Every tasting note on this site follows the same method. Same vessel. Same water treatment. Same evaluation sequence. Same ten dimensions scored on the same scale. The reason is simple: if the method changes between sessions, you can’t compare the results. And comparison — across teas, across sessions, across weeks of developing palate — is where learning happens.
This article documents the complete protocol so you can reproduce it. Brew the same tea I’ve documented with the same parameters, score it yourself, and compare your experience directly against mine. Where our scores diverge, that divergence is the conversation. It means your palate reads something differently than mine, and that difference is data — about the tea, about your sensory profile, about what you’re learning to detect.
The Steep Atlas Tasting Protocol is not the only way to evaluate tea. Chinese competition judging uses different criteria. Japanese tasting emphasizes different dimensions. Wine evaluation frameworks like the UC Davis scorecard or the WSET systematic approach informed parts of this design but diverge in others. This protocol is designed for one purpose: documenting gongfu tea sessions with enough precision to make every session comparable over time.
The Controlled Setup
Before tasting, control the variables that aren’t the tea.
Vessel: 100ml white porcelain gaiwan (盖碗). Every session. White porcelain is neutral — it doesn’t absorb flavor, doesn’t add character, doesn’t flatter or conceal. What you taste is the tea and nothing else. If you use a clay pot or a Korean celadon gaewan for your daily practice, that’s fine — but evaluation sessions use porcelain. It’s the control.
Water: Filtered. The same filter, the same source, every session. Water chemistry changes tea flavor dramatically — the same leaf brewed in different cities tastes different because the mineral profiles differ. Controlling water eliminates a variable. If you’re serious about it, measure your water’s TDS (total dissolved solids) with a $10-15 meter. Target 50-150 ppm.
Leaf amount: Measured by weight, not volume. 6-7g for most teas. 7-8g for shou pu-erh and hei cha. 4-5g for green and white tea. A digital scale ($15-25) is not optional for evaluation. Dry tea leaves vary enormously in density — 7g of tightly compressed pu-erh looks like a small chip. 7g of fluffy white tea looks like a handful. Eyeballing consistently underdoses, which changes every dimension of the evaluation.
Water temperature: Matched to tea type. 70-80°C for green and white. 85-95°C for light oolong. 95-100°C for pu-erh, yan cha, and dark tea. Use a variable-temperature kettle or a thermometer. Temperature is the single largest variable affecting extraction after the tea itself.
Environment: Neutral smell. No perfume, no incense, no cooking aromas. Your nose adapts to persistent smells and stops detecting them, but they still interfere with subtle tea aromatics. A clean, well-ventilated space. Morning sessions tend to produce sharper tasting because the palate hasn’t been fatigued by a day of eating and drinking.
Palate state: No food for at least 30 minutes before tasting. No coffee. No strong flavors that coat the mouth. Water to rinse between teas if comparing more than one.
The Evaluation Sequence
Follow this order every session. The sequence is designed to capture information in the order it becomes available — dry leaf first (before water touches it), then wet aroma, then liquid, then aftertaste, then the body’s response.
1. Dry Leaf
Before any water, examine and smell the dry leaves.
Visual: Leaf size, shape, color, uniformity. Compressed or loose. Presence of buds (silvery tips), stems, or broken leaf. For pu-erh cakes: examine the surface and break a piece from the edge — the interior and exterior may differ in compression and aging exposure.
Aroma: Hold the dry leaves close to your nose. Inhale slowly. What do you detect? Floral, fruity, woody, earthy, smoky, nutty, marine, vegetal? The dry leaf aroma is the first data point and often reveals character that the brewed liquor doesn’t emphasize. A pu-erh with camphor in the dry leaf will carry camphor through the session even when other flavors dominate the cup. A dancong whose dry leaf smells like gardenias will deliver that gardenia in the first three steeps.
2. The Rinse and Wet Leaf Aroma
Pour boiling water over the leaves. Wait 2-3 seconds. Pour off and discard the liquid.
