Tea processing

TEA FACTORY – The Tea Manufacturing Process

A marvelous taste takes extra effort!
To produce fine teas, it takes professional tea masters to meticulously control every step. From tea bushes to tea leaves, every step of processing tea is time-consuming and labor-intensive.


1.Hand picking is used to preserve the original flavor
Modern tea plantations have two ways of harvesting: machine picking and hand picking. Though machine picking is efficient, it tends to destroy the completeness of tea leaves, and old leaves are usually plucked along with the new ones, leaving a batch of mixed-quality leaves. To produce teas with the highest quality, YunFang Tea Plantation adopts a comprehensive hand-picking method, which is the most time-consuming and labor-intensive. We only pick the new leaves and eliminate the old leaves, and we preserve the shape of leaves so that they can fully expand in the water, which is the basis of fine teas.
2. Precise withering process: sun withering and indoor withering
Plucked tea buds need to go through a process called sun withering, which means exposing leaves under the sun so that the moisture inside tea buds will evaporate. Since air comes into contact, the oxidization process begins. After the sun withering process, light green leaves will turn to darker shades of green, and leaves will become limp due to the lack of water. After this process, tea leaves are placed indoors, and a mixing process will be conducted to break down partial marginal cells of tea leaves so that the air can enter the leaves and help with fermentation.
3. Proper fermentation can maintain moisture and stabilize the fragrance
The degree of fermentation is the key to determining the taste of the tea. Fast fermentation will cause leaves to lose too much moisture, resulting in a bland taste; slow fermentation results in too much moisture, so the tea tastes too bitter and heavily influences the quality of the tea.
4. Roasting at high temperatures so fermentation stops at the proper point
After continuing fermentation, if we wish to stop the fermentation process, another action called “roasting” will be conducted to kill enzyme activity so that the fermentation can stop when the moisture can be best preserved. This process can get rid of the bad taste so that the fragrance can gradually develop.
5. Rolling, so the fragrance can be released immediately in hot water
In order for the tea fragrance to be released immediately in hot water, a rolling process is needed after the roasting process. Complete tea leaves will curl and shrink because of the rolling process. As well, due to the pressure of rolling, the moisture inside the leaves will be squeezed out and then attached to the surface; and after hot water passes through, the leaves can dissolve quickly in the water because of the rolling process.
6. Drying ensures blocking fermentation and keeping moisture below 5%
To completely block rolled leaves from fermentation and to shrink them for easy packaging and preservation, there will be a drying process after the rolling process, which applies high temperatures to destroy the enzymes in the leaves, and keeps the moisture below 5%. There will be two stages in the drying process to ensure that the leaves are completely dry. The teas at this stage are called “raw teas (crude teas)”.
7. Sifting out the best: the refining process
After raw teas are produced, a refining process will be conducted to ensure the tea quality after sales. First, we sieve the leaves, and then we use a cutting machine to cut thicker or coarser leaves into proper sizes for easy classification. After that, we discard the stems and use a blower to blow off the scraps. Step by step, the refining process standardizes the tea quality.
8. Proper baking produces the original fragrance
Refined tea leaves go through a final stage of slow baking so that they can release the original fragrance. Generally speaking, different kinds of teas undergo different ways of baking to preserve the best flavors: low heat (fresh tea), medium heat (medium-mature tea) and high heat (mature tea). Their fragrance and taste all differ, and they have their own loyal fans.
9. Refined Packaging
Our tea is vacuum-packed and sealed, ensuring that the highest quality is preserved. We also provide refined packaging which will surely be your ideal gift!
