What Is Oolong Tea?
For many, the best Oolong tea looks similar to a typical black tea. For others, it is closer to a green tea. Oolong tea, however, is not a black or a green tea. In fact, Oolong tea is a category of tea all by itself.
What makes this a little confusing is that depending on the processing of the tea, an Oolong tea can end up with more green tea or black tea characteristics. Here are a few main characteristics that determine what sets Oolong tea apart from the others…
The amount of oxidation during processing is what determines what variety of tea will be produced. Black tea is fully oxidized. Green tea is barely oxidized. Oolong tea is partially oxidized.
While this is a general difference, Oolong teas can be oxidized between 8 and 80-percent, depending on the tea master’s particular production style. The amount of oxidation plays a role in the overall flavor of the finished product.
One more factor that sets Oolong teas apart from black or green tea is the way the leaves are shaped during processing. Oolong teas are typically curled, twisted or rolled into strands or balls.
The final flavor of the Oolong tea is impacted by the shaping technique used. The rolling also contributes to the color, aroma and visual appearance of the tea.

Oolong Tea Production
There are a total of seven steps that Oolong tea leaves follow during processing:
After the tea leaves have been harvested, they are spread out indoors or in the sun outdoors. This softens the leaf cell walls and pulls moisture out of the leaf cells to evaporate. This begins the natural enzymatic fermentation of the tea leaves.
Turning Over or Tossing/Bruising
Machines are used to ‘shake’ the now dried tea leaves. The action breaks them down which mixes the chemical elements that exist in the stems with that of the leaves. This improves the oxidation and balances tea flavor by removing bitterness.
Oxidation (Partial and Full)
The leaves are left alone at this point to allow for them to continue the fermentation process. It is at this point where tea masters decide on how much time the leaves can be left to oxidize. The amount of oxidization will impact flavor.
The leaves continue to break down during oxidation and can turn to a dark green or possibly a reddish tint. This is also the point in the processing where the tea leaves will develop taste characteristics that can range from flowery or fruity to grassy.
Fixing or Kill Green
Steam is used in various methods to halt the natural fermentation without damaging the tea leaves. Hand pressing with a hot pan and baking the leaves are other methods used to “kill (the) green(ing)” associated with fermentation.
Rolling or Forming
Hot or cold rollers are used where the tea leaves are passed. This breaks them down further and will establish what shape the leaves will end up with. The shaping of the tea leaves will have an effect on the tea flavor and is usually selected by the tea master during this step.
By using one of many different drying techniques, ranging from pan heating and hot air to sun drying, this step establishes the final moisture content of the tea leaves. This process also stops fermentation, prevents mold development and eliminates any grassy taste from the leaves.
A fruity or smoky flavor is added to the leaves through the roasting step known as firing. Leaves are roasted in a basket or pan with either electric heat or charcoal to finish them off before packaging for the market.
Oolong Tea History and Growing Regions
The history of tea dates back to 2,000 BC when it was common for residents in the Yunnan region of China to eat raw tea leaves from the Camellia sinensis plant. They began boiling the leaves to make a hot beverage in 1,000 BC.
By 25 AD sun drying became a method used to prepare the tea leaves for consumption. It was in the year 600 when semi-fermented tea was developed in the Fujian region of China. Steaming techniques were developed for green tea around the year 700 and tea was introduced to Japan in 815.
Green tea was first fermented in 1100 and that led to the establishment of the first tea houses in China. White tea soon followed and in 1271 the Royal Tea Baking Department was formed by the Yuan Government. In Fujian, oxidized black tea was developed in 1368.
Within 30 years, semi-fermented tea is developed in the Wuyi region of Fujian. The tea explosion took traction in the 1500’s and 1600’s when traders from other parts of the world arrive in China and export tea to their homeland.
In 1725 Oolong tea is developed in the Wuyi region with Silver Needle Pekoe White Tea following 40 some years later. Later in the century, the British trade Indian grown opium for tea and Oolong tea is introduced to Taiwan.
Over the next two centuries, many varieties of tea are developed including Silver Needle White Tea in 1885 and White Peony White Tea in 1922. China exports their first white tea in 1968 and the development of Black Pu-Erh Tea takes place in 1973.
Growing Regions of the Best Oolong Tea
China and Taiwan are the leaders in Oolong tea production in the world. However, they are not the only places it is produced. India and Thailand contribute to the production of this product but not in the high volume that comes from China and Taiwan.
There are three regions in China where Oolong tea is primarily produced. Darker Oolong teas come from the northern Fujian province and the Wuyi Mountains in particular. These Wuyi teas have a twisted leaf shape.
In the southern Fujian province, Anxi country is another producer. Anxi Oolong teas are characterized by leaves that are tightly rolled into round pellet-like shapes.
There are other oolong teas produced in regions near Anxi as well as the Phoenix mountain part of the Guangdong province. Smaller amounts of Oolong tea is produced in other parts of China.
Taiwan is well known for Oolong tea production with several varieties produced. The Dongding mountain area in Nantou County is where Dongding Tea comes from. It has a short fermentation process and a 40-minute charcoal roasting that gives the tea a nutty, caramel and chestnut flavor.
High Mountain Teas are the majority of varieties produced in Taiwan. Elevation plays a large role with some Oolong teas grown at 1,000, 2,200 and 2,500 meters or more. The higher the altitude usually translates to a higher cost to purchase with 500 grams priced up to $500 USD.
Other Growing Regions
India produces several tea varieties, most notably black teas. However, the Darjeeling region in West Bengal is known for a high altitude Oolong that has a unique flavor and aroma resulting from the topography. Darjeeling-like teas also come from neighboring regions.
Thailand one of the top ten producers of tea in the world. Although the actual volume is far less than other tea producing countries, Thailand creates high-quality teas including Oolong tea. Some of these teas happen to be the most expensive ones produced.
Oolong Tea Health Benefits

Oolong Tea for Weight Loss
The metabolism of fat in the body can be impacted by the polyphenolic compound found in Oolong tea. By drinking Oolong tea, the compound triggers specific enzymes that increase the body’s metabolic rate. Increased metabolism burns fat cells which in turn can lead to weight loss.
See this article for some more information on a study into Oolong tea consumption for weight loss.
Another benefit contributed to the polyphenol molecule that is produced during the oxidation phase of Oolong tea, it activates many different enzymes. One such enzyme is lipase. Not only does this increased metabolism, but it also reduces cholesterol levels and promotes heart health.

The concentrations of magnesium and calcium found in Oolong tea leaves can protect your bones. When your body has enough of these minerals going into it, you are able to fight the early signs of osteoporosis and retain proper bone density as a result.
Oolong tea contains anti-cancer properties resulting from the antioxidant flavonoids in the leaves. These flavonoids prevent cellular damage because they help to strengthen your immune system. A strong immune system is able to fight off infections more effectively.
If you are in need of a natural stress buster, Oolong tea may be your answer. The polyphenols and other nutrients are responsible for blocking receptors in the brain. The blocking action reduces the excitement inducing activity triggered by cortical neurons which reduce stress.
Unless it has been decaffeinated, Oolong tea contains caffeine. However, the amount of caffeine is dependent on a few factors. They include the specific plant variety and how long the leaves have been left to age.
Generally speaking, Oolong tea contains less caffeine than black but more than green teas. But as noted above, this depends on the specific Oolong tea variety and brand.
