Oolong Tea vs. Darjeeling Tea: What’s The Difference?

Tea drinkers can choose from many different types of tea, including black tea, Earl Grey, Pu'erh tea, and white tea. In this article, we discuss Oolong Tea vs. Darjeeling Tea.

What is Oolong Tea?

A traditional Chinese tea made from the Camellia sinensis leaves, oolong tea, grows in tea gardens. Camellia sinensis is used to make both black tea and green tea, depending on how the leaves are processed.

A chemical reaction called oxidation occurs when enzymes in the tea leaves turn the green leaves to a deep black color. Oolong tea is partially oxidized.

What is Darjeeling Tea?

This Indian tea also comes from the Camellia sinensis; however, the variety is different. Teas grown in India are harvested from the Camellia sinensis var. assamica. To be certified, Darjeeling tea must be grown in the geographic district by the same name at the foothills of the Himalayas. Darjeeling is referred to as “the champagne of teas” because of its high quality and fruity essence.

Darjeeling is recognized by tea aficionados specifically for its muscatel flavor and tastes less astringent than most black teas.

The Camellia sinensis grows new leaves and is harvested five times each year. These cycles are called flushes. Major flushes occur:

  • Mid-March to May
  • June to mid-August
  • October to November. 

Minor flushes occur:

  • During the two weeks between the first and the second flushes
  • Between the second and the third flushes during monsoon.

These periods are not fixed and depend on the weather. Excess rainfall earlier than expected may increase the length of the rain flush by a few weeks while reducing the period of the second flush. Different flushes can result in color, aroma, and taste variations. 

The difference in black, oolong and green tea leaves derive from tea fermentation. Flavonols in the tea leaves combine with oxygen during the fermentation process. 

  • Darjeeling green tea is not fermented. 
  • Darjeeling oolongs are semi-fermented. 
  • Darjeeling black tea undergoes full fermentation.

Health Benefits of Oolong Tea

Reports have shown a connection between lower cholesterol levels and drinking oolong tea. After a month's oolong consumption, patients noticed a significant reduction in the arteries' narrowing and hardening, and researchers attributed the improvement to the polyphenols and catechins in this tea.

Oolong tea contains amino acids that help prevent the release of caffeine. It also contains catechins and antioxidants that fight toxins and free radicals that can cause oxidative stress and damage healthy cells.

Health Benefits of Darjeeling Tea

Darjeeling tea is rich in flavonoids, namely, thearubigins and theaflavins, that help keep arteries free of fat. This tea enables the body to receive and absorb nutrients from the diet.

Regular consumption of Darjeeling tea can help improve heart health Darjeeling tea helps reduce stubborn body fat through polyphenols. The availability of these extensive components helps break down fat and provide energy to the body.
