Boiled and rubbed lactic tea
A pickled tea whose leaf is boiled in water rather than steamed above it, and then rubbed before it goes into the barrel. Both differences exist to produce something the other pickling routes do not have: a liquid to seal the leaf under.
What makes this route what it is
The fixation step produces two things and the route needs both. Every other kill-green in the catalogue is judged only by what it does to the leaf; here the water the leaf was boiled in is carried forward and becomes the medium the barrel is sealed under, which means the operation cannot be substituted with a steamer without changing a later step. It is the only route in the catalogue where the by-product of one step is an input to another.
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.
Mature summer leaf stripped from the branch by hand rather than picked shoot by shoot. Coarse, tough, cheap, and exactly what the route wants — a fine pluck would collapse in the barrel.
Boiled in a kettle of water rather than steamed above it. The leaf is fixed, and the liquor it was boiled in is kept, because step four needs it. This is the step that makes the route what it is and the reason it cannot share a record with the steamed pickled teas.
Rubbed by hand or in a machine to break the leaf surface. Not for shape and not for oxidation — the leaf has already been fixed — but so that bacteria can reach the inside of a mature leaf during the weeks in the barrel.
Packed into a wooden barrel with the boiling liquor poured back over it and a stone on top. Air is excluded by the liquid rather than by the leaf's own density, which is the practical consequence of steps two and three, and lactic acid bacteria dominate because nothing else can live there.
The mass is loosened out and dried in the open. Low temperature and no further heat, so the acidity that was built in the barrel survives into the finished tea rather than being cooked out of it.
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.
The rubbing. `seq-s32f-pickled` states that its leaf is never ruptured mechanically at all, and that statement is one of the more interesting things it says — a tea transformed entirely by organisms rather than by its own chemistry. It stops being true the moment this manufacture is put in the same record, which is why this is a route rather than an addition to that one.
One position in the route is filled by a different named method. The shape of the route is unchanged.
In the water rather than over it. The distinction sounds pedantic and is not: steaming leaves the maker with fixed leaf and nothing else, while boiling leaves them with fixed leaf and a barrel's worth of liquor, and the liquor is what this route seals the mass under. One operation, two sides of the water line, and a different fourth step at the end of it.
Where it goes wrong
The rubbing is the fragile decision. Too little and the bacteria cannot get into coarse mature leaf, so the barrel acidifies unevenly and the surface sours long before the core does; too much and the leaf breaks down into a mush that packs so densely the mass will not drain when it is opened. The barrel itself carries the other risk in a way no equipment note can settle: the population that does the work is resident in the wood and in the district, so a new barrel and an old one do not behave alike, and the practice regards that as a fact of the craft rather than a variable to be controlled.
In full
The catalogue's existing pickled route describes a manufacture in which leaf is steamed, packed tight under weights and sealed beneath its own liquid, and it says in as many words that no rolling happens anywhere in it. The Tokushima mountain tea does not fit that description and cannot be added to it without making the description false. Mature summer leaf is stripped from the branch by hand and dropped into a kettle of boiling water — not held above it — and the leaf and the water come out as two products of the same operation. The leaf is then rubbed, which the other pickling routes never do, to break its surface so that bacteria can reach the interior of a leaf that is coarse, tough and fully mature. Leaf and boiling liquor go into a wooden barrel together, a stone goes on top, and the mass is left for weeks while lactic acid bacteria acidify it. Then it is loosened out and dried in the sun. The result is sour and cider-like with almost no bitterness or astringency, and it is drunk locally as an ordinary everyday tea rather than kept as a curiosity — which is worth saying, because the catalogue's other pickled teas include one that is chewed rather than brewed and one that is genuinely rare.
