What Is Oolong Tea? Health Benefits, Characteristics, Prep

What is oolong tea?

Oolong Tea has a long history in China and Taiwan. It grows well in the high, mountainous regions of China. There are many legends regarding the origins of Oolong, which demonstrates its central importance to Chinese culture. Nowadays, Oolong grows well in China, Taiwan, New Zealand, and Sri Lanka. Each region's Oolong will have an incredibly unique look and flavor.

Oolong belongs to its own category of tea, it is neither black tea nor green tea, but instead falls somewhere in between. When Black Tea is processed, it is very oxidized, giving it a signature dark hue. Green tea, on the other hand, is not given much time to oxidize. Oolong's oxidation time falls somewhere in the middle.

Oolong Tea has a unique shape. Oolong means "black dragon" in Chinese. Traditionally, the tea maker twists Oolong Tea into tight balls. These Oolong balls have a unique look, but the shape also affects the flavor and aroma of the tea.

The rolling process entirely dictates the tea's final flavor. The method of creating oolong tea brings out fantastic health benefits, including weight loss in the delicious brew.

How is oolong tea made?

When first picked, tea leaves are quite fragile. During the withering process, freshly-picked leaves are laid out in the sun to dry. As they dry, the tea leaves become softer and more flexible. This way, they are durable enough for the rolling process.
The tea leaves must be cooled off once they’ve spent time in the sun. Cooling the tea leaves causes them to shrink in size, making them ready to roll.
Light Rolling
Rolling the tea leaves breaks down the tea's cell walls, exposing more of the surface area to oxygen. The leaves then begin to oxidize. The degree to which the tea oxidizes dictates the color, aroma, and flavor of the tea.
As mentioned before, the oxidation process determines what type of tea your leaves will become. Oolong Tea can oxidize anywhere from 8-80%. The longer the tea oxidizes, the deeper and richer the Oolong Tea will become
Once the tea leaves have oxidized, it’s time to apply heat. Roasting the tea leaves adds unique flavors to the tea leaves.
Final Rolling
This final rolling process is what gives Oolong Tea its characteristic shape and finalizes the flavor of the tea.
Before the Oolong Tea can be stored or sold, it must be completely dried out. If moisture remains in the tea, it can cause the leaves to rot and spoil.
Hand Sorting
Finally, the tea leaves are sorted based on shape, size, and color. Similar leaves are placed together and sold based on the flavor profile they will yield.

How to steep oolong

Oolong Tea is simple to make. Place one teaspoon of Oolong Tea into one of our Natural Paper Drawstring Tea Bags or your preferred Full Leaf Signature Leaf Infuser.

Steep the tea in boiling, filtered water. Try to use cold water that has not been boiled before. If you are steeping Oolong Tea in the shape of a ball, instead of loose-leaf, it will infuse more quickly. If it is loose-leaf, steep the tea for 5-7 minutes.

The Oolong Tea leaves will open up and release their flavor as the tea steeps. Once this process is over, you can remove the leaves from the tea, and enjoy!
