At a glance
Guzhu Zisun, also called Changxing Zisun or Purple Bamboo Shoot, is a Zhejiang green tea. The older name explanation refers to a faint purple cast in fresh young material and leaves resembling bamboo-shoot husks. It does not mean the finished drink contains bamboo shoots or must be purple.
| Detail | What to know |
|---|---|
| Chinese name | 长兴紫笋（顾渚紫笋、湖州紫笋茶） |
| Tea family | Green tea |
| Associated origin | Guzhu Mountain area, Shuikou, Changxing, Huzhou, Zhejiang |
| Leaf form | Tender bud-and-leaf material, tightly worked, sometimes slightly flattened |
Taste and appearance
The inherited comparison describes tight, straight, tender and even material, white hairs, intact buds and leaves, green dry colour and bright pale-green liquor. The fragrance is clean, high or lasting, and the cup fresh, brisk, mellow or full according to tier. The older account describes leaves opening into an orchid-like form; that is a visual comparison, not an added orchid ingredient.
The cover is the original dry-leaf illustration. These images are not TeaPlain tasting samples or proof of origin, grade, age, 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. Plant material, growing area, processing and grade are separate details. Decorative star rankings are omitted.
On a small screen, scroll the table sideways to compare the grades.
| Feature | Extra grade | Grade 1 | Grade 2 |
|---|---|---|---|
| Dry-leaf shape | Tight, straight, fine and tender, white hairs visible, intact and even | Tight, straight, slightly flattened and even | Straight, slightly flattened and even |
| Dry-leaf colour | Green | Lustrous green | Green, fairly lustrous |
| Liquor | Pale green and bright | Green and bright | Green, fairly bright |
| Aroma | Lasting clean fragrance | High, clean fragrance | Fairly high fragrance |
| Taste | Fresh and brisk | Fresh and mellow | Full and mellow |
| Infused leaves | Tender and even, green and bright | Tender and even, green and bright | Green and bright |
The original sensory account is kept. A purple naming story does not turn these green-colour cells into a defect or certify one universal picking.
Names and origin
The original places the tea around Guzhu Mountain in Shuikou, Changxing, Huzhou. An identified contemporary maker connects its product with a tribute-tea tradition and describes fresh material with an occasional purple blush and a modern loose-leaf making method. Ancient tribute-tea history does not prove an unchanged present-day process, one universal bud-only picking or purple liquor. The older literal boiling-water phrase is not silently made into a replacement for the specific retained recipes.
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
It may suit someone exploring a fresh, clean-fragrant green tea and Changxing’s tribute-tea heritage. A historical imperial association is cultural context rather than a universal ranking or a promise of an unchanged ancient recipe.
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: heat-safe glass
The earlier method uses a heat-safe glass, 1:50 tea-to-water ratio and 85–90°C / 185–194°F water. It says to refill when about one-third of the liquid remains, and describes roughly three infusions/refills. It supplies no first steeping time. Keep the retained illustration’s method separate below.
| Detail | Original prose with an explicit ratio example |
|---|---|
| Tea | 3 g Guzhu Zisun as an editorial arithmetic example |
| Actual water | 150 mL / about 5.1 US fl oz, measured water; 3 g at 1:50 |
| Vessel | Heat-safe glass with room for the leaves and actual water |
| Water temperature | 85–90°C / 185–194°F |
| First drinking infusion | No first steeping time recorded in the prose; follow a complete packet method |
| Refill | At about one-third liquid remaining; refilling is different from a full fresh measured batch |
These inherited directions and explicit ratio examples are awaiting hands-on testing. Nominal vessel capacity and a drawn fill fraction do not measure actual water. Three repeat cups is not a guarantee of equal strength. If leaves remain in the glass, extraction continues; transfer or strain if the cup becomes too strong. Let the drink cool enough to sip.
Read the original illustration separately
The original graphic gives 3 g, 80–85°C / 176–185°F and 1:50, which arithmetically implies 150 mL actual water. It names a glass or porcelain gaiwan and three claimed infusions, but no first steeping time or vessel capacity. This specific graphic and the prose’s 85–90°C range remain separate from the introduction’s unspecific boiling-water phrase. Use a complete packet method.
For ordinary teaware options, see brew without a gaiwan. Keep each complete method together instead of selecting temperature, dose and time from different preparations.
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
Check the actual grower or maker, Changxing locality, harvest and picking. A faint purple fresh-leaf description does not require every dried leaf or cup to show the same colour. The original has three sensory tiers but only two prices; no missing price or process image is invented.
See buy your first Chinese tea for packet comparisons.
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 | 600 | 120 |
| Grade 1 | 450 | 90 |
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.
Only Extra grade and Grade 1 prices were supplied. No Grade 2 price is invented from the three-column sensory table.
How to store
Original storage method
The original method places green tea in a closed foil pouch, gently removes excess air, then puts the pouch inside a lidded iron or tin container upright for refrigerated storage, protected from light, moisture and smells. Check that a paper pouch is actually lined and moisture resistant; plain paper alone is not an airtight moisture barrier.
Its general reference was 12 months, with storage below 10°C / 50°F and below 50% relative humidity. It also described a cool, shaded room-temperature option for tea expected to be finished within two months. These are inherited conditions, not a verified expiry or a remaining-life prediction for an opened packet. Follow the actual maker’s label, package and specified conditions first.
In a UK or US kitchen
If following a product’s cold-storage directions, keep the pack sealed against fridge moisture and food smells, and let it warm while still sealed before opening. Keep a working portion away from the hob or stove, dishwasher steam, sunlight and spices; reseal after use. Do not apply a refrigerator recipe to another tea automatically. See storing an opened packet for handling.
The original green-tea handling note keeps a separate one-to-two-week working portion to avoid repeatedly warming and opening the bulk cold pack. Portion in dry conditions and seal each pack.
Origin, processing and history
No process illustration was supplied with this original article. The old name and appearance account is preserved without inventing a missing diagram. An identified modern maker describes spreading, hand heating and subsequent drying for its own loose-leaf product; that does not establish an identical sequence for all products or an unchanged method since tribute-tea times.
Common questions
Should Purple Bamboo Shoot tea make a purple drink?
The name refers to the older appearance and naming account, especially fresh young leaf, not a required purple liquor. This entry concerns green tea. Check actual origin and product description rather than using purple colour as an authenticity test or assuming bamboo ingredients.
Can I move one number from this recipe into a different vessel?
Keep leaf form, measured dose and actual water, temperature, timing and separation together. Nominal capacity or a fill fraction is not a measured ratio.
