At a glance
Ban Tian Yao is a traditional named Wuyi rock oolong, written with several Chinese variants including 半天夭, 半天腰, 半天妖 and 半天鹞. Halfway to the Sky is one familiar translation. The story behind a name does not establish a packet’s growing site or grade.
| Detail | What to know |
|---|---|
| Chinese name | 半天夭 |
| Tea family | Oolong tea; Wuyi rock tea or yancha |
| Associated origin | Wuyishan, Fujian |
| Leaf form | Twisted strip-shaped Wuyi oolong leaves |
Taste and appearance
The earlier profile uses a layered fruity and roasted-nut direction, with almond, chestnut, pear, vanilla and brown-sugar comparisons. Those are sensory notes, not evidence of added nuts, flavouring or sugar. Roast and product conditions matter; the name does not require every cup to display every listed note.
The original liquor and infused-leaf pictures are withheld because identical images were assigned to other tea names. Their named identity could not be established; the files are preserved.
The cover above is the original dry-leaf illustration. Inherited images are not TeaPlain tasting samples or proof of age, origin, grade, authenticity or image rights clearance.
Grade characteristics
This preserves the earlier Chinese edition’s sensory comparison. It is not a complete verified current standard table and does not grade your packet. A tea-plant name, growing site, roast and product grade are different details. Decorative star rankings are omitted.
On a small screen, scroll the table sideways to compare the grades.
| Feature | Extra grade | Grade 1 |
|---|---|---|
| Dry-leaf shape | Substantial, tight, twisted and heavy | Naturally looser strips, weighty |
| Dry-leaf colour | Dark and lustrous, clear red points | Deep brown and lustrous |
| Liquor | Golden, clear and bright | Orange-yellow and bright |
| Aroma | Rich and lasting, changing floral/fruit notes | Roasted aroma with floral/fruit notes |
| Taste | Strong and full, returning sweetness, clear yanyun description | Sweet, mellow and full, slight bitterness/astringency, returning sweetness |
| Infused leaves | Not described in the original table | Not described in the original table |
The original infused-leaf cells were blank; descriptors have not been invented. The two sensory tiers are separate from the three undated price tiers. The different name spellings are not separate official grades.
Names and origin
The older account associates the original bush with the third Sanhua peak near Jiulongke and notes wider propagated plantings. Treat the cliff-site story as historical context rather than a current-packet origin certificate. Exact Yongle-period naming and a fixed four-famous ranking were not established in this review and are not presented as settled facts.
Everyday benefits
Brewed without added sugar, this is an ordinary tea drink that can be an alternative to sweetened drinks and contribute to fluid intake. It contains caffeine. These everyday properties do not establish that this named tea treats disease, lowers blood sugar or improves sleep. No TeaPlain clinical or brewing test is claimed here.
Who may enjoy this tea
You may enjoy it if you want to compare a named Wuyi oolong with a layered aroma description. Buy by traceable product and your own taste rather than a romantic translation or a claim that it outranks other named bushes.
When to take care
- Caffeine sensitivity or sleep problems: consider your total intake and timing if tea affects your sleep. A pale infusion is not a caffeine-free claim.
- Pregnancy, breastfeeding or medicines: ask a clinician or pharmacist about your actual product, caffeine intake and relevant medicine instructions.
- Iron supplements: follow the medicine’s instructions about separating tea from the dose. Do not use tea as treatment for anaemia.
These are product and individual considerations, not a blanket ban based on traditional “hot” or “cold” labels, age, sex or a constitution category.
How to brew
Original prose: porcelain gaiwan or clay pot
The original prose gives a porcelain gaiwan or clay pot, 1:15 tea-to-water ratio, 100°C / 212°F, preliminary wetting/rinse and a 20-second drinking infusion before decanting. It does not specify a measured dose. The example below makes the ratio explicit; its amounts are editorial arithmetic, not measurements inferred from the picture.
| Detail | Original prose with an explicit ratio example |
|---|---|
| Tea | 6 g loose Ban Tian Yao as an editorial example |
| Actual water | 90 mL / about 3.0 US fl oz, measured for the drinking infusion; 6 g at 1:15 |
| Vessel | Heat-safe porcelain gaiwan or suitable clay pot with room for leaves and actual water |
| Water temperature | 100°C / 212°F |
| First drinking infusion | 20 seconds, then decant completely; account for filling/pouring time |
| Preliminary wetting/rinse | Separate from the drinking infusion, not a validated disinfection step |
Use your actual packet’s complete directions first. These inherited methods and editorial examples are awaiting hands-on testing. The original seven-or-more-infusions statement is not a guarantee of equal-strength cups. Nominal teaware capacity is not actual added water after leaves displace space. Let the drink cool enough to sip; a steeping time is not a measured safe drinking temperature.
