Rooibos Tea: South Africa's Most Underrated Loose Leaf Tea

Chai Society Ruby Sundara loose leaf rooibos blend canister

Rooibos tea is not technically a tea at all, and that is exactly what makes it worth understanding. It comes from Aspalathus linearis, a needle-leafed shrub that grows in one place on earth, the Cederberg mountains of the Western Cape. Everything South Africans love about it, the deep red colour, the soft natural sweetness, the fact that you can pour a cup at nine in the evening without a second thought, comes from that one plant in that one stretch of soil.

Most of us grew up with rooibos in a bag, drunk quickly and without much ceremony. Loose leaf rooibos is a different experience, and it is the most quietly remarkable thing South Africa puts in a cup.

What exactly is rooibos tea?

True teas, black, green, white, oolong, all come from a single plant, Camellia sinensis. Rooibos does not. It is a herbal infusion, a tisane, made from the fine needles of an indigenous fynbos shrub that has been used in the Cederberg for generations before anyone thought to export it.

The plant is stubbornly local. Attempts to grow it commercially elsewhere have never produced the same cup, because rooibos depends on the specific acidic, sandy, nutrient-poor soil of that region and the harsh dry summers that come with it. That connection to place is now formally recognised. Rooibos was granted geographical indication protection in South Africa in 2014, and in 2021 it became the first African food product added to the European Union's register of protected designations of origin, alongside names like Champagne and Port. The word "rooibos" is now legally reserved for the real thing.

Why is rooibos naturally caffeine-free?

Because it never had caffeine to begin with. This is the distinction most people miss. Decaffeinated tea has had its caffeine stripped out through processing. Rooibos simply does not produce any. The plant evolved in poor soil and long droughts, and it puts its energy into surviving that rather than into producing the compounds that keep you awake.

This is why rooibos does the one thing very few good drinks can do. It works at four in the afternoon and it works at ten at night. It suits people who have given up caffeine, people who are pregnant, and households where children want what the adults are having. It is also naturally low in tannins, so it does not turn bitter and sharp the way an over-steeped black tea will.

What does rooibos actually taste like?

Good rooibos tastes rounder than most people expect. There is a soft honeyed sweetness that arrives without any sugar, a woody, faintly nutty base, and a full-bodied weight that holds up beautifully to milk if that is how you drink it.

Where it becomes genuinely interesting is in blending. Rooibos is unusually generous with other ingredients. It carries fruit, spice and floral notes without being overwhelmed by them, which is why so many of the best South African blends are built on a rooibos base.

Our own Ruby Sundara is exactly that kind of blend. Cederberg rooibos, layered with hibiscus, citrus, ginger, rose hip, blueberries, cherries, strawberries, cranberries, marigold flowers, cinnamon and vanilla, with select spices and currants sourced from Egypt adding depth. It brews a rich ruby red cup, full bodied, with notes of tart berry, gentle spice and soft sweetness. It is the pot you put on when the day is finally done and the conversation is just starting. A 30g canister is R149 and gives you roughly 10 to 15 cups.

Red or green rooibos, what is the difference?

Both come from the same shrub. The difference is oxidation, the same process that separates black tea from green.

Red rooibos, the familiar one, is bruised after harvest and left to oxidise before drying. That is what turns the green needles a deep reddish brown and develops the sweet, rounded, slightly caramel character everyone recognises.

Green rooibos skips that step. The needles are dried immediately, before they have a chance to oxidise. The result is lighter and grassier, closer in spirit to a green tea, with a delicate sweetness underneath. It is rarer and usually more expensive, simply because the processing window is less forgiving.

How do you brew loose leaf rooibos properly?

Rooibos is the most forgiving loose leaf tea you will ever brew, which makes it a good place to start if you are new to leaves rather than bags.

  • Use one heaped teaspoon of loose leaf per cup.
  • Use water at a full boil. Unlike green tea, rooibos wants the heat.
  • Steep for five to seven minutes. Longer is fine. Without the tannin load of a true tea, it deepens rather than turns bitter.
  • Strain and serve. It takes milk, honey, a slice of orange, or nothing at all.

If you want the full method, including how to get this right without a strainer, our step-by-step guide to brewing loose leaf tea covers it properly.

Why does rooibos make such a considered gift?

Because it is one of the few things you can hand someone that is unmistakably from here, and that almost nobody will refuse. It suits the person who has stopped drinking coffee, the colleague whose preferences you do not know well, the host you are thanking, the family member who has everything. There is no alcohol to navigate and no caffeine to worry about, and it arrives as something to be opened slowly rather than used up.

That is the quiet argument for loose leaf rooibos over a box of bags. One is a cupboard staple. The other is a small ritual, and rituals are what people actually remember being given.

Rooibos and Heritage Day

Heritage Day, 24 September, is the one day on the South African calendar built entirely around the question this tea already answers: what is unmistakably, defensibly ours? Rooibos has a stronger claim to that question than almost anything else in a South African cupboard. It grows nowhere else on earth, it carries protected geographical indication status the same way Champagne does, and it has been part of South African life for generations before anyone thought to bottle the story.

That makes it a considered Heritage Day gift in a way a generic hamper is not. It does not require translation or explanation. A cup of real Cederberg rooibos is the story, not a symbol of it. Our tea gift boxes are built around exactly that kind of considered giving, and if rooibos is the blend you want to lead with, Ruby Sundara remains the clearest expression of it in the range.

Frequently asked questions about rooibos

Is rooibos actually a tea?

No. Rooibos is a herbal infusion made from Aspalathus linearis, an indigenous South African fynbos shrub. True teas, black, green, white and oolong, all come from Camellia sinensis. Rooibos is often called a tea out of habit, but botanically it belongs to a different family entirely.

Does rooibos tea have caffeine?

No. Rooibos is naturally caffeine-free rather than decaffeinated, which means nothing has been stripped out of it. The plant does not produce caffeine at all, so it can be enjoyed in the evening or by anyone avoiding caffeine.

Where does real rooibos come from?

Only from South Africa, and specifically the Cederberg region of the Western Cape and its surrounding areas. Rooibos holds protected geographical indication status, so the name may only be used for tea grown in that defined production area.

Can you drink rooibos with milk?

Yes. Rooibos is full bodied enough to take milk comfortably, which is how a great many South African households drink it. It is equally good served plain, or with honey and a slice of citrus.

Rooibos has been sitting in South African kitchens for generations, usually underestimated. Brewed loose, from leaves that were grown a few hours from Cape Town, it earns a good deal more attention than that.
