The Rooibos Patents Nestlé Quietly Let Lapse
In 2008 a Nestlé subsidiary filed five patents on rooibos and honeybush without the permit South African law required. None of them survive today, and the reason they vanished is quieter than most people expect.
Rooibos Is Legally Bound to One Region. Climate Models Say It Is Shrinking.
European and South African law both restrict the name rooibos to a narrow, delimited stretch of the Cederberg and its neighboring valleys. A peer-reviewed bioclimatic model, and the farmers already testing its warning in the field, say that exact ground is growing less suitable for the plant, with nowhere the name can legally follow it.
The Same Long Steep That Is Kind to Rooibos Is Not Kind to a Mesh Tea Bag
Rooibos rewards a long steep at a full boil with no bitterness penalty. That exact combination, near-boiling water held for many minutes, is also what tea-bag research finds strips the most microplastic out of a nylon or polypropylene mesh bag.
More of the Cederberg Is Under a Conservation Pact Than Under Rooibos
Rooibos farms in the Cederberg have signed more land into formal conservation agreements than the entire industry cultivates, a corridor that also keeps a camera-trapped leopard population, a dying cedar, and the plant's own wild backup moving.
