Taiwanese Orange Tea 臺灣橙茶 – A New Chapter in the World of Tea

The tea culture of East Asia is built upon a classification system that developed over many centuries. Tea from the plant Camellia sinensis is traditionally divided into six main categories: green tea, white tea, yellow tea, oolong, red tea (known as black tea in the West) and dark fermented teas called heicha. These categories are defined not by the color of the leaves but by the way the leaves are processed – the degree of oxidation, the method of heating, rolling and sometimes microbial fermentation.

In recent decades, however, an interesting development has emerged. Some tea producers, particularly in Taiwan, have begun experimenting with new processing techniques that combine elements from several traditional tea styles. One result of these experiments is the concept known as Orange Tea (橙茶), sometimes also called Brown Tea.

The name can be misleading. It does not refer to tea flavored with oranges nor to tea made from citrus peel. Instead, the name comes from the color of the infusion, which is typically bright orange to amber. What makes Orange Tea unique is its distinctive processing method.

Origins

Orange Tea is a relatively recent phenomenon. Its development is linked to modern experiments by Taiwanese tea producers, who are widely known for their creativity and innovation. Taiwan has long been a center of tea craftsmanship, and many famous tea styles originated there.

The idea behind Orange Tea was to create a tea that would combine several sensory qualities: the softness of white tea, the aromatic complexity of oolong and the fuller body of red tea. Through careful experimentation with withering, oxidation and drying, producers gradually developed a method capable of producing this new profile.

Orange Tea is defined primarily by its processing technique and its characteristic amber liquor.

Processing

The production of Orange Tea combines several traditional techniques. Harvesting is similar to that used for quality oolong or red teas, typically consisting of young leaves and buds. Because of the long processing time, the quality of the raw leaf is particularly important.

The most distinctive step is the extended withering stage. In green tea production withering is minimal, while in oolong production it usually lasts only several hours. In the case of Orange Tea, however, withering can last up to four days.

After withering, the leaves are rolled in a process similar to oolong production. Rolling breaks the cell walls of the leaves and allows oxygen to interact with the enzymes inside. This initiates oxidation.

In Orange Tea, oxidation falls somewhere between oolong and red tea. Compounds such as theaflavins, which give brightness and color to the liquor, and thearubigins, which contribute body and depth of flavor, are formed during this stage. When the desired oxidation level is reached, the leaves are heated and dried to stabilize the tea.

Aroma and flavor

Orange Tea is known for its layered and complex aroma. The infusion may reveal notes of orange blossom, honey, dried fruit, maple syrup or ripe apricot. These aromas are not added – they arise naturally from the transformation of the leaf during processing.

The liquor is usually smooth and rounded, with gentle sweetness and very little bitterness. Many tea drinkers describe the texture as soft and full, with a lingering aftertaste.

The liquor of Orange Tea is typically bright amber to orange in color.

Related styles

Orange Tea shares some similarities with several well-known tea styles. For example, the Taiwanese oolong Dongfang Meiren also produces a deep amber infusion and a honey-like aroma. However, its flavor develops largely due to the activity of leafhopper insects (Jacobiasca formosana), which trigger unique chemical reactions in the leaf.

Another comparable tea is Mi Xiang Hong Cha, the so-called honey black tea. Yet its production is closer to traditional red tea processing. Some heavily oxidized oolongs may also display similar amber tones. Orange Tea, however, stands somewhere between these styles.

Cultivars

Several tea cultivars may be suitable for producing Orange Tea. In Taiwan, examples include Qing Xin (青心), a traditional cultivar used for high-mountain oolong, Jin Xuan (金萱, TTES #12), known for its smooth and creamy character, and Hong Yu / Ruby 18 (紅玉), famous for aromatic red teas.

A new category?

Whether Orange Tea will become a recognized tea category remains uncertain. Historically, tea classifications evolved gradually over centuries. Oolong teas themselves developed through long experimentation, while dark teas such as pu-erh emerged partly from storage and trade practices.

For now, Orange Tea can best be understood as an experimental processing style. It may also function partly as a descriptive or marketing term, similar to the expression purple tea used for cultivars with elevated anthocyanin content.

The evolving world of tea

Orange Tea demonstrates that tea culture is not static. It is a living craft that continues to evolve as producers experiment with new techniques and flavor profiles. By blending traditional knowledge with modern curiosity, tea makers are discovering new possibilities hidden within the same humble leaf.

In a cup of Orange Tea, the softness of white tea, the complexity of oolong and the body of red tea come together – offering a glimpse into how tea culture may continue to develop in the future.
