Rooibos: the red bush of the Cederberg

The Cederberg mountains rise sharply about two hundred kilometres north of Cape Town. In summer the heat is dry and the rock looks orange in the late light. Along the lower slopes, in pockets of sandy soil, grows a shrub with needle-like green leaves that turn rust-red when cut and laid out to dry. This is Aspalathus linearis, the red bush, and its leaves make rooibos.

The plant is endemic to this small region. It grows almost nowhere else in any commercial way. The flavour is unmistakable: warm, slightly sweet, faintly woody, with a softness that some people describe as honeyed and others as caramel. It is naturally caffeine-free.

A small history

Rooibos has been used by the indigenous Khoisan peoples of the western Cape for centuries, though detailed records are scarce. The plant is mentioned in Dutch botanical writings from the eighteenth century. As a commercial beverage, however, rooibos really emerged only in the early twentieth century, when a Russian-born merchant named Benjamin Ginsberg began promoting it as a local alternative to imported black tea, which was expensive and reliant on shipping routes that wartime disrupted.

The first proper commercial cultivation, as opposed to wild harvesting, began in the 1930s. South African farmers in the Clanwilliam area worked out how to grow the plant from seed at scale, a difficult task because the seeds are tiny and germinate erratically. By the second half of the twentieth century, rooibos had become a fixed part of the South African pantry, taken with milk and sugar in many homes the way English-style black tea was elsewhere.

The fermented and the green

There are two main forms. The familiar red rooibos is fermented, meaning the cut leaves are bruised, piled in mounds, and allowed to oxidize for several hours in the dry Cederberg heat. This process turns them from green to rust-red and develops the sweet, full-bodied flavour most people know.

Green rooibos, sometimes called unfermented rooibos, skips this oxidation step. The leaves are dried quickly to lock in their original colour and a fresher, grassier taste. It is lighter and less sweet than the red. Both come from the same plant. The processing is what distinguishes them.

“It is the tea of this country in the way bread is the bread of this country. There is no other one.” (recorded from a small farm shop near Clanwilliam, 2016)

How South Africans make it

The household method is simple. A teaspoon of rooibos per cup is placed in a teapot or a small saucepan. Boiling water is poured over, and the brew is left to steep for five to seven minutes. Unlike green tea, rooibos does not turn bitter with long steeping, so the time is forgiving. In many homes the pot sits on the counter for an hour and is reheated.

It is taken hot, often with milk and a small spoon of sugar, the way one might take English breakfast tea. Some prefer it black, particularly when the leaves are good quality and from a single estate. In summer, it is brewed strong and chilled, sometimes with a slice of lemon or a sprig of mint added to the pitcher.

The cup in the larger day

Because rooibos has no caffeine, it occupies a particular slot in South African homes. It is the cup that can be taken at any time of day, including evening, without the household conversation around sleep. It is also, traditionally, one of the first warm drinks given to small children, and it is the cup offered to elderly relatives who have stopped drinking coffee.

Readers familiar with our broader notes on comfort and relaxation rituals will recognize this pattern. Many cultures have one drink that fills exactly this position: warm, gentle, suitable for any age and any hour. In southern Africa, that drink is most often rooibos.

What pairs with it

Rooibos pairs naturally with rusks, the hard sweet biscuits that South African households dunk into hot drinks. It also goes with honey, with a thin slice of bread and butter, and with the various dried fruits of the western Cape. Some households add a single clove or a piece of cinnamon stick to the pot in winter, which gives a slight warmth without altering the rooibos itself too much.

In more recent years, rooibos has also become the base for various blends, some of which pair it with vanilla, citrus peel, or chocolate. These blends are common in cafes but somewhat less so in older household kitchens, where the plain leaf remains the standard.

The Cederberg, the rock, and the wind

Visiting the area where rooibos grows is part of why some people change their relationship with the cup. The landscape is austere: red sandstone, scattered shrubs, very dry air. The light is sharp. There is almost no shade. The plant, growing in this difficult soil, takes on a quiet meaning.

This is one of the small reasons that rooibos is more than just a tea in South Africa. It carries a sense of place. A pot of it, made well, smells faintly of the country it comes from. Readers who follow our notes on seasonal living often write about adopting a rooibos habit in the autumn, when the body asks for something warmer and lower-pitched than summer drinks.

Comparing it to other caffeine-free options

Rooibos is sometimes grouped with chamomile and other evening brews, but it is structurally different. Chamomile is a flower; rooibos is a shrub leaf. The character is richer, fuller, more like a proper tea in body. For those moving away from caffeinated drinks in the afternoon, it tends to be a smoother transition than, for example, jumping straight to chamomile or to a cup of cinnamon bark in warm water.

It is also one of the few traditional brews that takes milk well. Most herbal infusions are taken plain. Rooibos, almost alone among the caffeine-free options, can carry milk and sugar comfortably.

A quiet word of care

Rooibos is broadly considered gentle and is given to children and the elderly in its home country. Anyone with specific health concerns, on regular medication, or pregnant will sensibly check with a qualified practitioner before making any new herb a daily habit. This is more courtesy than caution.

The teapot, when the round is done, holds a warm, rust-red residue that gives the next pot a slightly deeper colour. Some households like this. Others rinse the pot. Either way, the leaves go back into the tin, the cups into the sink, the kettle onto the next thing.

The wind across the Cederberg slopes is dry. The cup is warm. Both, for a moment, belong to the same afternoon.
