Ruan zhi

China-Fujian

Ruan Zhi (Thai: เรือนชา

), also known as Qing Xin (Chinese: 青心 ), is a cultivar of Camellia sinensis var. sinensis, commonly known as the tea plant. Originating in Thailand, Ruan Zhi is highly regarded for its role in producing Oolong tea, a type of Chinese tea that is partially oxidized. This cultivar is particularly favored in the production of high-quality oolong teas in both Thailand and Taiwan, where it is often referred to as Taiwan Tea No. 17.

Characteristics

Ruan Zhi is known for its distinctive aroma and flavor profile, which can vary significantly depending on the level of oxidation and processing methods used. The tea leaves of the Ruan Zhi plant are typically dark green, with a somewhat glossy appearance and a slightly curled edge, characteristic of many oolong teas. When processed into tea, Ruan Zhi yields a light golden to amber-colored brew, with a floral and mildly sweet taste that is highly appreciated among tea connoisseurs.

Cultivation

The cultivation of Ruan Zhi requires specific environmental conditions, including high altitude, mild temperatures, and abundant mist. These conditions are commonly found in the mountainous regions of Thailand and Taiwan, making these areas ideal for producing high-quality Ruan Zhi tea. The tea plants are usually grown in small plots, where they can be carefully tended to ensure optimal growth and tea leaf quality.

Processing

The processing of Ruan Zhi tea involves several steps, including withering, rolling, partial oxidation, and drying. The level of oxidation is carefully controlled to achieve the desired flavor profile, ranging from green and floral to more robust and woody notes. This versatility makes Ruan Zhi a popular choice among tea producers looking to create unique oolong tea blends.

Cultural Significance

In both Thailand and Taiwan, Ruan Zhi tea holds a place of cultural importance. It is often served during special occasions and ceremonies, symbolizing hospitality and respect. The tea's unique flavor and aroma are celebrated, and its production is seen as an art form, passed down through generations of tea farmers and producers.
