Every infusion in my gongfu session tastes the same

In short

Showing a tea change across a session is the entire argument for gongfu brewing, and a flat session usually means the setup has quietly become western brewing with extra washing-up. Three parameters account for nearly all of it.

Likely causes, in order

Most likely first. Answer the question under each one before moving on — several of these look alike in the cup and are told apart only by what was done to the leaf.

1. 1. The vessel is too large for the amount of leaf

   Leaf quantity

   Check: Does the dry leaf fill a fifth to a third of the vessel, or a tenth?

   Fix: At a low ratio each steep is a dilute average rather than a distinct extraction. Raise the leaf and shorten the time; this is the change that transforms a flat session.

2. 2. Steep times not being adjusted

   Technique

   Check: Are you using the same number of seconds every time?

   Fix: Times start short and extend as the leaf gives out. Fixed timing across a session flattens exactly the differences you are brewing to hear.

3. 3. Pouring off incompletely

   Over-extraction

   Check: Is there liquor left in the vessel when you set it down?

   Fix: Empty it to the last drop. Liquid left behind keeps extracting at full strength and averages every subsequent infusion towards the same place.

4. 4. A tea that does not change much

   Leaf quality

   Check: Is it a simple everyday tea, a blend, or broken leaf?

   Fix: Not every tea has a session in it. Complex oolongs, aged dark tea and good sheng change markedly; a competent everyday black tea does not, and that is not a fault.

5. 5. Temperature drifting down through the session

   TemperatureInferred by TeaHQ, not established

   Check: Is the kettle holding temperature, or cooling between infusions?

   Fix: A falling temperature and a lengthening steep cancel each other out, which produces exactly this sameness. Keep the water hot and let the timing do the work.

Tea types this applies to

• Oolong
• Dark tea and pu-erh

Brewing methods this applies to

• Gongfu brewing (gaiwan) — A high-leaf, low-volume, many-infusions approach: a great deal of leaf in a small vessel, steeped for seconds at a time and poured off completely, repeatedly.
• Gongfu brewing (Yixing pot) — The same short-steep, high-leaf approach as gaiwan gongfu, carried out in a small unglazed clay pot that seasons over time and is dedicated to one tea.

Related problems

Sharing a cause category, a tea type or a brewing method with this one.

• My first infusion is always the worst one — The opening cup is thin, dusty or flat, and the second is markedly better — consistently, across different teas.
• My gongfu tea is bitter even at five seconds — The timer says five or ten seconds and the cup is over-extracted anyway, with the later infusions dropping off sharply.
• My roasted oolong tastes only of burnt toast — Char and ash dominate, and none of the fruit, mineral or floral character the tea was described as having comes through.
• My tea goes cold before I finish it — The cup is lukewarm within a few minutes, and in a gongfu session the later infusions arrive noticeably cooler than the early ones.
• My gaiwan is too hot to hold — The rim and lid become uncomfortable within seconds, the pour is rushed, and tea ends up on the tray.
