This is a dated storage note rather than a declaration that I have solved aging. The comparison is ventilation: closed plastic box versus vented cabinet with humidity monitoring. storage aroma reduced over two months.

Climate and measurement matter here. If your storage is in a different humidity range, please label it. Failure reports are useful too; I would rather know what went wrong than build a shrine to survivorship bias.

Long-term report
Direct recommendation: repeat the session with vented cabinet with humidity monitoring.
Applies to: Harbor Brick 2019 sheng / puer storage log in a setup close to 100 ml porcelain gaiwan.
Evidence: measured storage in a similar climate.
Change: repeat the session with vented cabinet with humidity monitoring.
Expected effect: the cup should move toward separate pleasant humid aging from storage damage if that variable is causal.
Observed result: storage aroma reduced over two months.
Limitations: I would stop if the change removes the aroma you are trying to preserve.
Commercial relationship: none.
