The tea I loved in the shop is disappointing at home

In short

Almost every variable changed between the two cups, and the leaf is the only one that did not. This is a different problem from a tea tasting different between purchases: here the tea is the same and the conditions around it are not.

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. Different water

   Water chemistry

   Check: Is the shop in the same water supply area, and do they filter?

   Fix: Try the tea with filtered or bottled water. Shops that sell tea seriously almost always filter, and water is the largest single variable between two kitchens.

2. 2. Different parameters, usually a much higher leaf ratio

   Leaf quantity

   Check: Was it brewed gongfu in the shop — a lot of leaf, a small vessel, seconds at a time?

   Fix: Ask what they used and reproduce it. A tea shown at 6 g in 100 ml for fifteen seconds is a different drink from 3 g in 300 ml for three minutes, and the second will not reveal what you bought.

3. 3. A single cup of one tea, tasted after several others

   TechniqueInferred by TeaHQ, not established

   Check: Had you tasted other teas immediately before it?

   Fix: Nothing to fix in the tea. A cup tasted in sequence against others is judged by contrast, and the same cup drunk alone at breakfast has nothing to stand against.

4. 4. Fresher leaf in the shop, from a larger and faster-moving stock

   StorageInferred by TeaHQ, not established

   Check: How long has your packet been open, and how is it stored?

   Fix: For aromatic teas, buy smaller quantities more often and keep them airtight. A shop opening a fresh caddy daily is showing you the tea at its best.

5. 5. Vessel and temperature

   EquipmentInferred by TeaHQ, not established

   Check: Was it brewed in porcelain or glass in the shop, and in a large metal or thick clay pot at home?

   Fix: Match the vessel type if you can, and preheat. Heat retention and material both shift the result, and a big cold pot changes a delicate tea considerably.

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.
• Western brewing (teapot or mug) — A small amount of leaf in a large volume of water, steeped once for a few minutes and then strained off. The approach most English-speaking drinkers already know, and the one most teas sold in the West are made for.

Related problems

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

• My teapot came out of the dishwasher damaged or tasting wrong — A pot or cup returns from a dishwasher cycle dulled, with faded decoration, a fine web of surface cracks, or a persistent taste that was not there before.
• I filtered my water and the tea got worse — After switching to filtered, distilled or reverse-osmosis water the tea is cleaner and emptier — no off-notes, and no body either. It tastes thin and slightly hollow.
• My green tea tastes flat and looks dark in this house — A delicate green tea that tasted bright elsewhere comes out dull and heavy here, with a darker, browner liquor than it should have and none of its aroma.
• 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.
• I cannot taste the difference between my expensive tea and my cheap one — Two teas at very different prices taste much the same in the cup, and the tasting notes on both packets describe things you cannot find.
