Grown at 1,700 metres in Taiwan’s high mountains, this rare GABA Oolong comes from a Taiwan-certified organic tea farm. Cool temperatures and misty mountain air allow the leaves to develop exceptional depth and character. Naturally sweet and layered, it reveals ripe stone fruit, wildflowers, and honey, with a smooth, lingering finish.

If you enjoy expressive natural wines, you may find a familiar character here: vibrant, complex, and beautifully shaped by its terroir.

A refined Taiwanese GABA Oolong for slowing down and savoring the moment.

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.

Hot & Cold Brew

  • Hot Brew
    Loose leaf:8 g tea + 400 ml water, 95–100°C,1 minute
    Tea bag:    1 tea bag + 300 ml water, 95–100°C,2–3 minutes

  • Cold Brew
    Loose Leaf: 5 g tea + 500 ml water
    Tea Bag: 3 g tea bag + 300 ml water 
  1. Steep at room temperature for 1 hour.

The Tea Farm — Where Our Tea Begins

In the misty, high-altitude tea gardens of Ren’ai Township, Taiwan, our partner farmer cultivates tea using certified organic farming practices, in deep harmony with the land and seasons.

Before dedicating herself to natural farming, she traveled the world as an international flight attendant and certified wine-tasting lecturer. Her experience with wine gave her a refined appreciation for the land, the unique interplay of soil, climate, and elevation that shapes exceptional High Mountain Oolong.

Today, she avoids synthetic pesticides, chemical fertilizers, and herbicides. Her tea gardens are certified for organic cultivation in Taiwan by the National Chung Hsing University Agricultural Products Certification Center (NCHU), reflecting her commitment to pure mountain terroir and sustainable farming.

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 Oolong tea is specially processed to naturally increase its GABA (Gamma-Aminobutyric Acid) content. The tea leaves undergo controlled anaerobic fermentation, creating a smooth, mellow profile with gentle sweetness and reduced astringency. This distinctive Taiwanese tea combines traditional oolong craftsmanship with modern processing techniques, making GABA Oolong known for its unique character and naturally occurring GABA.

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.
