What Is Mold?
Mold is a type of fungus that grows in damp and humid environments. It can grow on a variety of surfaces, including food and beverages like tea. Mold spores are present in the air around us and can easily find their way onto food and drink, especially if they are not stored properly.
Mold can come in a variety of colors, including green, black, white, and yellow. It can also have a fuzzy or slimy texture, depending on the type of mold. Some molds are harmless, while others can be toxic and cause health problems.
When it comes to tea, mold can grow on the leaves if they are not stored properly. This can happen if the tea is exposed to moisture or if it is stored in a humid environment. Moldy tea can have a musty or earthy smell and taste, and it can be harmful to consume.
It’s important to note that not all tea will get moldy. Proper storage and handling can help prevent mold growth. If you suspect that your tea has mold, it’s best to discard it and purchase a new batch to ensure your safety and enjoyment.
How Mold Develops
When it comes to tea, mold can develop in a few different ways. Mold spores are everywhere, and they can easily find their way into tea leaves during the growing, harvesting, and processing stages. Once mold spores are present, they can quickly grow and spread if the conditions are right.
One of the most common ways that mold develops in tea is when the tea leaves are not properly dried. If the leaves are too moist, they can become a breeding ground for mold. This is why it’s important to dry tea leaves thoroughly before packaging and storing them.
Another way that mold can develop in tea is if the tea is stored in a damp or humid environment. Moisture is a key factor in the growth of mold, so it’s important to keep tea stored in a dry place. If you live in a humid climate, consider using a dehumidifier to keep the air dry.

In some cases, mold can develop in tea bags or loose tea that has already been brewed. This can happen if the tea is left out for too long or if it’s not stored properly. To prevent mold from developing in brewed tea, make sure to store it in an airtight container in the refrigerator.
Overall, mold can develop in tea if the leaves are not properly dried, if the tea is stored in a damp environment, or if brewed tea is not stored properly. By taking the proper precautions, you can help prevent mold from developing in your tea.
