The sweet and tart taste of cherries is a favorite among many fruit lovers. Whether enjoyed fresh, in pies, or as a topping for yogurt or ice cream, cherries are a versatile and delicious addition to any meal or snack. But have you ever wondered what happens to cherries after they’re picked from the tree? Do they continue to ripen, or is their ripening process halted the moment they’re plucked? In this article, we’ll delve into the world of cherry ripening and explore the factors that affect their post-harvest ripening.
Understanding Cherry Ripening
Cherry ripening is a complex process that involves a series of biochemical and physiological changes. Cherries, like many other fruits, produce ethylene gas as they ripen, which acts as a ripening agent and stimulates the production of other ripening-related chemicals. The ripening process is also influenced by factors such as temperature, oxygen levels, and the presence of other fruits.
The Role of Ethylene in Cherry Ripening
Ethylene gas plays a crucial role in the ripening of cherries. As cherries produce ethylene, it triggers a cascade of reactions that lead to the breakdown of cell walls, the conversion of starches to sugars, and the production of pigments. This process is responsible for the characteristic sweet taste, tender texture, and vibrant color of ripe cherries. However, the production of ethylene is not unique to cherries and is a common feature of many fruits, including apples, bananas, and tomatoes.
Factors Affecting Cherry Ripening
Several factors can influence the ripening of cherries, including:
Temperature: Cherries ripen fastest at temperatures between 60°F and 70°F (15°C and 21°C). Higher temperatures can lead to over-ripening and spoilage, while lower temperatures can slow down the ripening process.
Oxygen levels: Cherries require oxygen to ripen. In low-oxygen environments, the ripening process can be slowed down or even halted.
Light exposure: Cherries can continue to ripen in the dark, but exposure to light can enhance the production of ethylene and promote ripening.
Do Cherries Continue to Ripen After They’re Picked?
Now that we’ve explored the basics of cherry ripening, let’s address the question at hand: do cherries continue to ripen after they’re picked? The answer is a resounding yes, but with some caveats. Cherries, like many other fruits, can continue to ripen after they’re picked, but the rate and extent of ripening depend on various factors, including the cherry variety, handling and storage conditions, and the stage of ripeness at the time of picking.
Cherry Variety and Ripening
Different cherry varieties have varying degrees of ripening potential after picking. Some popular cherry varieties, such as Bing and Rainier, tend to continue ripening after they’re picked, while others, like Montmorency and Balaton, may not ripen as much. The ripening potential of cherries is also influenced by the growing conditions and handling practices used during production and transportation.
Handling and Storage Conditions
The way cherries are handled and stored after picking can significantly impact their ripening potential. Cherries should be stored in a cool, dry place with good air circulation to slow down the ripening process. Exposure to heat, moisture, or ethylene-producing fruits can promote ripening and reduce the shelf life of cherries.
Practical Tips for Ripening Cherries at Home
If you’ve purchased cherries that are not yet ripe, don’t worry – you can still encourage them to ripen at home. Here are some practical tips to help you ripen cherries:
To ripen cherries, place them in a paper bag with an apple or banana, as these fruits produce ethylene gas, which can stimulate ripening.

Do cherries continue to ripen after they are picked from the tree?
Cherries, like many other types of fruit, undergo a ripening process after they are picked from the tree. However, the extent to which they continue to ripen depends on several factors, including the variety of cherry, the stage of ripeness when picked, and the conditions under which they are stored. Some cherry varieties, such as sweet cherries, are typically picked when they are fully ripe, while others, like sour cherries, may be picked when they are still slightly green and then allowed to ripen further after picking.
The ripening process in cherries is driven by a series of complex biochemical reactions, including the breakdown of starches into sugars and the production of ethylene gas, a natural ripening agent. After picking, cherries can continue to produce ethylene, which helps to stimulate the ripening process. However, this process can be slowed or accelerated depending on factors such as temperature, humidity, and oxygen levels. For example, storing cherries in a cool, dry place can help to slow down the ripening process, while exposing them to higher temperatures and humidity can speed it up. By understanding the factors that influence the ripening process, farmers and consumers can take steps to optimize the ripeness and quality of cherries.
What factors influence the ripening of cherries after they are picked?
