Pressed and aged white tea
The withered-and-dried route with a pressing tail bolted on, borrowed wholesale from dark tea and applied to a leaf that was never fixed and never rolled.
What makes this route what it is
It is the only route in the catalogue where a whole post-manufacture tail is transplanted from one category to another. Everything from the steaming onwards is dark tea practice; everything before it is white tea practice; and the leaf in the middle was never fixed, which is why the ageing that follows behaves unlike a sheng cake's despite the identical machinery.
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.
Cakes are made across the grade range, but the leafier grades dominate — they survive pressing better and the economics of tying up bud-grade tea for years rarely work.
Identical to the loose route. The tea being pressed is a finished white tea, not a half-made one.

Drying
The tea is finished here. Everything after this point acts on a completed product, which is what makes the rest of this route a post-manufacture tail rather than part of the manufacture.
Far gentler than for maocha: withered white leaf is brittle and thin, and over-steaming it produces a cake that has been part-cooked before it starts ageing.
Cakes, small nests and bricks. Pressed loosely by the standards of pu-erh, because the leaf will not tolerate the force a hydraulic press applies to maocha.
The moisture the steam introduced has to leave a compressed mass slowly. A white cake dried hot arrives baked and goes no further.
The point of the whole tail. The cake changes more slowly and more evenly than loose leaf of the same tea would, and that evenness is the argument for pressing at all.
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.
The two routes are the same tea up to a point. Everything before the divergence is shared; everything after it is not.
Identical through the drying. At step four one route stops and sells a finished tea, and the other steams that finished tea and starts again. Nothing about the leaf differs; only what is done to it afterwards.
This route leaves out an operation the other performs. Omissions are usually irreversible — the step cannot be added back later.
The sheng route fixes and rolls before it sun-dries; this route does neither. Two cakes that look alike, press alike and are stored alike therefore age by different mechanisms, and the pu-erh trade's expectations about ageing transfer to white tea much less cleanly than the shared shape suggests.
In full
Compression arrived in white tea from the pu-erh trade and it changed what the category is for. A finished white tea is steamed briefly until it is pliable, pressed into a cake or a small nest, dried slowly, and then stored. Nothing about the leaf is different from the loose version; what changes is the geometry of storage. A cake exposes far less surface to the air than the same weight of loose leaf, so it changes more slowly and much more evenly, and the sweet, dried-fruit and faintly medicinal character that aged white is bought for develops in a way that a loose bag of the same tea does not reproduce. The route is also commercially convenient in a way worth stating plainly: cakes stack, ship and store where loose white tea — which is bulky, fragile and hygroscopic — does none of those things well.
