apples release higher amounts of ethylene gas when ripe, making them ideal for ripening melons.

Keep the cantaloupe at room temperature until it ripens. The ripening process usually takes just a couple of days, sometimes even less.

• Ensure the melon is not placed in a spot that is too hot or cold. Avoid areas with high humidity or strong drafts.
• Occasionally check to make sure the melon doesn’t ripen too quickly.

Check the stem area. If you’re buying the cantaloupe rather than picking it from your garden, first make sure that there’s no stem on the fruit. Don’t buy a cantaloupe that still has a stem, as this means it was harvested before it fully ripened on the vine. Such a cantaloupe will never ripen properly.

• You should also inspect for any cracks around the stem area. If there are tears on the skin around the stem, it could mean the melon was harvested too early.
• Remember, the stem end of the cantaloupe should be slightly indented, as this indicates the melon was easily detached from the vine. If the stem end is raised, this is another sign it was picked prematurely.
• Avoid choosing melons with soft, visibly moist stem ends, as this suggests the fruit has overripe.

Examine the netting pattern on the skin. The cantaloupe's skin should feature a thick, textured “netting” that covers the entire surface.

• However, the netting may not be uniform throughout. Don’t expect the fruit to be perfectly even in its pattern.

Note the color. If you're purchasing a cantaloupe instead of picking it from your garden, check the color of the skin before buying. The skin should have a golden, yellow, or peachy hue.

• If the skin still has a hint of green, this means the cantaloupe is not yet ripe.

Check with your sense of touch. Gently press on the bottom of the cantaloupe. The skin should slightly indent when you press. If it feels firm, allow it to ripen at room temperature for a day.

• On the other hand, if the cantaloupe indents too much or feels mushy, it’s overripe.
• Similarly, lift the cantaloupe to check its weight. A ripe melon should feel heavier for its size.

Smell the cantaloupe. Smell the bottom of the melon, not the stem end. The raised part of the fruit should be near your nose when you inhale, and you should catch a sweet, fragrant scent if it’s ripe.

• If you don't detect any fragrance, let the melon ripen for another half day.
• If you’re unfamiliar with the smell of ripe cantaloupe, focus on the recognizable sweet aroma.
• The cantaloupe will begin to soften and release fragrance from the bottom first, so the smell at the base will be the strongest and easiest to identify.
