Saw a question on line today about the sun drying tea.
Often a tea will be described as having the virtue of being ‘sun-dried’. It sounds very wonderful, natural and romantic – conjuring up a sense of gourmet quality in the same way that sun-dried tomatoes do. The sun is free, although unreliable, and is an energy that has been around since tea was first made but does sun drying produce a better tea compared to other forms of drying; or is it just fluffy marketing? And if it does improve quality, why is this?
First of all, it’s important to establish some basic clarity for Withering process in the tea production process:
- Not all teas are suitable for sun dried (it is a Solar Dried process also known as Daylight Withering ) approach.
- Basically the withering process is a process for oxidation. The management of oxidation process (also known as Withering Process) plays an important role to simulate for the fermentation process. The oxidation process will not be stopped completely by the Daylight Withering process, because the oxidation process can only be stopped by applying extra heat to the leaves in order to deactivate the oxidative enzymes present in tea leaves.
- Sun Dried (or Daylight Withering ) is a very traditional and yet a must technique used for (some) White Tea, Oolong, (some but not all) Black tea and Pu’erh. Withering is also an important step for green tea, but the chance to use the Daylight Withering is less; because the color of fresh leaves will get dull and greyish in the Withering process with daylight.
- Indeed sun is a free of charge energy but not reliable; and its strengths are varied in different time in a day or in season. So which tea has to go through how long in the Daylight Withering process, it depends on the timing when freshly pluck tea leaves are back to the production site and the strength of the sun; and most of all, which tea are to be produced?
- For Chinese tea, the first and utmost definition for “Quality” are
- Fresh tea leaves are hand pluck
- Each process is well and thoroughly managed
- A lot of machines are used to aid the process but can’t replace the experienced workers.
- Basically there are different drying processes in tea production processes,
- Outdoor oxidation and fermentation process, i.e. either solo or mixture of Daylight- and Shadow Withering
- Various indoor processes
