My pu-erh cake will not break apart cleanly

In short

Almost always tool and technique rather than the cake. Shredded leaf brews bitter and unevenly, so how the cake comes apart determines how it tastes — which makes this a flavour problem wearing a practical disguise.

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. Chopping downward instead of working along the layers

   Technique

   Check: Are you pressing the tool straight down into the face of the cake?

   Fix: Insert the pick at a shallow angle into the side of the cake and lever gently along the compression layers. The aim is to lift leaf out whole, never to cut through it.

2. 2. Using a sharp knife

   Equipment

   Check: Is the tool a blade with an edge?

   Fix: A sharp knife cuts the leaf rather than separating it, which is the one thing to avoid. A blunt flat pick, a butter knife or a flathead screwdriver all work better.

3. 3. Starting at the middle rather than the edge

   Technique

   Check: Where on the cake are you working?

   Fix: Start at the outer edge or at the dimple on the back, where compression is lowest, and work inward. The centre of a stone-pressed cake is the densest part.

4. 4. A very tightly machine-pressed cake

   Leaf quality

   Check: Is the cake hard and glassy rather than showing distinct leaf?

   Fix: Iron-pressed cakes are genuinely difficult and some are close to impossible to open neatly. Break off a larger chunk and let it loosen in the storage jar for a few weeks before brewing.

5. 5. The cake is very dry

   StorageInferred by TeaHQ, not established

   Check: Is it stored somewhere with very low humidity?

   Fix: A bone-dry cake shatters. Leave it in a stable, ventilated place with moderate humidity for a while; it becomes noticeably more workable.

Tea types this applies to

• Dark tea and pu-erh
• White tea

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.

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.
• My pu-erh tastes exactly the same as when I bought it — A cake bought several years ago to age has not noticeably changed, and it was stored carefully.
• My water is not the temperature the kettle says — The kettle is set to 80 °C and the tea behaves as though it were much hotter or much cooler, and the same setting gives different results on different days.
• 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 pu-erh or dark tea tastes sour — A sharp, tart, almost vinegary note runs through a ripe pu-erh, a sheng or another dark tea where the description promised earthy sweetness.