Several factors can influence the ripening of cherries after they are picked, including temperature, humidity, oxygen levels, and exposure to light. Temperature is one of the most important factors, as high temperatures can accelerate the ripening process, while low temperatures can slow it down. For example, storing cherries at room temperature can cause them to ripen more quickly than storing them in the refrigerator. Humidity is also important, as high humidity can lead to mold and rot, which can prematurely spoil the cherries. Oxygen levels can also play a role, as some cherry varieties require oxygen to continue ripening, while others may be more sensitive to oxygen and require a controlled atmosphere to maintain their quality.
In addition to these environmental factors, the handling and storage of cherries can also influence their ripening. For example, cherries that are handled roughly or stored in a way that causes them to become bruised or damaged may ripen more quickly than those that are handled gently and stored carefully. Similarly, cherries that are stored in close proximity to other fruits, such as apples or bananas, may be exposed to higher levels of ethylene gas, which can stimulate the ripening process. By controlling these factors, farmers and consumers can help to optimize the ripening of cherries and maintain their quality for a longer period.
Can cherries be ripened at home after they are purchased?
Yes, cherries can be ripened at home after they are purchased, although the extent to which they will ripen depends on the variety and the stage of ripeness when purchased. To ripen cherries at home, it is best to store them at room temperature, away from direct sunlight and heat sources. A paper bag or a breathable container can help to trap ethylene gas and stimulate the ripening process. It is also important to check on the cherries regularly and remove any that are spoiled or overripe, as these can produce excess ethylene and cause the other cherries to ripen too quickly.
To speed up the ripening process, some people place the cherries in a bag with an apple or a banana, as these fruits produce more ethylene gas than cherries and can help to stimulate ripening. However, it is generally not recommended to wash the cherries before storing them, as excess moisture can lead to mold and rot. Instead, it is best to gently rinse the cherries just before eating them. By following these simple tips, consumers can help to ripen cherries at home and enjoy them at their best quality.
How can I determine if a cherry is ripe and ready to eat?
Determining if a cherry is ripe and ready to eat can be a bit tricky, but there are several signs to look for. One of the most obvious signs is the color, as ripe cherries are typically a deep red or yellow color, depending on the variety. The skin should also be slightly tender to the touch, but still firm enough to hold its shape. A ripe cherry should also be slightly sweet and tart to the taste, with a juicy texture.
To check for ripeness, gently squeeze the cherry between your fingers. A ripe cherry should yield to pressure, but still feel slightly firm. If the cherry is too soft or mushy, it may be overripe. It is also a good idea to check the stem end of the cherry, as a ripe cherry should come off the stem easily. If the cherry is difficult to remove from the stem, it may not be fully ripe. By checking for these signs, consumers can determine if a cherry is ripe and ready to eat, and enjoy it at its best quality.
Do all types of cherries continue to ripen after they are picked?
No, not all types of cherries continue to ripen after they are picked. Some varieties, such as sweet cherries, are typically picked when they are fully ripe and do not continue to ripen significantly after picking. Other varieties, such as sour cherries, may be picked when they are still slightly green and then allowed to ripen further after picking. The extent to which a cherry will continue to ripen after picking also depends on the specific growing conditions and the stage of ripeness when picked.
In general, cherry varieties that are high in acidity, such as sour cherries, tend to continue ripening after picking, while those that are lower in acidity, such as sweet cherries, may not ripen as much. This is because the acidity in the cherry helps to stimulate the production of ethylene gas, which drives the ripening process. By understanding the specific characteristics of each cherry variety, farmers and consumers can take steps to optimize the ripening process and enjoy the best quality cherries.
Can cherries be stored for a long period of time to prolong their freshness?
Yes, cherries can be stored for a period of time to prolong their freshness, although the exact length of time will depend on the variety and the storage conditions. In general, cherries can be stored for several days to a week when kept in a cool, dry place, such as the refrigerator. To store cherries, it is best to keep them in a breathable container, such as a paper bag or a mesh bag, to allow for airflow and prevent moisture buildup.
To extend the storage life of cherries, it is also possible to use controlled atmosphere storage, which involves storing the cherries in a sealed container with a specific mixture of gases, such as oxygen, carbon dioxide, and nitrogen. This can help to slow down the ripening process and prevent spoilage. Some commercial cherry producers also use modified atmosphere packaging, which involves sealing the cherries in a bag or container with a modified atmosphere to extend their storage life. By using these storage methods, consumers and producers can help to prolong the freshness of cherries and enjoy them for a longer period.
