Introduction to Tea Oxidation
For more tea tips, check out our tea guides.Tea oxidation is a process that transforms the flavor and color of tea leaves, resulting in a wide range of varieties. From green to black, each type of tea has its unique characteristics, shaped by the level of oxidation it undergoes.
Understanding Oxidation Levels
Oxidation occurs when the enzymes in the tea leaves react with oxygen, leading to a series of complex chemical reactions. The level of oxidation can be controlled by adjusting factors such as temperature, humidity, and the duration of the oxidation process.
Equipment Needed for Tea Oxidation
- Tea leaves
- Oxidation tanks or bins
- Temperature control devices
- Humidity control devices
- Withering trays or machines
Step-by-Step Tea Oxidation Process
- Harvesting: Fresh tea leaves are plucked from the tea plants.
- Withering: The leaves are spread out to remove excess moisture.
- Rolling: The leaves are rolled to release the enzymes that trigger oxidation.
- Oxidation: The rolled leaves are left to oxidize for a controlled period.
- Firing: The oxidized leaves are heated to stop the oxidation process and dry the leaves.
Pro Tips for Achieving Perfect Oxidation
- Monitor temperature and humidity levels closely.
- Adjust the oxidation time based on the desired level of oxidation.
- Use high-quality tea leaves for the best flavor and aroma.
