About Mamancy Oolong Tea

Premium loose leaf teas and chocolates made in the Pacific Northwest.


At Mamancy Tea, we are passionate about creating the best teas possible. We believe that exceptional tea begins with high-quality tea leaves, which is why we source from small tea gardens in Kenya – where founder Anne was born and raised.

Once our quality tea leaves are harvested, we focus on skillfully processing them to preserve all of the complex and rich flavors that Oolong has to offer. Moisture is particularly important when handling Oolong tea, so experienced tea masters use the look, feel, and smell of the leaves to keep them at the perfect moisture level for ample flavor.

Oolong tea is a traditional Chinese tea that comes from the Camellia sinensis plant. This tea is considered to be the most challenging type of tea to produce, and its flavors are hugely impacted by the way the leaves are processed. While green tea leaves are minimally oxidized and black tea leaves are very oxidized, Oolong falls somewhere in the middle. Depending on the level of oxidization, Oolong tea can have flavors ranging from floral to earthy, light to full-bodied, and sweet to toasty.

History of Oolong Tea

Near the beginning of the Qing Dynasty (1644), Oolong tea emerged as a new style of partially oxidized tea from the Wu Yi Mountains in China. The unique curling leaves resemble the distinctive twisting bodies of mythical Chinese dragons, which earned the tea the name “Wu Long” – meaning “Black Dragon”. 

As Oolong tea rose in popularity, it spread all throughout China and beyond. In the mid-19th century, it was brought to Taiwan, which now has a reputation for producing some of the finest Oolong varieties in the world. Today, this extraordinary tea is enjoyed all over the world.

Health Properties of Oolong Tea

  • Encourages heart health
    Similar to green tea, Oolong tea is full of antioxidants that have been linked to reduced blood pressure and cholesterol levels – which are two of the leading causes of heart disease. Because of these compounds, Oolong tea can improve heart health over time.
  • Promotes tooth and bone strength
    Oolong tea contains polyphenols, which are antioxidant compounds also found in natural foods like dark chocolate, strawberries, and red wine. Some studies have indicated that these polyphenols can increase bone mineral density and strengthen tooth enamel.
  • May improve brain function
    Oolong tea contains theanine, which is an amino acid that can help boost focus while decreasing anxiety levels. Theanine can also impact serotonin and dopamine levels, which may reduce hyperactivity in individuals with ADHD.
  • Can boost weight loss
    Some studies indicate that Oolong tea can be beneficial for weight loss. Oolong tea contains a compound called catechin, which can help you break down and burn off fat more efficiently.
  • Moderate caffeine levels
    Oolong tea contains a moderate amount of caffeine. Though not everybody has an adverse reaction to caffeine, it may cause anxiety, poor sleep, or worsened symptoms of depression in some people.

How to Prepare Oolong Tea

How you prepare your cup of tea can impact how well the flavors come through. To ensure you are enjoying all of the delicate and complex flavors that herbal tea has to offer, here is a guide on how to prepare your tea:

  • Use filtered water at 180°F – 190°F. Poor quality water can mask the deep and complex flavors of Oolong tea, so it is important to use filtered water. The temperature of your water also determines how the compounds in the tea are released, so for best results it is ideal to use water that is between 180°F – 190°F.
  • Use a heaping teaspoon (~3g) of tea per 6oz cup. Flavor and taste can differ significantly depending on the specific tea, so you can add a little more or less depending on your personal preferences. 
  • Follow steeping time instructions. Each tea has a specific steeping time that will result in the best cup possible. Following the steeping instructions can help bring out all of the tea’s deep and complex flavors.
  • Never over or under-steep your tea. Steeping your tea past the recommended time can make it bitter, and under-steeping can result in a pale cup or inferior flavor. If you want a stronger cup of tea, adjust the amount of tea you are using rather than changing how long you are steeping it.
