WULONG TEA is one of the most diverse and technologically sophisticated categories of tea, occupying a unique position between green and red (black) tea. Through partial oxidation and complex processing techniques, wulong tea develops an extraordinary range of aromas and flavors while preserving a rich concentration of naturally occurring polyphenols, amino acids, vitamins, minerals, and aromatic compounds.
The degree of oxidation in wulong tea can vary significantly, from lightly oxidized floral styles to heavily roasted and deeply oxidized examples. This diversity allows wulong tea to combine the freshness and vitality often associated with green tea with the depth and richness characteristic of red (black) tea. It is believed that regular consumption of wulong tea may support cardiovascular health, contribute to healthy metabolism, assist the body's natural antioxidant defenses, improve mental alertness and concentration, and help reduce physical and emotional fatigue. Traditionally, wulong tea has also been appreciated for its ability to promote digestion, create a feeling of balance and clarity, and support a calm yet focused state of mind.

SEED-GROWN TEA PLANT
This tea refers to a Qunzi Zhong, a "seed-grown tea plant". Unlike cloned or asexually propagated cultivars, which are created by cuttings or grafting from a single "mother" plant, Qunzi Zhong tea trees are grown from seeds. This results in a genetically diverse population of plants. Each seed-grown tea tree is unique, with slightly different characteristics. This genetic variety helps improve the resilience of the tea garden, making it more resistant to pests, diseases, and environmental stress. Seed-grown trees usually develop stronger and deeper roots than cloned plants, allowing them to draw nutrients and minerals from deeper soil layers, often giving the tea a more complex and rich flavor profile. Qunzi Zhong represents the traditional way of tea cultivation. Because of the genetic diversity, teas made from Qunzi Zhong plants tend to offer more layered and nuanced flavors, reflecting a richer expression of the local terroir (soil, climate, and environment).
PESTICIDE-FREE GARDENING
Pesticide-free gardening refers to a cultivation method in which no synthetic chemical pesticides are used at any stage of plant growth. Instead, this approach relies on biodiversity, ecological balance, and cultural practices to manage pests and diseases. Unlike conventional farming, which often depends on chemical intervention to control infestations, pesticide-free gardening emphasizes prevention through healthy soil, companion planting, and natural predators. This method fosters a more resilient and adaptive garden ecosystem. Without chemical inputs, beneficial insects such as ladybugs, lacewings, and native bees thrive, contributing to pollination and pest control. Untouched by harsh agents, the soil remains alive with microbial activity, supporting deeper root systems and more vigorous plant development. Over time, this results in produce with purer, more expressive flavors, reflecting the health of the environment and the grower's intention.

Learn more about TEA BREWING METHODS
Tea absorbs surrounding aromas and moisture. This type of tea oxidizes when it comes into contact with oxygen and loses its properties, including taste and aroma. Store it in a dry and cool place in airtight packaging. Avoid direct exposure to the sun and high temperatures.
BEST BEFORE: 2 years since production date!
*Suitable for long-term aging. Under proper storage conditions, the tea may gradually develop increased depth, smoothness, and complexity.

ABOUT
RARE JADE GABA is a high-grade Taiwanese GABA Wulong produced in Nantou from carefully selected, highest-quality tea material. Particular attention is given to the quality and condition of the fresh leaves, providing a refined foundation for GABA processing while preserving the natural aromatic complexity of Taiwanese wulong. The result combines the distinctive character of GABA tea with the clarity, elegance, and aromatic depth expected from premium-grade material.
The production follows a wulong-style approach, including withering, partial oxidation, and drying, combined with controlled anaerobic processing. During the oxygen-free stages, naturally occurring glutamic acid in the leaves is converted into gamma-aminobutyric acid (GABA), resulting in a significantly increased GABA concentration. Careful control of this process is essential not only for the chemical composition of the tea but also for maintaining a clean, balanced, and expressive sensory profile.
RARE JADE GABA represents a more refined expression of Taiwanese GABA Wulong, where specialized processing is supported by exceptional raw material and skilled craftsmanship. It is distinguished by its rich and complex aroma, pronounced natural sweetness, smooth texture, balanced structure, and long-lasting aftertaste. Rather than being defined by GABA processing alone, this tea combines a high GABA concentration with the taste and aromatic qualities of a genuinely high-level Taiwanese wulong.

TERROIR
The area lies at low to mid elevations and is characterized by a humid subtropical climate with abundant rainfall, warm temperatures, and frequent cloud cover. These conditions support steady plant growth and allow the leaves to develop both aromatic intensity and structural balance.
The terrain consists of gently rolling hills with well-drained soils rich in organic matter and minerals. These soils provide a stable nutrient base, supporting the development of the Hong Yu cultivar without excessive vigor. The result is a dense and resilient leaf material, well suited for both oxidation and the subsequent GABA processing. Microclimate plays a defining role, with diffused sunlight, stable humidity, and consistent air circulation regulating plant metabolism. Compared to higher mountain regions, the leaves develop more quickly, contributing to a fuller body and more pronounced structure. The balance between amino acids and polyphenols supports both sweetness and depth in the final tea.
Another important aspect is the interaction between terroir and processing. The composition of leaves grown in these regions allows them to respond effectively to anaerobic treatment, facilitating the development of GABA while maintaining aromatic clarity. This integration ensures that the final tea expresses both the regional character of Taiwan and the unique qualities introduced through specialized processing.
ORGANOLEPTICS
The dry leaf is semi-rolled with a slightly twisted structure, showing dark brown to reddish tones, reflecting both oxidation and GABA processing. The aroma of the dry leaves is warm and expressive, with notes of ripe fruit, honey, light spice, and a subtle herbal nuance characteristic of the Hong Yu cultivar. In a preheated teapot, the leaves begin to open from the first infusion, releasing a rich aromatic profile where fruity sweetness is supported by gentle spicy and slightly minty undertones. As the infusion develops, the aroma becomes more integrated, combining dried fruit notes with a smooth, rounded depth.
The aroma of the liquor is full and harmonious, with a balanced combination of fruit, honey, and light spice. The taste is smooth and mellow, with a medium body and a soft, slightly viscous texture. A pronounced natural sweetness forms the core of the profile, supported by notes of ripe fruit, light herbal tones, and a mild, well-integrated astringency that adds structure. The GABA processing is reflected in the rounded and calming character of the tea. The aftertaste is long and gentle, with a returning sweetness and a soft, slightly cooling finish. In the empty cup after drinking, a delicate fruity and lightly sweet aroma remains, leaving a calm and refined final impression.
