Rooibos tea can now only be made by South African rooibos tea manufacturers after the tea was granted geographic indicator status under the economic partnership agreement between southern African nations and the European Union.
Minister Rob Davies made the announcement on Monday.
"It will be the rooibos tea manufacturers of South Africa which will have ownership of that particular name and that term will be applicable only to products that come from and are approved by us," Davies said in a Sapa report.
The tussle over the rooibos name came after a French company, the Compagnie de Trucy, tried to trademark the name last year. The trademark bid was opposed by the the South African Rooibos Council.
Honeybush tea and Karoo lamb were also granted the same status. This means that only products produced in the areas can be marketed under those names.
South Africa though had to make a concession on feta cheese which has reportedly been a protected designation of origin product in the EU since 2002.
Minister Davies explained that existing SA manufacturers of feta cheese would be allowed to continue making the cheese but new manufacturers would be barred from doing so.
The partnership deal also saw number of South African wines given geographic name protection similar to that enjoyed by French wines from Bordeaux and Champagne. South Africa will also be allowed to export more wine to Europe tariff-free every year, with the volume more than doubling from 47 million litres to 110 million litres.
South Africa will also be allowed to ship 150 000 tons of sugar to Europe tariff-free every year.
