Rooibos Tea

What Is Rooibos Tea Made From?

Rooibos is made from the rooibos tea plant, Aspalathus linearis, a shrub in the Fabaceae, or legume, family. It grows in South Africa, mainly in the Cederberg area of the Western Cape, part of the wider Cape Floristic Region. This is one of the few places on earth where the plant thrives properly, which gives rooibos a strong sense of place.

The plant itself has fine, needle-like leaves and can grow to around three feet in height. It survives in demanding conditions, with cold winters, very hot summers, and dry, rugged ground. Those conditions help shape the crop and are one reason rooibos remains closely linked with its home region.

Once harvested, the leaves and stems are cut and processed. If they are bruised and left to oxidise, the result is the familiar reddish-brown version often called red rooibos or fermented rooibos.

If oxidation is stopped early, the result is green rooibos, also called unfermented rooibos. In strict technical terms, oxidation is not the same as fermentation, but “fermented rooibos” is still widely used in the tea trade.

Unlike tea from Camellia sinensis, rooibos is an herbal infusion. That matters because it changes both the flavour profile and the chemistry of the cup. Rooibos is naturally free from caffeine and tends to be lower in tannins than black or green tea, which helps explain its soft, easy-drinking nature.

History of Rooibos Tea

Deeply rooted in South African history. Long before it became known abroad, Indigenous Khoisan communities used the plant as a drink and valued it as part of daily life. Much of that early history was passed down through practice rather than a formal written record, which is common among many traditional foods and drinks.

European awareness came later. The botanist Carl Thunberg is often linked with the plant’s wider documentation in the eighteenth century, and commercial interest grew much later still. In the early twentieth century, the tea merchant Benjamin Ginsberg helped bring rooibos to a broader market, presenting it as a South African herbal alternative to black tea.

Its popularity, particularly for rooibos tea in the UK, rose at different points during tea shortages and shifts in consumer taste. Over time, rooibos tea built a place for itself not only because of its origin story, but because it was pleasant to drink and suited people looking for an option without caffeine.

Historical claims around wellness, including stories linked to colic and allergies, sparked public interest. Though those claims should be treated as part of its cultural history rather than settled medical fact.

Red Rooibos vs Green Rooibos Tea

Red rooibos is the variety most people encounter first. It brews to a warm mahogany colour and offers a rounded sweetness with a mellow body, making it ideal for both plain drinking and flavoured blends. In contrast, Rooibos Green Tea is less common but steadily gaining popularity, especially among those who prefer a lighter, fresher cup.

The main difference between the two lies in their processing. Red rooibos is oxidised after picking, which gives it its characteristic deep red to reddish-brown colour and sweet, nutty flavour with gentle caramel notes. This makes it perfect for everyday drinking, pairing well with milk or as a base for flavoured blends.

Green rooibos, on the other hand, is heated or dried in a way that limits oxidation. As a result, it produces a pale golden to light amber infusion with a fresher, grassier, and slightly sharper taste. Green rooibos is best enjoyed brewed plain, with a slice of lemon, or served as a refreshing iced tea.

If you’re new to rooibos and want to learn how to drink rooibos tea, red rooibos or redbush tea is usually the easiest place to start. Once you’ve developed a taste for the plant’s unique character, green rooibos offers a brighter, more vibrant expression to explore.

What Does Rooibos Tea Taste Like?

Rooibos tastes naturally soft and rounded. Red rooibos often has notes of honey, nuts, wood and light caramel, with a mild sweetness that needs no sugar for many drinkers. It does not have the brisk edge of black tea or the grassy lift of Japanese green tea, so the experience is gentler from the first sip.

Green rooibos is lighter and slightly more plant-like. Some people find it cleaner and crisper, while others prefer the comfort of the red style. Flavoured versions, including vanilla, caramel, orange or spiced blends, build on the base tea rather than hiding it, which is why rooibos works so well in blends.

