Quick Answer
Mulberries do not ripen after being picked. They are a non-climacteric fruit, meaning they do not continue to ripen off the tree.
Mulberry Fruit Identification
Mulberries are often mistaken for other fruits due to their similarity in appearance. However, they have a unique characteristic: a five-angled, pointed shape and a distinctive, slightly sweet taste. The most common varieties of mulberries include the Red Mulberry (Morus rubra), White Mulberry (Morus alba), and Black Mulberry (Morus nigra).
When to Pick Mulberries
The optimal time to pick mulberries depends on the variety, but generally, they are ready to harvest when they are fully ripe. Red mulberries, for example, turn from green to a deep reddish-purple color when ripe. White mulberries remain white but develop a sweet, slightly tart taste when fully ripe. Black mulberries turn from green to a deep purple-black color. Use the following technique to check for ripeness: gently twist the fruit from the branch, if it comes off easily, it’s ready.
Mulberry Storage and Post-Harvest Handling
After harvesting, store mulberries in a breathable container, such as a mesh bag or a paper bag, to maintain their texture and prevent mold growth. Keep them in the refrigerator at around 32°F (0°C) to extend shelf life. Mulberries are highly perishable and should be consumed within 1-3 days of harvesting.
