My rolled oolong tastes of almost nothing

In short

Ball-rolled oolong needs a long first steep simply to begin opening. Applying a delicate-tea timing to it produces a cup made from the outside of the pellets only.

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. First infusion too short

   Under-extraction

   Check: Was the first steep ten to fifteen seconds, as it would be for a rock tea or a black tea?

   Fix: Give the first steep 20 to 25 seconds. Rolled pellets are effectively sealed until water has worked into them, and the first infusion is doing that work rather than making tea.

2. 2. Water too cool

   Temperature

   Check: Was the water below about 90 °C?

   Fix: Rolled oolong wants 90 to 95 °C. Cooler water will not open the leaf within a reasonable time.

3. 3. Vessel packed too full

   Leaf quantity

   Check: Did the leaf fill more than about a third of the vessel before brewing?

   Fix: The leaf expands many times over. Packed tight it cannot unfurl, and it will both under-extract early and over-extract later. Use less than looks right.

4. 4. Judged on the first cup alone

   Technique

   Check: Did you stop after one or two infusions?

   Fix: With rolled oolong the third and fourth infusions are frequently the best. The first is often the least representative cup in the session.

Tea types this applies to

• Oolong

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.

Guides covering this

• Leaf size, particle size and extraction rate — Break a leaf and you multiply the surface the water can work on. That single geometric fact explains most of the difference between whole leaf, broken leaf, dust and powder.
• Headspace, filters and drainage: the vessel decisions that are not about material — Arguments about teapots are almost always about what they are made of. Shape, filter design and how fast the thing empties decide more of the outcome, and none of them appears in the marketing.

Related problems

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

• 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.
• Every infusion in my gongfu session tastes the same — The cups are pleasant and interchangeable, with none of the change from steep to steep the method is supposed to show.
• 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.
• The dry leaf smells wonderful and the tea tastes of nothing — Opening the packet gives a strong, attractive aroma that has largely disappeared by the time the tea is in the cup.
• 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.
