Tea manufacture is mechanised
Rolling by hand, then by machine. The single technological change that made tea a mass commodity rather than a craft product, and the reason a plantation could process what a plantation could pick.
From the 1870s
A process, not a moment. This happened over a period rather than on a date, and the span is the honest answer.
TeaHQ synthesis. TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
What happened
Rolling machines, mechanical driers and sorting equipment replaced hand manufacture on colonial estates through the 1870s and 1880s. Output per worker rose sharply and manufacture moved from a skilled hand process into a factory operating to a specification.
Why it matters
It decoupled production volume from skilled labour, which is what allowed tea to become cheap enough to be an everyday drink across Europe. It also standardised the product: the point of a machine is that it does the same thing every time, and consistent blended tea is a machine-age idea.
