Rooibos Tea Proudly South African

Rooibos (Aspalathus linearis) is a shrubby legume indigenous to the mountains of the Western Cape and endemic to South Africa. It grows up to 1,5 m in height and has multiple thin branches with bright green, needle-like leaves.

The leaves (branches are cut 50 cm from the ground) are harvested and undergo the traditional process of fermentation which includes bruising and wetting the leaves with water and allowing it to ferment for 12 hours.

Enzymatic oxidation takes place and the leaves change from green to brown. Finally, the rooibos is spread out in the sun to dry. Green rooibos (unfermented) is harvested, cut and then dried immediately without fermentation, resulting in a tea with a lighter colour than traditional rooibos.

The plant adapts well to dryland conditions and prefers sandy soil with good drainage and pH of 4,5 to 5,5. Seeds are planted on seedbeds or plants may be propagated by cuttings. Leafhopper is a major pest as well as horsetail, a weed that grows alongside rooibos. This must be removed by hand or mechanically.
