As soon as they are plucked, the rooibos shoots are cut and sprinkled with water. Then the oxidation process can begin. This takes place outside and causes the leaves to change colour, from green to brown. When it has oxidised to the right degree, the rooibos is spread out on the ground in a fairly thin layer, so it can dry in the sun.
The oxidation of rooibos

Very interesting! It looks like red clay soil.
Thanks for sharing. François-Xavier, What motivated you to call this blog “The oxidation of rooibos”, not that the title does not go with the content, I am just wondering. Congratulations again on a good job François-Xavier.
