Wondering whether rooibos is a tea or an herbal infusion? It's a question that comes up often, and for good reason: this red drink from South Africa has a habit of causing confusion in the cup. Sometimes called "red tea," rooibos actually has nothing to do with the traditional tea plant. Let's take a closer look at what really lies behind this remarkable infusion, and why it deserves a place in your everyday routine.

The essentials in 30 seconds

• Rooibos is not a tea: it's an infusion made from a South African shrub, not from the tea plant
• Zero caffeine, zero theine: perfect for the whole family, even in the evening
• Rich in antioxidants: well-documented benefits for digestion and sleep
• Naturally smooth flavour: delicious plain or flavoured, hot or iced
• One-of-a-kind origin: grown exclusively in the mountains of the Western Cape, South Africa

So, tea or herbal infusion? The answer might surprise you

Strictly speaking, rooibos is neither a tea nor an herbal infusion in the traditional sense. Which only adds to the intrigue.

For a drink to be classed as a tea, it must come from the leaves of the tea plant (Camellia sinensis). Rooibos, however, comes from an entirely different shrub: Aspalathus linearis, a member of the legume family. Despite the common nickname "red tea," calling it a tea is technically a misnomer.

As for herbal infusions, these traditionally refer to drinks made from medicinal or aromatic plants such as chamomile, verbena or mint. Rooibos, with its distinctive properties and uniquely specific origin, sits in a category of its own.

In practice, rooibos belongs to the broad family of infusions, a general term covering any drink made by steeping plant material in hot water. This is indeed how professionals classify it today.

A shrub like no other, exclusively South African

What makes rooibos so singular is its remarkably limited geographical range. This shrub grows naturally only in a small mountainous region north of Cape Town, South Africa. Every attempt to cultivate it elsewhere in the world has failed.

Aspalathus linearis resembles a spiny bush, growing up to 1.5 metres tall. Its fine, needle-like leaves give it a distinctive appearance. In spring, it becomes covered in tiny, delicate yellow flowers, each of which will produce a single seed.

There are two main varieties:

• Red rooibos: the most familiar, produced through natural fermentation
• Green rooibos: unfermented, with fresher, more vegetal and fruity notes

This geographical exclusivity is partly why rooibos remained relatively unknown until the 1990s, before going on to win over the rest of the world.

From harvest to your cup: a time-honoured craft

The transformation of rooibos follows a fascinating process, passed down through generations by local communities.

Harvesting takes place during the Southern Hemisphere summer (January to March). The plants are cut with a sickle, and the leaves and stems are finely chopped.

Oxidation is the key stage: the chopped leaves are moistened and arranged in small heaps in the open air. Over 12 to 18 hours, they ferment naturally, turning from green to the characteristic deep red. It is this fermentation that develops rooibos's smooth flavour and its warm, vanilla-tinged aroma.

Final drying takes place under the South African sun. The leaves are spread out over large surfaces until they reach the ideal moisture content (around 11%). They are then sifted to remove impurities, steam-treated, and packaged.

For green rooibos, the fermentation step is skipped entirely: the leaves are dried immediately, preserving their colour and their fresher, lighter character.

The benefits that set it apart

What truly distinguishes rooibos from other infusions is its exceptional properties. Unlike tea, it contains no theine or caffeine, making it an ideal drink at any hour of the day.

Rich in antioxidants, rooibos contains aspalathin and quercetin, compounds that help protect against cellular ageing. These antioxidants are actually more stable than those found in green tea.

Gentle on digestion, it soothes intestinal discomfort and can help ease colic in infants. Its low tannin content makes it very kind to the stomach.

A natural sleep companion, drinking it in the evening carries no risk of keeping you awake. On the contrary, its relaxing properties can help ease you into sleep.

A source of minerals, it provides iron, potassium, calcium and magnesium, without any of the downsides of caffeine. This is why it is especially recommended for pregnant women, children and those who are sensitive to stimulants.

How to enjoy it to the fullest

One of rooibos's great appeals is how easy it is to prepare. Unlike tea, which calls for careful attention to temperature and steeping time, rooibos is wonderfully forgiving.

Classic preparation: pour near-boiling water (95°C / 200°F) over a teaspoon of rooibos and leave to steep for 5 to 7 minutes. The longer you steep it, the more its aromas develop, without ever turning bitter.

Plain or flavoured? On its own, rooibos reveals soft, gently sweet notes with hints of vanilla and honey. It also pairs beautifully with spices (cinnamon, cardamom), fruit (orange, apple) or flowers (rose, jasmine).

Hot or iced, it adapts to your mood. In summer, try it cold with a few fresh mint leaves and a slice of lemon.

With or without milk? Unlike tea, rooibos pairs perfectly with milk, creating a creamy, comforting drink that children love.

Questions we're asked most often

Can rooibos replace tea?

Absolutely. If you're looking to cut down on caffeine or if you find tannins hard on your system, rooibos makes an excellent alternative. Its antioxidant richness and naturally smooth flavour make it a great substitute, particularly for evening drinks.

How many cups of rooibos can you drink a day?

Good news: there's no limit. Unlike tea or coffee, rooibos contains no stimulants. You can drink as much as you like, and so can children and pregnant women. Some people enjoy up to six cups a day without any issue.

Does rooibos help with weight loss?

Rooibos won't cause weight loss on its own, but it can support a balanced approach to wellness. Calorie-free when drunk plain, rich in antioxidants and gentle on digestion, it's a wholesome drink that can easily replace sodas or sugary beverages.

Can you give rooibos to babies?

Yes, in moderation and from six months onwards. Rooibos has long been used in South Africa to soothe infant colic. That said, always consult your paediatrician before introducing any new drink into your baby's diet.

Is organic rooibos better?

Organic rooibos guarantees cultivation without pesticides or chemical fertilisers, which is always a positive. That said, the rooibos-growing region is naturally well-preserved, and even conventional rooibos tends to be of good quality. The choice comes down to your own values and budget.

How should rooibos be stored?

Like all infusions, rooibos keeps best in a dry place, away from light and strong odours. An airtight tin or caddy works perfectly. Stored well, it retains its properties for two to three years, though its aromas may gently fade over time.
