The chart illustrates how black tea is manufactured through two different processes.
The process involves 3 main steps beginning with preparing tea leaves and finishing with releasing tea flavor and aroma.
The process of producing black tea starts by picking fresh tea leaves, the gatherer picks up only bud and top leaves for high-class tea. At the following step, these buds and top leaves are put on a rack to get withered by a fan with 60% moisture out.
The next main step of this process is producing tea which has been separated into two distinct methods. Starting with the traditional method called loose tea, the black leaves are rolled flat and broken to discharge enzymes. The modern one is bagging the leaves which are cut to make smaller granular pieces. The process is followed by fermentation which combines enzymes with air to change black leaves’s color to copper. Finally, the leaves which have 97% moisture out are dried in hot air dryers, releasing flavor and aroma.
