Chinese tea terroir and culture

Daye // Big-leaf

A learning journey into Chinese tea

The Daye course is the second part of our journey on Chinese tea, and requires a succesful attedance to the Xiaoye - Small Leaf course
With the Xiaoye course we learn how to dive into Chinese tea terroir and to culturally translate its complexity; with the Daye we focus on the most technical aspects around our beloved tea leaves, going in-depth on professional tasting, Chinese evaluating jargon, domestic (Chinese) and international markets, supply chain. 
We learn how a Chinese tea-professional researches, samples and evaluates a tea-leaf before purchasing it; what is the standard in terms of appearance, fragrance, taste, of each category of tea, and also what are their most common flaws and what caused them.

In this course the most important terms and categories are given in Chinese language, following the teaching of Xiaoye course. 
The goal of this course is to learn how to independently sample, evaluate and purchase a tea for your business, understanding its value and potential. 
At the end of the course, after a successful passing of the final exam, there is the optional possibility to obtain the official certification as Tea Professional recognised by the Chinese government.
