Coarse yellow tea with a high finishing fire
The yellow tea that behaves like a dark tea. Coarse leaf and stem, yellowed in bulk rather than in a wrapper, and finished with a fire long and hot enough that the roast becomes the tea's main character.
What makes this route what it is
The yellowing is no longer the loudest step. In every other yellow tea the smother is the whole product and the fire is a finish; here the fire is prolonged so far that it dominates a tea which is still, structurally, made by the yellow tea route. It is the best demonstration available that a category name records a manufacturing step rather than a promise about the cup.
The route, in order
Each note describes what the step is doing in this route. The same operation does a different job in a different chain.
An open shoot of four or five leaves with stem attached, taken late. The stem is not a defect to be picked out here — it carries sugars that the long fire at the end works on, and a stemless version of this tea would be a poorer one.
Hot, fast wok fixation on coarse material. The heat has to reach through much thicker leaf than a bud tea presents, which is why it is run harder than a Longjing's fixation and why some scorching at this stage is expected rather than avoided.
A rough roll that breaks the leaf's structure enough for the later steps to reach into it. Shape is not a consideration in this tea and no effort is spent on it.
A first fire over baskets, taking the leaf part-way down in moisture. This is what makes the yellowing that follows a dry-blank operation rather than a wet one, and it is why the change can be allowed to run for days without going sour.
Yellowing in bulk — heaped or packed into baskets, sometimes for several days — rather than wrapped in paper and opened on a schedule. The bud teas' smother is a delicate, closely watched operation; this one is closer to leaving a large quantity of warm leaf to come round in its own time.
Pulling the old fire: a prolonged high-heat basket roast over charcoal, far beyond any finishing bake, until the leaf carries a scorched-grain and burnt-sugar character. This is the step the tea is named and sold for, and it has no counterpart anywhere else in the yellow category.
How it differs from its neighbours
A route described on its own teaches very little. The useful fact is always which other route it is nearly identical to, and where it leaves it.
This route inserts an operation the other does not have. Nothing is substituted and nothing is removed.
Add one prolonged fire to the end of the yellow tea route and the category's usual reading stops working. Nothing is removed — the fixation and the smother are both there, in their usual positions — but the finishing operation is run so far past its normal setting that a drinker meets roast before they meet anything the yellowing did.
One position in the route is filled by a different named method. The shape of the route is unchanged.
The same slot, filled by bulk heaping instead of a wrapped and repeatedly opened parcel. The bud teas' version is judged by opening, looking and re-wrapping; this one is judged by leaving a mass of coarse leaf alone for days. Both are men huang and the amount of attention they receive differs by an order of magnitude.
The two routes are the same tea up to a point. Everything before the divergence is shared; everything after it is not.
Two routes in two categories whose final step is a fire pushed past the point where it produces the tea it started as. Hojicha's setting change happens to a finished Japanese green tea; this one happens inside a yellow tea route that has not finished yet. That both arrive at a roasted, grain-sweet cup from opposite ends of the catalogue is an argument that the roast is a stronger determinant of a drinker's experience than the category ever was.
Where it goes wrong
The long fire is the danger and the attraction at once. Pushed too far it stops being caramelised and becomes ashy, and there is no recovering it; stopped short, the tea is a coarse yellow tea with nothing to recommend it, because the material was never fine enough to stand on its own. The margin is wide compared with a bud tea's smother and it is not infinite.
In full
The surviving yellow teas are almost all bud teas made in tiny quantities, and the route the catalogue already holds describes them: fix, smother in a wrapper, bake gently, sort. Huang Da Cha is made on the opposite principle at every point. The pluck is deliberately coarse — an open shoot of four or five leaves with a length of stem, the sort of material every other famous-name Chinese tea is defined by refusing — and it is fixed hot and fast in a wok, rolled roughly, and given a first fire. The yellowing then happens in bulk: the part-dried leaf is heaped or basketed, often for days, without the wrapping and unwrapping cycle that governs the bud teas. Finally comes the step that makes the category, la lao huo, pulling the old fire — a prolonged high-heat basket roast over charcoal that goes far beyond a finishing bake and gives the tea a scorched-grain, burnt-sugar character that the trade compares to roasted barley. What comes out is a yellow tea by manufacture and, in every practical respect a drinker cares about, a dark roasted one: cheap, robust, long-keeping and brewed strong.
