Sun Moon Lake Black Tea: Taiwan’s Famous Black Tea from Nantou

Sun Moon Lake Black Tea is one of the most famous Taiwan black teas and an important part of Taiwan’s tea culture. This tea is grown around Sun Moon Lake in Yuchi Township, Nantou County, a region known for producing some of the most aromatic teas in Taiwan.

The unique climate around the lake — with frequent mountain mist, high humidity, and fertile soils — creates ideal conditions for tea cultivation. As a result, Sun Moon Lake tea is known for its smooth body, rich aroma, and complex flavor profile.

Today, Sun Moon Lake Black Tea from Taiwan is appreciated by tea lovers worldwide and is considered one of the finest examples of Taiwanese black tea.

Where Is Sun Moon Lake Black Tea Grown?

Sun Moon Lake Black Tea is produced around Sun Moon Lake in Yuchi Township, located in the mountainous region of Nantou County in central Taiwan.

Tea gardens in this area are typically situated at elevations of 700–1000 meters above sea level. The region benefits from:

• mild temperatures
• fertile mountain soils
• frequent fog and humidity
• stable growing conditions

These natural factors allow tea plants to grow slowly, which helps develop more complex aromatic compounds in the leaves.

Because of these conditions, Sun Moon Lake tea often has a richer aroma and smoother texture than many other black teas.

The History of Sun Moon Lake Tea

Black tea production in the Sun Moon Lake region began during the Japanese colonial period in the early 20th century.

At that time, Japanese tea specialists introduced Assam tea plants from India to Taiwan. These plants adapted well to the local climate and became the foundation of Taiwan’s black tea industry.

For many decades, Taiwanese black tea was exported to international markets, particularly to Europe.

Although black tea production declined during the late 20th century, the Sun Moon Lake region has experienced a strong revival in recent years. Today, the area once again produces some of the most respected Taiwan black teas.

Tea Cultivars Used for Sun Moon Lake Black Tea

Several tea cultivars are grown around Sun Moon Lake. Each cultivar contributes unique flavor characteristics to the final tea.

Ruby 18 (Hong Yu)

One of the most famous cultivars associated with Sun Moon Lake tea is Ruby 18 black tea, also known as Hong Yu.

This cultivar was developed by Taiwan’s Tea Research and Extension Station by crossing a Burmese tea plant with a local Taiwanese tea variety.

Ruby 18 tea is famous for its distinctive flavor profile, which often includes notes of:

• mint
• cinnamon
• honey
• ripe fruit

Because of its unique aroma, Ruby 18 has become one of the most recognizable Taiwanese black teas.

Taiwan Assam

Another cultivar grown in the region is Taiwan Assam, which descends from the original Assam plants introduced during the Japanese period.

Taiwan Assam teas are typically known for:

• full body
• malty sweetness
• smooth and rich flavor

Qing Xin Cultivar

Some farmers also produce Sun Moon Lake Black Tea using the Qing Xin cultivar, which is more commonly used for Taiwanese oolong tea.

When processed as black tea, Qing Xin leaves produce a lighter and more aromatic style of Sun Moon Lake tea.

Flavor Profile of Sun Moon Lake Black Tea

Sun Moon Lake Black Tea is valued for its complex aroma and smooth taste.

Depending on the cultivar and processing style, the tea may display different aromatic notes. However, many teas from this region share several common characteristics:

• smooth and rounded body
• natural sweetness
• rich aromatic complexity
• long and pleasant aftertaste

Some teas reveal subtle notes of mint and cinnamon, while others show hints of honey, dried fruit, or warm spices.

Unlike many strong black teas, Sun Moon Lake tea is usually low in bitterness and very smooth, making it enjoyable even without milk or sugar.

How Sun Moon Lake Black Tea Is Produced

The production of Sun Moon Lake Black Tea follows the traditional black tea processing method.

Harvesting

Tea leaves are typically harvested by hand. Only the young leaves and buds are selected to ensure the best flavor and aroma.

Withering

After harvesting, the leaves are spread out to wither, allowing moisture to evaporate and the leaves to soften.

Rolling

The leaves are rolled to break their cell structure and initiate the oxidation process.

Oxidation

Oxidation is the stage where the leaves develop their characteristic dark color and complex aroma.

Drying

Finally, the leaves are dried to stabilize their flavor and preserve the tea for storage.
