The diagram below shows two different processes for manufacturing black tea.

The figure illustrates two methods of black

tea

production.

Overall

, it is possible to produce the

tea

through traditional or modern processes and each one has special advantages. The differences of the methods are at the middle

stage

where the dimension of the dry

tea

leaves are formed. In the first

stage

, the

tea

leaves are picked from the tree. In order to improve the quality of

tea

, just a few top leaves and buds are picked.

Then

at the withering

stage

, fans pass the air through leaves that keep on the rack.

This

step continues until the moisture declines by 60%. In the next

and Enzymes are released. The second method, which is faster and granular pieces become smaller, is called cutting.

The next step is

known as Oxidation leaves are spread and rolled on tiles. At

this

time because of the combination of Ensymes and air the colour of leaves changes to coppercolour.

Finally

, the

last

step is drying which is used in order to release the flavor and aroma of leaves.
