Storage is the practice
A description of something people do now, compiled from published accounts rather than from practice.
For sheng pu-erh most of what determines the finished tea happens after it has been sold. Drier Hong Kong-style and more humid Guangdong-style storage produce recognisably different results from the same cake, and neither camp regards the other as correct. Serious storage involves controlled humidity, stable temperature, airflow and the deliberate absence of competing odours, and collectors discuss it in as much detail as the tea itself.
The speculative dimension, described rather than endorsed
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
Pu-erh has a secondary market with price movements, famous factory marks and recognisable speculative episodes. Age is widely treated as quality in itself and is not: a mediocre cake stored for twenty years is a twenty-year-old mediocre cake, and badly stored tea is spoiled rather than matured. Age claims on wrappers are unverifiable by a buyer, which is a structural feature of the market rather than an occasional problem.
What a newcomer should know
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
Buying pu-erh to age is a long-horizon activity with real uncertainty in both storage and market. Buying pu-erh to drink is straightforward and cheap. These are different activities and conflating them is how most people's first expensive mistake happens.