Read the original illustration separately
The original drawing gives 7 g in a gaiwan, 100°C, about five seconds for a discarded preliminary infusion and 5–10 seconds for the drinking infusion. It does not measure actual water or state capacity. These conditions remain separate from the prose’s 1:15/twenty-second example; neither claims a guaranteed number of identical cups.
For a larger mug, use a complete product method or the brew-without-a-gaiwan guide. Do not transfer twenty seconds from a high-leaf gaiwan ratio into a lower-leaf mug and call it the same preparation.
Adjust your cup
| What you notice | One change to try |
|---|---|
| Too strong, bitter or drying | Separate the liquid from the leaves; shorten contact time or use less tea next time |
| Weak or watery | Keep the measured water fixed and try a longer infusion before changing the leaf dose |
| Later infusions become stronger | Check whether liquid was left sitting with the leaves |
| Different from a flavour description | Compare the actual product and method; a description is not a promise for every cup |
Change one variable at a time. For a fuller sequence, see fix a disappointing first cup.
How to buy
Keep the Chinese name, maker, growing-area statement, harvest and roast together. Written variants can help identify the tea, but do not authenticate a cliff location or an exact ancient origin. Ask which actual product and grade a price describes.

China price reference
Undated figures retained from the Chinese edition, in Chinese yuan (CNY). No original brand, batch, harvest or quotation date was recorded. These are not verified current retail quotes, a market average or manufacturer-suggested retail prices.
| Chinese-edition tier | CNY per 500 g (one jin) | Equivalent CNY per 100 g |
|---|---|---|
| Extra grade | 6,500 | 1300 |
| Grade 1 | 1,520 | 304 |
| Grade 2 | 800 | 160 |
Per 100 g is an arithmetic conversion, not a quoted packet. Do not infer a missing sensory or price tier. Compare actual growing area, style, harvest, roast, weight and channel. A currency conversion does not make a UK or US retail offer comparable to a China historical figure.
How to store
Original storage method
For unopened small pouches, the source places the sealed pouches inside a tin. For bulk tea, it uses a foil pouch with excess air gently removed and the seal closed, followed by a lidded tin or porcelain container. Its vacuum-packing option is a packaging method, not an instruction to crush brittle leaves in a home vacuum sealer. Keep it cool, dry, away from smells, moisture and light.
The earlier tea-table or bookshelf example assumes those conditions; choose a cupboard if the shelf is sunny or near kitchen steam. The historical targets were below 25°C / 77°F, below 50% relative humidity, and a general 24–36-month shelf-life reference. These are legacy figures, not a freshly verified expiry or a remaining-life prediction for an opened packet. Follow the actual product label and seal/storage conditions.
In a UK or US kitchen
Keep daily use away from the hob or stove, dishwasher steam and spice containers, and reseal after each use. Roast style and packaging vary; do not carry a different oolong’s refrigerator advice into this packet without checking its label. No home re-roasting or ageing guarantee is prescribed. See storing an opened packet for everyday handling.
Origin, processing and history
The shared traditional Wuyi map shows leaf-working, repeated heating/rolling, drying, sorting and roast/packing operations. It is not unique proof of this tea’s origin or an explanation of every romantic name story. Exact fixed early-May picking and earliest-date assertions are not universal requirements for all packets.
Common questions
Is the spelling half-sky demon an ingredient or flavour rule?
The Chinese name has several written variants and translations. They are identification aids, not an ingredient declaration, a supernatural quality claim or a fixed flavour recipe. Keep the full tea name and producer information.
Does a high-leaf gaiwan method transfer directly to my mug?
No. Keep tea amount, actual water, temperature, timing and separation together. Use directions for the actual vessel and product rather than selecting one number from each method.
