Honeybush is so named because the flowers smell of honey. The taste of honeybush tea is similar to that of rooibos but a little sweeter.

s and might be dependent on the services of particular ants or birds. ''Cyclopia intermedia'' (mountain tea) is one of the teas that is harvested in the
Kouga mountains where it grows naturally. Mountain tea regenerates within three years after harvesting or devastation by fire; consequently less than one third of the mountain yield is available for harvesting each year by rotation.
Mountain tea and valley tea flower in September/October whereas coastal tea flowers in May/June.
Tea preparation
There are two methods of processing honeybush for use in tea. In the traditional method, the leaves of the bush are harvested, cut and bruised (often with mechanical rollers), and then left in the sun to
oxidise
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is ...
. The modern, industrialised process oxidises the leaves in rotating, heated tanks at temperatures of 70–90 °C for two to three days. The leaves are then air-dried.
Afterwards, the leaves are sifted and graded according to the application:
* Super Fine (mostly used for string-and-tag tea bags)
* Regular Fine (mostly used for swimming tea bags or loose tea application)
* Coarse (mostly used for loose tea application)
