Types of Tea
Tea is generally divided into categories based on how it is processed.
Green, black, and oolong teas all come from the same plant, Camellia sinensis, but are prepared using different methods.
To produce green tea, fresh leaves from the plant are lightly steamed.
What is white tea?
White tea is the least processed of the three teas.
Because of this, it retains a high amount of antioxidants (2, 3).
This is thought to be one reason why studies have linked white tea with many health benefits such as:
- Reducing the risk of heart disease
- Combating skin aging
- Weight loss.
It also refers to one of several styles of tea which generally feature young or minimally processed leaves of the Camellia sinensis plant.
White tea is not rolled or oxidized, resulting in a flavor characterized as “lighter” than most green or traditional black teas.
White tea, like black and green tea, is made from the Camellia sinensis plant and contains polyphenols, a set of phytonutrients that are thought to be responsible for the health effects of tea
How Much Caffeine In White Tea?

Oolong is a traditional semi-oxidized Chinese tea produced through a process including:
Withering the plant under strong sun and oxidation before curling and twisting.
Most oolong teas, especially those of fine quality, involve unique tea plant cultivars that are exclusively used for particular varieties.
The degree of oxidation, which varies according to the chosen duration of time before firing, can range from 8–85%, depending on the variety and production style.
Oolong is especially popular in south China and among Chinese expatriates in Southeast Asia, as is the Fujian preparation process known as the Gongfu tea ceremony.
The Journal of Food Science recently tested several varieties of Oolong tea and they discovered varying levels of caffeine.
Caffeine In Oolong Tea
Oolong teas contain about 45 mg of caffeine per cup.
Oolong Tea Benefits
Oolong tea may not be as well known as green or black tea, but it has similar health benefits.
These include benefits for heart, brain, bone and dental health.

Two principal varieties of the species are used:
- Small-leaved Chinese variety plant, used for most other types of teas
- Large-leaved Assamese plant, which was traditionally mainly used for black tea
It is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process used to make oolong teas and black teas.
It originated in China, but its production and manufacture have spread to many other countries in Asia.
