Holding maocha before pressing
Sun-dried maocha is frequently kept loose for months or years before anyone presses it, which means a cake's date is the date of its pressing and not of its leaf.
The categories this step defines
In tea, processing is not a modifier applied to a category — it is what creates the category. These are the types that exist because this step exists.
- Dark tea and pu-erh — Post-fermentation: microbial wet-piling (shou) or extended natural ageing (sheng).
What it is
There is no rule that a spring's maocha must be pressed that spring. Producers and traders hold sun-dried loose leaf — because they are accumulating enough of one area to make a batch, because they are waiting for a price, because a blend calls for material of more than one year, or because loose leaf in a dry warehouse changes in a way some makers prefer to the same period spent inside a cake. Loose maocha has far more surface exposed than a pressed one, so it changes faster and less evenly, and a year loose is not equivalent to a year pressed. The consequence for a buyer is precise and often missed: the year printed on a wrapper is the pressing year, and it constrains the leaf's age only from above. A cake pressed in 2020 may contain material picked in 2020, or in 2016, or a deliberate mixture, and none of those is dishonest as long as nobody claims otherwise.
Also transliterated as: mao cha cun fang, maocha cunfang.
What it does to the leaf
Stores finished sun-dried loose leaf under ambient conditions between manufacture and compression, during which it continues to change at the faster, less even rate that loose leaf changes at.
What it does to the cup
A year or two loose takes the sharp edge off young sheng and is associated with a rounder, quieter cake at pressing; long or careless loose storage flattens the material before it is ever compressed.
Variants that matter
Ways this step is carried out that produce genuinely different results, rather than regional names for the same thing.
- Accumulating a batch
- Buying maocha across a season or several to reach a viable pressing quantity. The ordinary commercial reason, and it makes single-day cakes rare.
- Deliberate loose ageing
- Held on purpose for a period before pressing, on the argument that the two kinds of change are complementary. A producer preference rather than an established practice.
- Loose sale without pressing
- Maocha sold and drunk as loose leaf. A real product in Yunnan, and the format in which most producers taste their own material.
Where this gets misdescribed
A pressing year is read as a harvest year. It is neither a harvest year nor a claim about one, and the gap between the two is the ordinary condition of the trade rather than a sign of deception — which is why a specific vintage claim about a cake needs more support than the number on the wrapper.
Other steps at the Ageing and storage stage
- Ageing and storage — Deliberate long-term storage under which a finished tea keeps changing, rather than merely keeping.
- Basket ageing — Ageing dark tea packed into woven bamboo baskets, which contribute aroma and regulate airflow.
- Warehouse storage and airing (ru cang, tui cang) — The deliberate two-phase Hong Kong practice of holding cakes in a humid warehouse and then airing them in a dry one for years before sale.
Guides covering this step
- Sheng and shou: five identical steps and one fork — Raw and ripe pu-erh are made the same way for five operations and then part company at one. Everything the trade argues about turns on what sits in that fork, and nothing at all before it differs.