Now smell the wet leaves in the gaiwan with the lid slightly displaced. This is the single most information-dense moment in the entire session. The heat has volatilized compounds that were locked in the dry leaf. What you smell now — for 10-15 seconds before the aromatics fade — tells you what the tea is about to do. Earthy and dark? Expect body and depth. Floral and bright? Expect aromatics and delicacy. Camphor and herbs? You’re holding something aged.
Smell the underside of the gaiwan lid separately. Different compounds adhere to the lid than rise from the leaves — the lid aroma is often sweeter and more concentrated than the open-leaf aroma.
3. The Session: Steep by Steep
This is the core. Each steep is a data point.
Pour water at the correct temperature. Start timing. Pour off into the fairness pitcher when the time is up. Pour from the pitcher into the cup. Evaluate.
Steep 1-2 (the opening): Light. Aromatic. Surface compounds extract first. Don’t form a judgment here — this is the overture. Note the first impressions but hold them loosely.
Steep 3-5 (the core): This is where the tea declares itself. Body peaks. Flavor complexity peaks. Huigan arrives or doesn’t. Cha qi emerges or doesn’t. If you’re evaluating quality, these are the steeps that matter most. Spend the most attention here.
Steep 6-8 (the plateau): Quality tea holds. Mediocre tea drops. Track whether the flavor sustains, shifts, or collapses. Sweetness often increases in this range as bitter compounds are exhausted.
Steep 9+ (the fade): The tea gives its last. Flavors simplify. Sometimes a clean mineral or sweet character emerges that the earlier steeps’ complexity masked. Don’t stop too early — late steeps have taught me things that the peak steeps concealed.
For each steep, note: color of the liquor (hold the cup against a white background), primary flavor, secondary flavors, mouthfeel, and any aftertaste or huigan.
4. Flavor Profile: Front, Mid, Finish
After the session, synthesize the flavor into three phases:
Front: What hits first. The initial impression in the first 2-3 seconds after the liquor enters your mouth. Often the brightest, most volatile compounds — floral notes, citrus, smoke.
Mid: What develops. The 3-10 second window as the liquor moves across the palate. Body, sweetness, bitterness, mineral character, complexity. This is where most of the interesting information lives.
Finish: What lingers. After you swallow, what stays? How long? Does the flavor change (bitterness converting to sweetness = huigan)? Does the throat resonate (hou yun, 喉韻)? A long, evolving finish is one of the most reliable markers of quality in tea, just as it is in wine.
5. Mouthfeel and Huigan
Mouthfeel and returning sweetness get their own evaluation because they’re physical sensations distinct from flavor.
Mouthfeel: How does the liquor feel in the mouth? Thin or thick? Coating or clean? Silky, velvety, oily, astringent, drying? The vocabulary overlaps with wine — a full-bodied shou with a velvety coating mouthfeel is the tea equivalent of a dense, plush Pomerol. A lean, structured young sheng with gripping astringency is the Barolo.
Huigan (回甘, returning sweetness): After you swallow, does sweetness return? How quickly? How intensely? How long does it persist? Huigan is the defining quality marker in pu-erh — the speed and intensity of the bitterness-to-sweetness conversion tells you more about the raw material than any other indicator. The strongest huigan I’ve experienced persisted for over 20 minutes and transformed plain water tasted afterward into something detectably sweet. What Is Huigan? The Returning Sweetness Explained covers this in full.
6. Qi and Body Sensations
Cha qi (茶气) is the most debated concept in tea. I score it conservatively.
Qi refers to body sensations beyond flavor — warmth spreading through the chest, tingling in the limbs, a calming wave, alertness without jitteriness, or in extreme cases cha zui (茶醉, tea drunkenness: lightheadedness, warmth, an altered state that resembles mild intoxication). I’ve experienced cha zui once, from a 38-year aged sheng brewed on an empty stomach. It was unmistakable.
Not every tea produces detectable qi. Not everyone detects it the same way. The mechanism is debated — L-theanine, caffeine, GABA, polysaccharides, and placebo have all been proposed. I don’t claim to know what causes it. I claim to know when I feel it. When I do, I score it. When I don’t, I score it low. A cha qi score of 7+ on this site means I experienced clear, unmistakable body sensation beyond normal caffeine stimulation.
