Oolong tea

Oolong tea, also known as wulong, translates to “black dragon” in Chinese and is a semi-oxidized tea. Oolong actually lies perfectly between green and black teas. Its semi-oxidized nature grants it an incredible depth of flavor, ranging from light and floral to dark, woody, and roasted varieties, making it a delightful choice for tea enthusiasts.

One of the unique qualities of oolong teas is their ability to endure multiple infusions, with some varieties lasting through ten or more brews in a single session. As you sip your oolong, you’ll often find that the flavors become more pronounced after the third infusion, revealing the true beauty of this tea.

We recommend enjoying your oolong “gong fu style” by brewing it in small vessels like a gaiwan or clay teapot and savoring each moment mindfully. You’ll soon understand why oolongs are considered some of the most sought-after artisanal teas in the world.

To brew oolong tea it’s best to use very hot water, ideally around 90°C. Steeping time, water temperature, and tea-to-water ratio can vary based on personal preference.

We recommend trying this tea out by following gong fu brewing: using small tea vessels and multiple infusions. A good utensil for oolong tea would be a porcelain gaiwan or a clay Yixing teapot. The latter, in particular, if used over a long period of time will develop its own tea oils and bring out more depth out of each oolong tea brewed.

Then we have cold brewing, which can accentuate the sweetness and fruity notes in a lot of oolong tea varieties.

If you’re unsure about the brewing process, visit our website or the packaging for detailed tea guidance. Ultimately, we encourage everyone to experiment and discover the method that best suits their taste.

Like all other tea types, oolong tea production originated in China, dating back nearly 1,000 years to the Song Dynasty (960 – 1279) in the Fujian province. Due to its exceptional quality and flavor, this tea was the first to be designated as a “tribute tea,” crafted specifically for the royal court.

Its renown spread throughout China, maintaining its prestigious status as a tribute tea during the Qing Dynasty (1636 – 1912). Today, the primary production regions are Fujian (notably the Wuyi Mountains and Anxi County), Guangdong, and Taiwan.

Prominent oolong teas from the Wuyi Mountains are known as “rock or cliff tea” (yancha), featuring varieties such as Big Red Robe (Da Hong Pao), Cassia (Rou Gui), and Narcissus (Shui Xian). Anxi is celebrated for its Iron Goddess of Mercy (Tie Guan Yin). In Guangdong, the Phoenix Mountains (Feng Huang) are renowned for producing the floral and fruity Dan Cong teas, also known as Phoenix oolongs.

In Taiwan, the varied climate and geography produce unique oolongs such as Frozen Summit (Dong Ding), Oriental Beauty (Dong Fang Mei Ren), Alishan, Bao Zhong, and Four Seasons (Si Ji Chun), among others.

While most producers market oolong teas under common names like Tie Guanyin, Dong Ding, and Dan Cong, connoisseurs classify and appreciate oolong based on its region, age, bush variety, and harvest season, much like fine wine.

At Tea Kulture, sustainability and fair trade are at the heart of everything we do. We partner directly with farmers in the world’s prominent tea-producing regions who cultivate tea using natural, eco-friendly practices.

By ensuring fair wages and ethical working conditions, we support both the people and the planet. Our direct trade approach allows us to bring you premium-quality tea leaves while maintaining a commitment to fairness and environmental responsibility.

Crafting high-quality oolong tea demands exceptional skill and precise techniques. This tea is celebrated for its versatility, offering flavors that can range from delicate and floral to deep and roasted, depending on the processing methods applied.

The production process is one of the most intricate of all tea varieties, with each step meticulously carried out to develop the tea’s unique characteristics:

• Harvesting: the leaves are plucked by the farmers.
• Withering: the tea leaves are left indoors or outdoors to wither and lose moisture.
• Bruising/oxidation: the tea leaves are gently shaken and bruised to initiate the oxidation process. This is a crucial step in oolong tea production. A light oxidation will result in greener, more floral oolong varieties; while a stronger oxidation will leave us with darker, more robust varieties, almost akin to black tea.
• Fixation: to stop the oxidation process the tea leaves undergo heating methods such as pan-firing or steaming.
• Rolling: the tea leaves are rolled into a desired shape. This process is crucial for releasing the tea leaves’ natural oils. The shapes can vary from long and curly loose leaves like those of the Dan Cong varieties; or “wrap-curled” into small beads which is more common amongst oolongs in Taiwan.
• Roasting: this is an optional step where some teas are roasted or baked to give them a delightful nutty, caramel-like sweetness.

The debate surrounding tea’s potential health benefits is a common topic of discussion. Tea has a rich history intertwined with medicinal uses, but modern wellness trends have prompted increased scrutiny of these claims.

For example, oolong teas are sometimes used in Traditional Chinese Medicine. Since they lie somewhere between green and black teas, oolong teas possess a good balance of both warming and cooling qualities. However, claims of tea curing cancer, heart issues, or arthritis warrant caution and further investigation.

Tea indeed contains beneficial compounds like polyphenols (antioxidants), L-theanine (an amino acid), and alkaloids with physiological effects. These elements contribute to tea’s potential health benefits, yet concrete health outcomes remain uncertain.

At Tea Kulture, we advocate for appreciating tea as a healthy practice with positive effects, rather than solely as a medicinal remedy.

The average caffeine content of oolong tea is typically 30-50 mg/cup. In comparison, an average cup of coffee contains about 95 mg of caffeine.

However, it’s important to keep in mind that several factors influence the caffeine levels in tea, including the natural environment, fertilization practices, the specific part of the plant harvested, seasonal variations, and the brewing time.

Oolong tea, made from the Camellia Sinensis plant, contains a moderate amount of caffeine, which may interfere with sleep if consumed later in the day. If you’re sensitive to caffeine, it’s wise to avoid drinking oolong tea in the late afternoon or evening, as it might make falling asleep more difficult.

For a soothing, caffeine-free alternative, consider herbal infusions like chamomile or rooibos. These teas are naturally calming and promote relaxation without the stimulating effects of caffeine.

Properly storing tea is crucial to retain its freshness and flavor.

To preserve your oolong tea leaves, place them in an airtight, opaque container to shield them from oxygen, which may lead to oxidation and compromise their aroma. Store your tea in a cool, dark location, away from sunlight and heat sources.

Ensure the storage area remains dry to prevent moisture absorption, which can degrade the tea’s quality. Avoid placing your tea near strong odors to prevent flavor contamination.

By investing in high-quality tea leaves and storing them correctly, you can prolong the retention of their intricate flavors for extended periods.
