Storage is critical for green tea quality. Its deterioration leads to its color to change from green and bright to withered yellow, the liquid turns darkish yellow, losing fragrance and taste becoming bland. Absorption of foreign odors may greatly affect the quality. Therefore, it is important to learn how to store it.

Factors contributing to deterioration of green tea


Temperature is a major factor causing deterioration. Higher the temperature, faster will be the oxidization of the tea polyphenol, and consequently, quicker the deterioration.


Elements such as tea polyphenol in a tea leaf may be oxidized in conditions having around 20% oxygen in the air. Generally, the degree of deterioration is directly proportionally to the duration of its contact with the air.


Tea is a hydrophilic substance; therefore the moisture content in a tea leaf will also increase when stored in a place with high moisture. Many elements contained in a tea leaf are hydrophilic compounds which may cause molding and accelerate deterioration.


Due to photosynthesis, pigments and esters contained in a tea leaf may produce some foreign odors.

Foreign odors

Storage after deoxidation

Green tea cannot be vacuum-packed because it may break the dried tea. and consequently, affect the appearance which is critical to the quality. However, deoxidizer placement and nitrogen-filling ways of deoxidation can be adopted for green tea storage.

Storage with dry lime

Pack the tea In air-permeable papers. Keep dried lime in a doth bag and place at the center inside the pottery jar. Put the tea around the bag. and finally place the jar in a cool and dry place. Check the lime regularly and replace when it is found to be moisturized. This is the traditional way to store Long Jing tea

The principle of green tea storage is ‘low temperature and moisture and avoidance of light, oxygen and foreign odors* However, the tea bought home must contain 6% moisture, otherwise it detenorates In caso of large quantities, it must be packed in small units for the convenience of drinking or storage Furthermore it is recommended that the same package be used for the same variety and quality tea otherwise the quality may be affected.
