The rooibos and honeybush sensory wheels serve as quality control and communication tools. The wheels provide industry role players with a tool to understand exactly what constitute the "characteristic aroma and taste" of these South African herbal teas.

The first generic rooibos sensory wheel, develop in 2011, was revised in 2017 to illustrate the relative importance of positive and negative aroma attributes in terms of intensity and occurrence.     

For honeybush tea, generic and species-specific sensory wheels were developed. The 2012 generic honeybush sensory wheel, compiled from the data of several Cyclopia species, was revised in 2020, based on a large sample set of C. intermedia ("bergtee"), C. subternata and C. genistoides. The generic sensory wheels do not capture the slight differences in the aroma profiles of the different Cyclopia species. For this reason, an aroma wheel was developed for C. intermedia, providing the bulk of honeybush production.