The Ten Dimensions
Every tasting note scores the tea across ten dimensions on a 1-10 scale. These scores generate a radar chart on the article page — a visual fingerprint of the tea’s profile that lets you compare shapes across teas at a glance.
| Dimension | Code | What It Measures | Scoring Anchor |
|---|---|---|---|
| Aroma | AR | Combined dry and wet leaf aromatic intensity and complexity | 7+ = complex and layered, multiple distinct notes |
| Astringency | AS | Drying, gripping sensation on the palate | Not inherently negative — some teas need it. 7+ = pronounced grip |
| Body | BD | Thickness, weight, coating quality of the liquor | 7+ = dense, coating, substantial mouthfeel |
| Huigan | HG | Returning sweetness — speed, intensity, duration | 7+ = rapid onset, strong intensity, persists minutes |
| Flavor Transition | FT | How much the flavor changes across the steep progression | 7+ = dramatic arc, each steep reveals something new |
| Mineral | MN | Stony, metallic, wet-rock character | 7+ = defining characteristic (typical of yan cha, some aged sheng) |
| Finish Length | FL | How long flavor persists after swallowing | 7+ = lingers 30+ seconds with evolving character |
| Acidity | AC | Brightness, liveliness — distinct from astringency | 7+ = pronounced brightness (common in young sheng, dancong) |
| Steep Endurance | SE | How many productive steeps before flavor fades | 7+ = 12+ steeps maintaining complexity |
| Cha Qi | CQ | Body sensation beyond flavor | 7+ = clear body warmth, calm, or altered state. Scored only when unmistakable |
Scoring Scale
- 1-2: Absent or barely detectable
- 3-4: Present but mild
- 5-6: Moderate, clearly identifiable
- 7-8: Strong, a defining characteristic of this tea
- 9-10: Exceptional — among the best I’ve experienced in this dimension
The Total Score
The ten scores sum to a total out of 100. This total is not an overall quality rating. It is a profile shape.
A delicate Silver Needle white tea might score 38/100 — low body, low astringency, low mineral, moderate aroma and finish. A powerful aged sheng might score 72/100 — high across nearly every dimension. The Silver Needle is not worse than the aged sheng. They are different shapes. A Pinot Grigio is not worse than a Barolo because it scores lower on tannin and body. It’s a different wine designed for a different purpose.
The total is useful for comparing teas within a category — two shou pu-erhs with similar profiles but totals of 45 and 58 suggest the 58 is delivering more across the board. Across categories, the radar chart shape is more informative than the number.
Calibration Notes from My Practice
A few scoring decisions I’ve arrived at through sessions:
Mineral scores 2-3 unless I specifically detect mineral character. Most teas don’t have pronounced mineral expression. Wuyi yan cha is the exception — my Da Hong Pao scored mineral 8/10, the highest in my collection, because the rock rhyme (yan yun, 岩韵) is the dominant experience. Defaulting mineral to 2-3 unless actively detected prevents score inflation.
Cha qi scores 7+ only with clear body sensations. Not “I feel relaxed” — that could be the L-theanine, the warm liquid, or the act of sitting quietly. Cha qi 7+ means unmistakable physical response: warmth radiating through the chest, tingling, altered state. Conservative scoring protects the dimension’s meaning.
Astringency is not negative. A young sheng with astringency 7 is not penalized — that astringency is expected and contributes to the kugan (苦甘, bitter-sweet) conversion that defines the category. Astringency becomes a negative only when it’s harsh, metallic, or doesn’t convert to sweetness.
Flavor transition rewards change, not consistency. A tea that tastes the same across 12 steeps scores lower on transition than a tea that evolves from floral to mineral to sweet across 10 steeps. The dramatic arc IS the experience in gongfu brewing. A monotone tea can still score high on other dimensions — but transition captures something specific that matters.
