Pu-erh, answered up front
Pu-erh is a dark, post-fermented tea from Yunnan province, made from a broad-leaf variety and sold almost always in pressed form - round cakes, rectangular bricks, bowl-shaped tuocha, or small mini cakes. Its defining feature is that the story does not end at drying: microbes keep working on the leaf over months and years, which is why pu-erh is described as living tea and why storage becomes part of the product. There are two distinct kinds. Raw pu-erh, called sheng, is sun-dried leaf that was pressed and now ages slowly on its own. Ripe pu-erh, called shu, went through a controlled wet-piling fermentation before pressing, so it arrives dark and drinkable. Same province, same leaf family, two different products on a wholesale list. Both start from the same sun-dried raw material, called maocha, and the fork comes later in the process - which is why the fork, not the leaf, is where most buying mistakes happen.
Raw and ripe are two different teas
The split matters commercially because the two kinds serve different buyers and behave differently in service. Raw is the tea house and connoisseur item, bought by material year and storage history; ripe is the foodservice and gifting item, forgiving and consistent. The desk keeps the comparison detailed in a separate note, and the summary below is enough to start a conversation.
| Aspect | Raw (sheng) | Ripe (shu) |
|---|---|---|
| Defining step | Sun-dried leaf pressed, then natural aging | Wet piling - controlled microbial fermentation before pressing |
| Liquor when young | Yellow-green to gold, bright | Chestnut red, deep and thick from the start |
| Cup character | Mid bitter-sweet edge, returning sweetness, builds with age | Earthy-mellow, smooth, coats the mouth, little bite |
| Buyers who order it | Tea houses, aged-tea retail, collectors' programs | Restaurants, hotels, gift boxes, everyday shelves |
| Brew reference | 5-7 g per 110 ml at 95-100 C | Same, with one rinse first |
Why the leaf is pressed at all
Pressing began as logistics: dense cakes traveled long distances on pack animals without crumbling, and the same density now makes warehousing and retail display practical. It also shapes the tea itself - a compressed cake exchanges moisture and air more slowly than loose leaf, which is exactly what slow raw-puer aging wants. The classic round cake weighs 357 grams and wraps seven to a bamboo tong, a trade convention with old transport arithmetic behind it; buyers today order other weights and formats freely, from 100 gram cakes to single-serve minis. The production sequence is simple to describe - steam the leaf, press it into shape, rest it to dry, wrap it in soft cotton paper - and the desk walks buyers through it on the processing page with photographs from partner facilities. For private label, formats run from the classic cake to bricks, bowl-shaped tuocha, and small single-serve rounds, each pressed denser or looser depending on how fast the program wants the tea to open in the pot.
What aging actually changes
In raw pu-erh, time converts the bright, bitter-edged young cup into something amber, mellow, and sweet, with the astringency retreating year by year; how far that has gone depends on temperature, humidity, airflow, and the leaf itself, which is why storage history is a buying question, not trivia. In ripe pu-erh the wet pile has already done the heavy lifting, so aging is gentler: the first months after processing let the fermentation edges settle and any pile notes disperse, after which the tea is stable and ready for service. Neither kind improves in a vacuum-sealed stall - both want breathable wrapping, stable conditions, and freedom from odors. Buyers who need the practical version should start with the desk's notes on storing pu-erh cakes and on humidity control before reserving shelf or warehouse space. A useful shorthand for the buying conversation: with raw, you are buying time and conditions; with ripe, you are buying a process result - and the paperwork should prove whichever one you are paying for.
Brewing with a rinse, and the chenpi variant
Service is gongfu at full boil: five to seven grams per 110 ml, water at one hundred degrees C, a first rinse of a few seconds that is poured off, then short infusions that stretch longer as the leaf opens. The rinse wakes the compressed leaf and carries away surface dust, and it matters more for ripe and aged lots than for young raw. On menus, pu-erh holds well in insulated servers and takes milk or citrus without collapsing, which is why restaurants like it for after-dinner service. The best-known variant is chenpi pu-erh - ripe tea aged or packed with dried tangerine peel from Xinhui in Guangdong - where the citrus-oil brightness cuts through the earthy depth, and retail customers who will not order plain ripe tea often accept it happily. Chenpi formats also rest well in a stockroom, which makes them a rare gifting line that improves on the shelf rather than fading on it.
Checks before a bulk pu-erh order
- Decide raw or ripe first, and within raw, decide young-drinking or age-worthy before comparing prices.
- For raw: material year, pressing year, and storage conditions recorded, not just a pretty wrapper.
- For ripe: fermentation batch records and a sample from the pile so pile notes never surprise you.
- Physical condition: clean cotton paper, sound cake edges, no mold spots, cartons free of foreign odors.
- Documents: origin records from Yunnan, batch retention samples, and a lab panel per lot for the program file.
Where pu-erh sells, and how to start
Tea houses sell pu-erh by the session and keep customers for years; retail sells it as format - mini cakes and wrapped tuocha that need no explanation; gifting buys ripe and chenpi formats because they read as substantial without needing education. The desk sources from Yunnan's producing regions, keeps retention samples per batch so a reorder tastes like the first order, and prices nothing until the program is specified - order sizes and preparation windows are reference ranges, confirmed in writing per program. Start from the pu-erh hub for the full line, compare the two kinds in the raw versus ripe note, and when you are ready to taste, send the quote form a short description of your channel and audience.
