Cangui Guyun: Five Whole-Leaf Oolong Sachets
- Cangui Guyun is TEAGRAPHY's sachet range: five whole-leaf, longan-charcoal-roasted oolongs, each boxed as five individually sealed sachets.
- Each name is glossed as a 'triple' element: Xin (Metal) is Jin Xuan, Sen (Wood) is Songboling Changqing, Miao (Water) is Qingxin, Yan (Fire) is Red Oolong and Yao (Earth) is Cui Yu.
- Sachets hold 6 g or 7 g of loose whole leaf with no filter bag, nitrogen flushed to stay fresh until opened.
- One sachet makes one 300 ml pot: water at 95-100°C, steeped for 6-7 minutes.
- The Cangui Guyun Gift Box pairs any two of the five boxes, so the recipient gets ten sachets and two different roasts.
Cangui Guyun is TEAGRAPHY's collection of five charcoal-roasted Taiwanese oolongs, each packed as five individually sealed whole-leaf sachets. Each sachet holds exactly enough leaf for one 300 ml pot, so you get the depth of loose-leaf oolong without weighing anything.
The range was designed for people who love whole-leaf tea but brew in offices, hotel rooms and busy kitchens. This guide explains what is inside each box, how the five teas differ and how to brew a sachet so it tastes the way the roaster intended.
What is Cangui Guyun?
Cangui Guyun, also written Cang Hui Gu Yun, is a sachet line from TEAGRAPHY, the brand of Longhui Tea House, which has grown tea at Songboling in Nantou, Taiwan, since the 1960s. Every tea in the range is hand roasted over longan wood charcoal, with no more than 6 kg of leaf to a basket and the roasting master keeping watch for 3 to 10 hours.
- Format: 5 sachets per box, 6 g or 7 g each, no filter bag.
- Freshness: each sachet is nitrogen flushed and sealed at source.
- Leaf: Taiwanese whole leaf tea, grown and packed at source.
- Testing: each single box page states that the tea passed an SGS 481-item pesticide residue test.
If you are comparing formats, our guide to loose leaf vs tea bags explains why whole leaf still matters for a cup like this.
The five teas, named for five elements
Each box carries a one-character name that the official gift box page glosses as a "triple" element. The name hints at the mood of the tea; the variety tells you what is in the cup.
Xin (Metal): Jin Xuan oolong
Natural milky notes and sweet corn, soft and fresh on the palate. The product page notes that the milk-candy note grows clearer as the tea cools slightly and peaks while it is still warm. Explore Cangui Guyun Xin (Metal) or read more in Jin Xuan (Milk Oolong) Explained.
Sen (Wood): Songboling Changqing tea
A bright, lifted fragrance with a hint of gardenia and a clear, pale gold liquor. After longan-charcoal roasting, a clean, lightly sweet fruit note joins the floral aroma. See Cangui Guyun Sen (Wood).
Miao (Water): Qingxin oolong
Orchard fruit and osmanthus with a golden, translucent liquor. A gentle, light astringency gives way to a long, salivating sweetness. See Cangui Guyun Miao (Water).
Yan (Fire): red oolong
Ripe fruit with a sweet finish. Red oolong combines oolong and black tea processing, so the orange-red liquor has the colour and aroma of black tea but the mellow sweetness of oolong. See Cangui Guyun Yan (Fire) and our red oolong guide.
Yao (Earth): Cui Yu oolong
A layered floral profile, described on the product page with notes of betel palm blossom, magnolia and wild ginger flower. See Cangui Guyun Yao (Earth).
How to choose between the five
Start with the aroma you already enjoy in other drinks, then work outward.
- You like creamy, gentle cups: start with Xin.
- You like floral white wine or jasmine: try Sen or Yao.
- You like stone fruit and honey: choose Miao.
- You drink black tea or want more depth: choose Yan.
Not sure? Brew two side by side in the same week. Because every sachet is pre-portioned, the comparison is fair and simple.
How to brew a Cangui Guyun sachet
The official brewing guide is the same for all five teas:
- Heat water to 95-100°C. Hot water helps the rolled leaf open.
- Empty one sachet into a 300 ml pot or roomy infuser. The leaf is loose, so give it space.
- Steep for 6-7 minutes. TEAGRAPHY's FAQ warns that most people stop too early; the honey note and throat-feel arrive at the end of the window.
- Strain completely and smell the empty cup. The fragrance left in the bottom of the cup carries the sweetness of longan charcoal.
For small-teapot methods and re-steeping, see How to Brew Taiwanese Oolong. For a cooler cup, every Cangui Guyun page carries a cold-brew tag, and our guide to why charcoal-roasted tea keeps its aroma explains the roast behind that stability.
Where sachets fit best
TEAGRAPHY's FAQ puts it simply: choose the 50 g tins if you brew often at home, and the sachets for travelling, the office or a gift. A sealed sachet slips into a bag, needs no scale and still gives you whole leaf in the pot.
- Office: one sachet, one mug-sized pot, one timer.
- Travel: sealed portions stay fresh until opened.
- Hosting: open two different boxes and let guests compare.
The Cangui Guyun Gift Box
The Cangui Guyun Gift Box holds any two of the five boxes, so you can repeat a favourite or pair contrasting teas such as Xin and Yan. The gift box page lists a Highest Gold Award from the World Green Tea Association of Japan 2021 tea evaluation and an SGS 488-item pesticide residue test.
For more ideas on matching a tea to the person, read our Taiwan tea gift guide.
Storing opened sachets
Unopened sachets stay sealed until you open them. Once opened, brew the whole sachet, or reseal and store the leaf away from air, light, damp and strong smells.
Cangui Guyun makes Taiwanese oolong easy to carry without reducing it to dust in a bag. Pick the element that suits your mood, give it hot water and time, and let the charcoal-roasted finish show itself.
