What is the meaning of the numbers on the back of green tea boxes?
There are 4 or 5 digit numbers on the back of each green tea box. I know they are used to classify the type of tea and its quality, but I have never found how to read them. How do I figure out which one is higher quality than another one.
Here are examples:
Chunmee tea Series:
41022AAAA, 41022AAA, 41022AA, 41022, 4011, 9371, 9370, 9369, 9368, 3008, 34403
Gunpowder Tea Series:
3505A, 3505B, 3505C, 9372, 9373, 9374, 9375, 9475, 9575

Doesn't matter which brand. These numbers indicate exactly which tea and which grade of the tea has been used. It is part of the ISO9001 certified tea trading companies in China.
Similar to ingredient lists, the most used item comes first. This blend of green tea uses several grades and series of leaves of chunmee, from the highest grade to intermediate grades.
The same goes for the gunpowder tea.
The reason it's so hard to find info on the Internet is because it's chinese. But you can rest assured it means you are get good quality and reliable tea.
