Tea is by far the most popular drink of the majority of people. It has a huge variety but two types that are very popular around the world is Black Tea and Green Tea.

What is Black Tea?

It is characterised by a strong aroma and high caffeine. It is fully oxidised and then it is ready to be used. The process involves cutting the whole leaves of the tea plant when they are at peak of freshness and then it is given time to wither naturally so that water content in leaves is reduced. After this, the leaves undergo the process of fermentation so that it dries and oxidises completely. This result in a change in the chemical composition of leaves, due to which it becomes dark and has a strong aroma and taste.

What is Green Tea?

Green tea is also manufactured in approximately the same way as black tea but there is a difference in the duration of fermentation. First, the green tea leaves are allowed to wither slightly then they go through the process of pan drying, oven drying or steaming to stop oxidation. As there is no fermentation involved the green colour is retained and the flavour is light or earthy.
