Basket drying (hong gan)
Drying leaf in a woven basket over a low charcoal or electric heat source rather than in a pan or a hot-air machine.
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.
- Green tea — Kill-green (fixation) applied before meaningful oxidation can develop.
What it is
How a Chinese green tea is dried is one of the standard ways the category is subdivided, and basket-dried greens — hong qing — form a large family: Huangshan Maofeng, Taiping Houkui, Liu An Gua Pian and most of the base leaf used for jasmine scenting. Leaf sits on a mesh-topped bamboo basket set over a firebox, drying in still, radiant heat rather than by contact with metal or by forced air. The result is a leaf that stays open and loose rather than being tightened by pan pressure, and a cup that is clean, floral and comparatively light, without the chestnut note that pan-dried greens carry. The same equipment, run hotter and longer, becomes the roasting basket used for oolong, which is why the vocabulary of drying and roasting overlaps in Chinese as much as it does in English.
Also transliterated as: hong gan, honggan, hong qing.
What it does to the leaf
Dries leaf by still radiant and convective heat in a basket above a low fire, without pressing or tumbling it against a hot surface.
What it does to the cup
Keeps the leaf open and the cup light and floral; contributes markedly less toasted character than pan drying and slightly more than neutral hot-air drying.
Variants that matter
Ways this step is carried out that produce genuinely different results, rather than regional names for the same thing.
- Charcoal basket
- The traditional form, over banked charcoal covered with ash to even the heat. Labour-intensive and still used for high grades.
- Electric drying cabinets
- The volume equivalent, with trays in a heated chamber. It reproduces the still-air principle without the fire management.
- Hot-air conveyor drying
- Forced air through moving leaf. Fastest and most neutral of the three, and the reason a great deal of commodity green tea tastes of nothing in particular.
Where this gets misdescribed
Basket-dried and pan-dried greens are often compared as if one were the traditional method and the other the modern one. Both are old, both are current, and they define different tea families: a Longjing dried in a basket would not be Longjing, and a Taiping Houkui pressed in a pan would not be Houkui.
Other steps at the Drying stage
- Drying — The final moisture reduction that halts change in the leaf and makes the tea stable enough to keep.
- Drying the pressed cake — A freshly pressed cake is wet in the middle, and how that moisture is taken out over the following days is one of the least visible and most consequential decisions in dark tea.
- Pulling the old fire (la lao huo) — A final drying method in which a basket of tea is carried over an intense charcoal fire for a second or two at a time, again and again, by a relay of workers.
- Sun-drying (shai qing) — Drying leaf in sunlight rather than in a machine, leaving residual enzyme and microbial activity intact.
- Two-stage drying (mao huo and zu huo) — Drying in two passes with a cooling interval between them, because moisture inside the leaf needs time to migrate to the surface.

Written comparisons
Where TeaHQ has set this step against something it is routinely confused with, and argued the differences out in full.
- Basket drying vs pulling the old fire — Both dry leaf in a basket over charcoal and they could hardly be more different in intensity. Basket drying is still, low and patient; la lao huo carries the basket over an intense fire for a second or two at a time, again and again, passed between a relay of workers.
- Two-stage drying vs basket drying — Drying is the step that decides whether a tea keeps, and the two traditional approaches solve different halves of the problem. Staged drying addresses the physics of moisture migration; basket drying addresses how heat reaches the leaf without pressing or tumbling it.
