How to Use

  1. 1
    Enter your vessel capacity

    Input the volume of your gaiwan or teapot in milliliters—typically 80–150 ml for gongfu vessels—to calibrate leaf weight and water amount.

  2. 2
    Select your tea type

    Choose from the tea category and specific variety to retrieve recommended leaf weight, water temperature, and the timing structure for an extended multi-infusion sequence.

  3. 3
    Follow the infusion schedule

    Use the displayed timing progression for each successive infusion, noting that steeping times typically increase by 5–15 seconds per round to maintain consistent extraction across the session.

About

Gongfu brewing is a precision practice, and the variables that govern each session—vessel size, leaf weight, water temperature, and infusion timing—interact in ways that reward systematic calculation over intuition alone. The Gongfu Calculator provides a personalized brewing scaffold: enter your vessel's capacity and tea type, and receive a complete infusion schedule calibrated to your specific equipment and leaf, from the first flash steep through the final productive infusion.

The calculator draws on leaf-to-water ratios and temperature parameters derived from established Chinese and Taiwanese tea preparation traditions as interpreted through contemporary specialty tea pedagogy. Timing progressions are built around the principle that leaf hydration progresses across a session—early infusions require minimal time because the leaf is fresh and reactive, while later rounds need progressively longer steeping to maintain extraction as the leaf becomes spent. The starting times and increment recommendations reflect this hydration curve for each tea category.

For both beginners encountering gongfu for the first time and experienced brewers working with an unfamiliar vessel size or new tea type, the calculator provides a calibrated starting point that eliminates guesswork without removing the experiential learning that makes gongfu brewing rewarding. The specific timing values should be understood as evidence-based defaults, not prescriptions—personal taste, water mineral content, and leaf grade all create legitimate reasons to adjust from the calculator's baseline.

FAQ

What does "gongfu" mean in the context of tea brewing?
Gongfu (功夫茶, also romanized as kung fu cha) translates roughly as "tea with skill" or "tea made with effort and mastery," reflecting a philosophy of deliberate, attentive brewing that aims to extract every dimension of a tea's character across multiple short infusions. The practice originated in Chaoshan (Chaozhou-Shantou) in Guangdong province and evolved through Fujian and Taiwan where oolong and pu-erh cultures developed it into a comprehensive aesthetic and social practice. The defining characteristics are high leaf-to-water ratios (often 5–10 grams per 100 ml), small vessel sizes (80–200 ml gaiwan or teapot), very short steep times (15–60 seconds), and many sequential infusions—sometimes 10 to 20 or more—from a single portion of leaf. Each infusion is considered a chapter revealing different aspects of the tea as leaves hydrate progressively.
How do I calculate the correct leaf weight for my vessel?
The standard gongfu leaf-to-water ratio varies by tea category because different leaf forms and densities fill a vessel differently. Rolled or balled oolongs like Tie Guan Yin or Four Seasons use approximately 5–7 grams per 100 ml because the compact pellets take more water to fully open. Twisted leaf oolongs and black teas typically use 4–6 grams per 100 ml. Flattened green teas (longjing, bi luo chun) are more delicate and use 3–5 grams per 100 ml. Pu-erh compressed cakes typically require 6–8 grams per 100 ml depending on compression density. These ratios result in a vessel that appears approximately 20–30% filled with dry leaf—after infusion, hydrated leaves should nearly fill the vessel. A gram scale accurate to 0.1 grams is considered essential equipment for consistent gongfu results.
How do I know when to end a tea's session and discard the leaves?
The right moment to finish a gongfu session is when the infusions lose meaningful flavor complexity rather than at a fixed infusion count. High-quality teas often support 8–15 infusions; exceptional aged pu-erh and high-mountain oolongs can occasionally produce 20 or more distinctive cups. Practical signs that a session has concluded include significantly faded liquor color, loss of aromatic complexity in the cup, flat or wan flavor lacking structure, or the taste becoming thin and watery without the sweetness or mouthfeel of earlier infusions. Some tea drinkers intentionally push beyond productive infusions to appreciate the gradual transformation. The leaf's physical appearance after the session—fully opened and expanded—confirms the tea was fully worked. Spent gongfu leaves can be examined for quality clues: whole, undamaged leaves with even coloration indicate good-quality material.
Can I use gongfu brewing with all tea types?
Gongfu technique is most commonly applied to oolongs, pu-erh, and some black teas where the multi-infusion revelation of character is most pronounced, but the approach works with essentially any tea type when adapted. Japanese green teas are rarely brewed gongfu-style in their native tradition, but enthusiasts do apply the method to gyokuro and high-grade sencha, using lower temperatures (55–65°C) and short 30–45 second steepings. White teas, particularly aged white peonies (Bai Mu Dan) and silver needle (Bai Hao Yin Zhen), respond very well to gongfu brewing and can yield 6–10 interesting infusions. Herbal tisanes technically cannot be brewed gongfu due to their single-use nature (most herbs do not re-steep meaningfully), but highly compressed herb blends with dense material may yield 2–3 infusions. The key is adjusting temperature and timing parameters to the specific material rather than applying oolong parameters universally.
What is the difference between a gaiwan and a teapot for gongfu brewing?
A gaiwan (盖碗, "lidded bowl") is an unglazed or glazed ceramic vessel with a lid and saucer, used for both brewing and drinking directly or for pouring into a sharing pitcher. Its principal advantage is neutrality: the gaiwan imparts no flavor to the tea, making it ideal for evaluating new teas or switching between different types in the same session. The wide opening facilitates easy leaf inspection and aroma assessment. A traditional yixing teapot made from Zisha (purple clay) from the Yixing region of Jiangsu province is prized by devoted tea practitioners for its micro-porous clay structure, which is said to absorb oils from repeated use over years, becoming seasoned to specific tea types. Dedicated yixing pots are ideally used with one tea category only to preserve this seasoned character. Both vessels function equally well for the mechanics of gongfu brewing; the choice is a matter of preference, budget, and the level of connoisseurship one is pursuing.
