I have reached the stage where changing three things at once is only producing new kinds of confusion. The cup is giving me good texture but very little aroma compared with vendor notes. The last controlled change was temperature: 90°C to 95°C, and body improved but aroma barely changed. I would like the next test to be one variable only. If you have brewed this exact tea, or something genuinely comparable in a similar vessel, that would be especially useful.

My target is simple: bring out florals without making the tea thin. I am not looking for a new shopping list unless the equipment is actually the problem.

Tested solution
Direct recommendation: increase water mineral content modestly to around 60 ppm.
Applies to: Cloud Pass 2026 Qingxin / Taiwan high-mountain oolong in a setup close to gaiwan.
Evidence: firsthand test by the questioner on Cloud Pass 2026 Qingxin.
Change: increase water mineral content modestly to around 60 ppm.
Expected effect: stronger aroma definition and slightly firmer structure.
Observed result: body improved but aroma barely changed.
Limitations: If your actual filled volume differs from the stated volume, the ratio may be the bigger issue.
Commercial relationship: none.

Applies to: Cloud Pass 2026 Qingxin / Taiwan high-mountain oolong in a setup close to gaiwan.
Evidence: firsthand use of the same Cloud Pass 2026 Qingxin in a closely matched setup.
Change: preheat the gaiwan and cup more thoroughly.
Expected effect: more obvious florals without changing extraction.

Comparable tea
Direct recommendation: reduce first steep to 15 seconds and smell the lid immediately.
Applies to: Cloud Pass 2026 Qingxin / Taiwan high-mountain oolong in a setup close to gaiwan.
Evidence: firsthand use of a comparable Taiwan high-mountain oolong with similar parameters.
Change: reduce first steep to 15 seconds and smell the lid immediately.
Expected effect: brighter high notes and less cooked-green character.
Observed result: not tested on this exact setup yet.
Limitations: My result is from a small number of sessions, so treat it as evidence rather than law.
Commercial relationship: none.

Controlled test
Direct recommendation: increase water mineral content modestly to around 60 ppm.
Applies to: Cloud Pass 2026 Qingxin / Taiwan high-mountain oolong in a setup close to gaiwan.
Evidence: side-by-side or repeated one-variable test.
Change: increase water mineral content modestly to around 60 ppm.
Expected effect: stronger aroma definition and slightly firmer structure.
Observed result: not tested on this exact setup yet.
Limitations: I would stop if the change removes the aroma you are trying to preserve.
Commercial relationship: none.
