Rooibos
Rooibos (Aspalathus linearis) grows almost exclusively in the Cederberg region of South Africa's Western and Northern Cape, making it one of the few herbal infusions with a single, tightly defined geographic origin. Red rooibos is fully oxidized, producing the familiar reddish-brown color and an earthy, vanilla-sweet, slightly woody character; green rooibos skips oxidation and retains a lighter, more vegetal profile closer to the fresh plant. The defining practical characteristic for brewing is the absence of tannins: rooibos does not get bitter regardless of steep time or water temperature.
Red rooibos should show a deep rust-red liquor, a clean sweetness with earthy and faint vanilla undertones, and a smooth, full body without any astringency. Thin, hay-like, or straw-forward character suggests low-grade or old leaf. Green rooibos is lighter in color (pale gold), grassier, and more delicate; it degrades faster than red and shows its age more clearly. Needle-grade rooibos (longer, thinner pieces of stem and leaf) is considered the quality benchmark; standard cut-grade is coarser and less nuanced. Genuine rooibos origin protection is the EU PDO (Protected Designation of Origin) granted in 2021, the first African product to receive it; the PDO logo is what appears on compliant European packaging.
The Cederberg region and its surrounds are effectively the only area where Aspalathus linearis grows commercially, giving rooibos a geographic exclusivity that most herbal infusions lack. The plant is native to a specific altitude and climate band; cultivation attempts elsewhere have not produced commercially viable results. Within the Cederberg, growing area, soil type, and harvest season produce variation in character, but these distinctions are less formalized than terroir in tea. Red rooibos accounts for the large majority of global supply; green rooibos is a smaller, more specialized production.
Western brewing is the standard approach: 3-4 g per 250 ml, boiling water, 5-7 minutes or longer. The absence of tannins means there is no penalty for extended steeping; many drinkers use 10-minute steeps without any bitterness. French press works well. Rooibos also performs in cold brew (8-12 hours in cold water) and holds up in milk-based preparations without flavor loss.
Red rooibos is among the most accessible quality herbal infusions; needle-grade and organic certified material commands a modest premium over standard cut. Green rooibos costs noticeably more due to lower production volume and shorter shelf life.

Red rooibos keeps well sealed away from light and moisture; most commercial red rooibos has a shelf life of two or more years without significant character loss. Green rooibos is more delicate and degrades faster; buy in smaller quantities and use within a year of production for best character.
Honeybush
Honeybush (Cyclopia species) grows in the same Western Cape region and is the closest natural relative in brewing character: sweeter, more distinctly floral, and with a lighter body than red rooibos.
Chamomile
Chamomile is the other widely recognized gentle, low-astringency infusion; it is distinctly floral and apple-like where rooibos is earthy and sweet, and the comparison clarifies the different flavor territory each covers.
Hibiscus
Hibiscus offers the tartness and acidity that rooibos entirely lacks; blending them is common precisely because they are so different, with rooibos softening hibiscus's sharp edge.
Green rooibos and red rooibos are the same plant material processed differently: green rooibos is dried quickly after harvest to stop oxidation, while red rooibos is allowed to oxidize (similar in concept to the difference between green and black tea, though the plants and chemistry are entirely different). The oxidation is what produces the characteristic red color and the vanilla-earthy flavor compounds.
