What is Oolong Tea?

Oolong (乌龙 wūlóng) tea is a variety of tea derived from the Camelia Sineses plant - just like Black Tea, Green Tea, and White Tea. It is partially oxidized by letting the leaves wither in the hot sun before processing. Black teas are fully oxidized, white teas are not oxidized at all, and oolongs are semi-oxidized, between 8-80%.

Oolongs can vary widely in taste, from sweet and fruity, to dark and roasted, to green and fresh with complex aromas. Much care is put into the process to create oolong teas, and they are often some of the most prized teas to drink. Generally speaking, there are two types: Green Oolong, and Dark Oolong. 

Green Oolongs (sometimes referred to as Jade oolongs) have a much lower oxidation level, and are more similar to green teas. The leaves are green in color, and the resulting tea is often light and flowery. Dark oolongs have heavier oxidation levels, closer to that of black tea. 

 

What's special about oolong tea?

Great care is required to produce oolong teas. If oxidized for too long it will become a black tea. Too short and it will be a green tea. As such, oolongs are usually high quality with more robust flavors. Some ancient oolongs have very low supply and are thus very expensive, such as Da-Hong Pao which reaches prices of $1.2 million per kilogram.

Where does oolong tea come from?

Oolong teas are grown in China. The oldest region is Fujian, which is split into Anxi County and Wuyi Mountains. Oolongs are also grown in Guangdong (pheonix oolong), and Taiwan.

  • Tieguanyin: Muzha Tea Co. brought the tea from Anxi County and developed Taiwan's own variation of the popular tea on the hills of Muzha area near Taipei. While the techniques they used were similar to Anxi tieguanyin, the tastes have evolved during over a century of development.

Can I drink oolong everyday?

Yes! You can drink a minimum of 2-3 cups per day. Keep in mind that Oolong teas do contain caffeine. Always seek professional medical advice if you notice any adverse side effects to drinking tea.

How do you properly drink oolong teas?

The steeping style can vary depending on personal preference and brewing style. If you are new to oolongs and steeping western style (not gonfu), you can try these preparation instructions:

Green (Jade) Oolong: 2-3 minutes, 180° F water temperature
Dark Oolong: 2-3 minutes, 200° F water temperature

Don't forget to re-steep your tea! Since they are typically of higher quality, oolongs can be re-steeped several times, bringing out additional complexities and flavors. You can reuse your tea leaves at least three times, sometimes much more.

What are some health benefits of oolong teas? *

Oolong teas have many studied health benefits.

Brain Health

Oolong tea contains epigallocatechin gallate (EGCG), according to a research review. EGCG is one of the healthiest components of green tea that gives it many of its benefits — like helping to prevent memory loss and cognitive decline.

Regulating Blood Sugar

Oolong tea, like green tea, may help improve blood sugar control, according to a research review and meta-analysis. Some studies have found a link between oolong tea and lower fasting blood sugar levels. Better blood sugar control can help reduce your risk of type 2 diabetes, unwanted weight gain, and heart disease.

Strengthens Bones

One study found that women who drank 1-5 cups of oolong tea daily had much higher bone density than non-tea drinkers.

Reduces Cholesterol

One study in mice who were fed until they had excess weight found that oolong tea could improve these animals’ cholesterol and triglyceride levels, potentially decreasing their risk of heart disease.

Decreases Stress

Stressed out? One small study found that sipping on oolong tea could decrease heart rate variability, a measure of short-term stress, in college students.
