Rooted in the rolling foothills of Mingjian, Taiwan, this GABA Oolong is gently fermented to develop a naturally fruity, mellow character with remarkably low bitterness. Notes of dried fruit, ripe plum, and caramel lead to a soft, velvety finish.

If you enjoy easy-drinking natural wines, you may find a familiar character here: fruity, softly fermented, and beautifully rounded.

A comforting choice for early evening or a mindful moment to slow down and reconnect with the day.

Multiple Infusions - Worth Every Leaf

Taiwanese Oolong is made to be brewed more than once. Its tightly rolled leaves gradually unfurl with each infusion, allowing the aroma and flavor to evolve from one brew to the next.

Traditional Teapot Brewing
For a more concentrated style, use 6 g of tea with 100 ml of hot water. The same leaves can be infused at least 5 times, with each infusion revealing a different character.

Larger Pot Brewing
For a larger pot, use around 8 g of tea with 400 ml of hot water. The same leaves can typically be brewed up to 3 times.

The second infusion is often especially expressive, as the leaves continue to open. Later infusions gradually become lighter and more delicate.

There is no single “right” way to brew Oolong. Adjust the tea, water, and steeping time to find your preferred flavor.

The Tea Farm — Where Our Tea Begins

Rooted in the rolling foothills of Mingjian Township, Taiwan (300–400m), this distinctive GABA Oolong reflects the character of its land and the craftsmanship of our local tea farmer. Her background in wine and deep connection to the land bring a sommelier’s appreciation of **terroir, elevation, and seasonal character** to every batch.

Made from whole-leaf Qingxin Oolong (青心烏龍), the leaves undergo controlled fermentation in an oxygen-free environment. This specialized process encourages the natural development of GABA (gamma-aminobutyric acid), transforming the tea into a naturally smooth, fruity cup with remarkably low bitterness.

What Is Oolong Tea ?

Taiwanese Oolong tea is a partially oxidized tea made from the Camellia sinensis plant. Its oxidation level, cultivar, altitude, and craftsmanship shape its aroma and flavor. Taiwanese high-mountain Oolong is especially valued for its floral fragrance, smooth texture, natural sweetness, and lingering finish. Unlike fully oxidized black tea or minimally oxidized green tea, Oolong sits between the two in processing.

What Is GABA Tea?

GABA tea is specially processed to naturally increase its GABA (Gamma-Aminobutyric Acid) content. GABA is a naturally occurring neurotransmitter that helps regulate communication between nerve cells in the brain and is involved in calming and balancing brain activity.

During production, the tea leaves undergo a controlled oxygen-free (anaerobic) process that encourages GABA to naturally accumulate.

GABA tea is commonly defined as containing at least 150 mg of GABA per 100 g of dry tea leaves. All of our GABA teas are laboratory tested and contain more than 150 mg of GABA per 100 g of dry tea leaves.

GABA Oolong, especially well known in Taiwan, combines this modern processing method with traditional oolong craftsmanship to create a smooth, mellow tea with gentle sweetness and reduced astringency.

Tested for Purity

From Tea Leaf to Packaging

Tea quality goes beyond flavor. All our tea undergoes independent third-party laboratory testing for pesticide residues and heavy metals, helping verify purity, food safety, and compliance with applicable Swiss and European standards. Our tea is processed in a facility whose food-safety production system is certified to FSSC 22000, with food-safety practices aligned with ISO 22000 and HACCP principles. Pesticide residues are also checked on a batch-by-batch basis before production. Quality control extends from the tea leaf to the packaging materials that come into direct contact with the tea, providing an additional layer of assurance for purity, safety, traceability, and consistent quality.