Common flavour notes include

• Honeyed sweetness
• Gentle nuttiness
• Soft woody warmth
• Light caramel tones
• A clean, mellow finish

One reason rooibos appeals to so many people is that it is very forgiving. Even when brewed quite strongly, it rarely turns harsh in the way over-steeped black tea can.

Does Rooibos Tea Have Caffeine?

Plain rooibos is naturally caffeine free. That is one of its biggest selling points and a major reason for its popularity in the evening or late afternoon. If you want a warm drink before bed, or you are trying to cut back on coffee and standard tea, rooibos is a practical choice.

It is also worth keeping one detail in mind. Rooibos is caffeine free unless it has been blended with a caffeinated tea ingredient, usually black tea, green tea or matcha. So if the packet says chai rooibos, breakfast rooibos, or something similar, the ingredient list is always worth checking.

Because it contains no caffeine, rooibos does not give the lift that many people expect from breakfast tea or coffee. That can be a drawback in the morning if you want stimulation, but a benefit at other times of day. Many drinkers keep both on hand: one drink for energy, one for comfort.

Is Rooibos Tea Good for You?

Rooibos has built a strong reputation as a healthy drink within tea culture, and some parts of that reputation are well supported. It is naturally caffeine free, low in tannins, and very low in calories when drunk plain. It also contains plant compounds known as polyphenols, including aspalathin, which is often highlighted in rooibos research.

The more difficult question is how much those compounds change health outcomes in real life. Human research exists, but it is still fairly limited. A 2023 scoping review looked at 18 publications involving 488 participants and reported early signs that rooibos consumption may be linked with improved lipid profiles, stronger antioxidant status, and lower blood glucose in healthy and at-risk groups. That is promising, but it is still a small evidence base.

This means rooibos can be sensibly described as a healthy drink choice, but not as a cure or treatment. It may fit well into a balanced diet, especially if it replaces sugary drinks or late-day caffeinated drinks. It should not be sold as a miracle answer for heart issues, skin problems, weight loss or allergies, even though those claims often appear in older articles and marketing language.

A practical way to look at it is this

• What is well established: Rooibos is naturally caffeine free and low in tannins.
• What it contains: Polyphenols, including aspalathin, plus small amounts of minerals.
• What early human studies suggest: Possible benefits for antioxidant status, blood lipids and blood glucose.
• What remains uncertain: Larger and better controlled human trials are still needed.

That still leaves rooibos in a good place. A warm drink that is pleasant, low in calories, and easy to enjoy without sugar already has a lot going for it.

How to Make Rooibos Redbush Tea

Brewing rooibos is refreshingly simple. It works well as loose leaf tea and as rooibos tea bags, and it does not need delicate handling. In fact, this is one of the reasons it suits both long-time tea drinkers and people who just want a dependable cup without fuss.

For the best result, use fresh water brought close to the boil, around 95°C to 100°C. Loose rooibos usually needs about one teaspoon per cup. Because it is low in tannins, it can handle a slightly longer steep without becoming too sharp, which gives you room to adjust the strength to your taste.

A simple method is

1. Add about one teaspoon of loose rooibos per cup to an infuser or filter.
2. Place it in your cup or teapot.
3. Pour over freshly boiled water.
4. Leave to steep for 5 to 7 minutes.
5. Remove the leaves and serve.

If you like a fuller cup, a slightly longer steep can work well. Many people enjoy redbush tea plain, but it also takes honey, lemon and milk surprisingly well. Red rooibos is often the better option with milk, while green rooibos is usually nicest on its own or with a slice of lemon.

Rooibos also makes a very good iced tea. Brew it a touch stronger than usual, chill it, then pour over ice. Citrus, berries and a little honey all pair nicely with its natural sweetness.

Store it in an airtight container away from heat, light and moisture, and it should hold its character well.

For anyone wanting an easy herbal infusion with a genuine sense of origin, a naturally caffeine-free profile, and a flavour that works across seasons, rooibos is an easy one to keep coming back to.
