Oolong Tea 101. Tea Types – Benefits – Brewing.

Oolong tea, made from the leaves of the Camellia sinensis plant which also gives us black and green tea is a traditional semi-oxidized tea made by withering the plant in direct sunlight and then oxidizing it before curling and twisting it. Oolong tea is neither a black nor a green tea and is often classified as a distinct form of tea. This is due to the oxidation and shape of the leaves.

The process of oxidation causes the green tea leaves to turn into a deep black colour. Green tea isn’t allowed to oxidise much, but black tea is oxidised until it’s completely black. Since oolong tea is halfway between the two, it is partly oxidised. The flavour of oolong tea can vary greatly. Depending on the horticulture and style of processing, they can be sweet and fruity with honey aromas, woody and dense with roasted aromas, or green and fresh with complex aromas. While different oolong varieties are processed differently, the leaves are typically shaped into one of two styles. Some are ‘wrap-curled’ into small beads with tails, while others are rolled into long curly leaves. 

Types of Oolong Tea:

  • Dao Hong Pao: Da Hong Pao which originated in the Fujian province of China is green and brown in colour and has the appearance of tightly knotted ropes or slightly twisted strips. It has a unique orchid fragrance and a long-lasting sweet aftertaste. After brewing, the tea is orange-yellow, bright and clear. In comparison to other teas, Da Hong Pao can be steeped nine times without losing its taste.

  • Dong Ding: Dong Ding is an Oolong tea from Taiwan. It gets the name from its namesake mountain where it is cultivated. Its cultivation roots back to 150 years when it was first brought from China’s Fujian Province. It is usually 15-30% oxidized, sometimes over charcoal giving the tea a toasty, woody flavour.
  • Darjeeling Oolong: This variety of Oolong originates in Darjeeling, India. After rolling, the leaves are allowed to oxidise on trays before being fired to reduce the moisture level to about 2% and seal the ruptures, which will be reopened with hot water from the customer.
  • Assam Smoked Oolong: Assam Smoked Oolong is a highly unusual and rare oak-smoked tea from Assam, India. The liquor has a lovely smoky aroma. The empyreumatic, sweet and malty character has notes of apricots and tobacco. Its aroma is very similar to a good single malt whisky.

A cup of brewed Oolong tea contains approximately 36 mg of Caffeine which may vary based on the region and production process. A mildly oxidised oolong (similar to green tea) may have lower caffeine levels, whereas a heavily oxidised oolong (similar to black tea) may have higher caffeine levels.