Using the Protocol at Home
You don’t need to score all ten dimensions to start. Begin with three:
- What does it smell like? (Aroma — dry leaf and wet leaf)
- What does it taste like? (Flavor — front, mid, finish across multiple steeps)
- Does sweetness return after you swallow? (Huigan)
Those three observations, tracked across sessions, will develop your palate faster than reading any amount of tea content. The remaining seven dimensions reveal themselves as your sensitivity develops — you’ll start noticing body, mineral, qi, and steep endurance without deliberately looking for them.
Keep notes. Phone notes, paper notebook, voice memo — the format doesn’t matter. What matters is that you record something after every session, however brief. “Steep 3 was the best. Berry. Strong huigan. Hands warm.” That’s enough. That’s data. Over weeks, patterns emerge from your notes that you wouldn’t detect from individual sessions.
The gongfu brewing guide covers the practical method — vessel, water, parameters, and timing. The protocol on this page is the evaluation framework you layer on top of that method. Together, they form the complete Steep Atlas approach to tea.
Why Systematize?
Someone will ask — does scoring tea on ten dimensions make it less enjoyable? Doesn’t the spreadsheet kill the romance?
No. It does the opposite.
Systematic tasting teaches you to detect things you would otherwise miss. The first time I deliberately tracked huigan — timing it, noting the intensity, comparing it across teas — I realized I’d been swallowing and moving on for weeks without noticing the sweetness that arrived five seconds later. The protocol didn’t add a burden. It opened a channel.
The wine world figured this out decades ago. Nobody accuses a Master of Wine of enjoying wine less because they can identify the vineyard by the tannin structure. The vocabulary and the framework don’t diminish pleasure. They deepen it. They give you words for what you’re sensing, which makes the sensing itself more acute.
And on a personal level: the structured attention of a tasting session is the hour where my mind goes quiet. The protocol gives the session structure. Structure gives the attention somewhere to go. That’s not less enjoyable. For someone whose brain defaults to noise, it’s the most enjoyable hour of the day.
Frequently Asked Questions
What is the Steep Atlas Tasting Protocol?
The Steep Atlas Tasting Protocol is a standardized ten-dimension method for evaluating tea during gongfu brewing sessions. It uses a controlled setup (100ml white porcelain gaiwan, filtered water, measured leaf weight, temperature-matched water), a sequential evaluation process (dry leaf, wet aroma, steep-by-steep tasting, flavor synthesis, mouthfeel, qi), and a ten-dimension scoring system that generates a radar chart profile for each tea. The protocol is designed for reproducibility — anyone following the same parameters can compare their experience directly against documented sessions on this site.
Do I need special equipment to use the protocol?
At minimum: a white porcelain gaiwan (100-120ml), a digital scale, and a variable-temperature kettle. Total cost: $50-80. The gaiwan provides neutral evaluation conditions. The scale ensures consistent leaf dosing. The kettle controls water temperature. Everything else — tea tray, fairness pitcher, specific cup sizes — improves the experience but isn’t required for the evaluation itself.
Can I use this protocol for any tea?
The protocol is optimized for gongfu-brewed teas — pu-erh, oolong, dark tea, and red tea that reward multiple steeps. It can be adapted for green and white teas by adjusting the leaf amount and temperature per the parameter table. It is less suited to single-steep Western brewing because several dimensions (flavor transition, steep endurance) are only meaningful across multiple infusions.
How long does a protocol session take?
A full evaluation session — setup, rinse, 10-15 steeps, note-taking, scoring — takes 30 to 60 minutes depending on the tea and how many steeps you pursue. Quick informal sessions (scoring only the three core dimensions: aroma, flavor, huigan) take 15-20 minutes. The time investment is the practice. The practice is the point.
Is the ten-dimension total score a quality rating?
No. The total is a profile shape indicator, not a quality judgment. Different tea types produce different natural score ranges — a delicate green tea totaling 38 is not worse than a powerful aged sheng totaling 72. They are different shapes designed for different experiences. The total is most useful for comparing teas within the same category, where a higher total generally indicates more complexity and depth across the dimensions measured.
