July 14, 2022

Black tea is one of the most widely consumed beverages in the world. From the longstanding tradition of afternoon tea in the British Isles to the milky spiced beverage known as masala chaiin India, black tea has long been celebrated by many cultures around the globe.

Rooibos tea, also known as red bush tea or red tea, is not as widely known as black tea
though that may be changing, as it is quickly becoming a favorite among many tea drinkers.

But tea enthusiasts who are new to drinking rooibos often wonder: is rooibos tea a black tea? If
not, what is the difference between black tea and rooibos? Keep reading to learn everything you
should know about this flavorful redhued beverage and how it differs from black tea.

Rooibos Tea Vs. Black Tea Origins

The major difference between black tea and rooibos is that they are harvested from two entirely
different plants, which are native to different parts of the planet.

Black tea is derived from the traditional tea plant Camellia sinensis, which is native to East Asia
and the Indian Subcontinent. This is the same plant used to produce
green tea, white tea and
puerh tea
. India is the world’s largest producer of black teas, though it is also cultivated in
China, Sri Lanka, Indonesia, Nepal, Kenya and elsewhere around the world.

Rooibos, on the other hand, is derived from the shrub Aspalathus linearis, which grows in the
Western Cape of South Africa. After the leaves are harvested, they undergo oxidation the
process that gives rooibos leaves their distinctive reddishbrown color. Red bush tea has been
consumed in South Africa for hundreds (if not thousands) of years, though it has only gained
popularity in Western cultures during the last several decades.

Rooibos Tea Vs. Black Tea Caffeine

Camellia sinensis naturally contains caffeine, though the amount of caffeine varies depending
on how the leaves are processed after harvest. In the production of black tea, the Camellia
sinensis leaves are allowed to fully oxidize before they are heated and dried. This causes them
to retain more caffeine than other varieties, such as green tea. A standard sixounce cup of
black tea contains approximately 50 milligrams of caffeine, or around half the amount found in a
similarlysized cup of coffee.

Does rooibos tea have caffeine? Rooibos is an herbal tea, which means it is naturally caffeine
free. This makes rooibos a wonderful choice for sipping at any time of the day or evening, as
well as for tea drinkers who are sensitive to the effects of caffeine.

Rooibos Tea Vs. Black Tea Taste

Generally speaking, black tea has a bold, slightly malty flavor and a strong aroma. The flavor of
black tea leaves changes and develops during the oxidation process, resulting in a deeper, full
bodied taste compared to other tea varieties. Various combinations of sugar, honey, lemon and
milk or cream are commonly added to black tea.

Depending on where in the world it is grown and how exactly it is processed after harvesting,
black tea’s tasting notes might be described as nutty, smoky, spicy, earthy, fruity, leather,
caramel, citrus, or honey. Popular varieties of black tea include Assam, Darjeeling and Ceylon.
Each offers its own unique tasting experience.

What does rooibos tea taste like? Red tea is smooth and easy on the palate, with a fullbodied
nutty, woody flavor and natural sweetness. The flavor of rooibos lends itself well to herbal
blends, especially those featuring warm notes of vanilla, caramel and chocolate, as well as
citrus and other fruit flavors.

Like black tea, rooibos is often served with milk, lemon, sugar or honey. Rooibos tea lattes are a
favorite among tea drinkers who desire a satisfying warm beverage without the caffeine.

Rooibos Tea Vs. Black Tea Health Benefits

There are numerous benefits of drinking black tea. As previously mentioned, black tea contains
just half the caffeine of coffee. In the right dosage, caffeine can have a positive effect on mood,
concentration and exercise performance.* But for individuals who are sensitive to the effects of
switching from coffee to tea in the mornings can help reduce unwanted side effects
such as shakiness, dizziness, insomnia and stomach upset.*

During the process of oxidation, black tea leaves develop flavonoids beneficial plant
compounds with antioxidant properties. Antioxidants may help remove free radicals from the
body and decrease cell damage, which is a major cause of many chronic diseases.*
studies have found that the antioxidants in black tea may lower the risk of certain
cancers, heart disease and diabetes.*

What are the health benefits of rooibos tea? Like black tea, red bush tea is rich in antioxidants
that may help the body fight off disease and cellular damage over time.* In particular, the
antioxidants found in rooibos tea have been linked to increased heart health.*

Yet unlike black tea, rooibos is low in tannins and contains no oxalic acid, making it a gentler
alternative for individuals with gut sensitivities or who are prone to kidney stones.* Rooibos also
contains iron, magnesium, phosphorus, potassium and other nutrients.*

How About Green Rooibos vs. Green Tea?

Another common source of confusion among tea drinkers is green rooibos tea. Given the name,
it might be easy to assume that green rooibos is rooibos tea blended with green tea however,
that is not the case.

Green rooibos is made from the same plant as red rooibos, Aspalathus linearis. But like green
tea, green rooibos undergoes a heating process that halts oxidation. This process affects the
chemical structure of the leaf, as well as the final color and flavor.

Compared to red rooibos, green rooibos is lighter and mellower in flavor, but with the same
natural sweetness and nutty taste. It is also entirely caffeinefree and offers many of the same
wellness benefits as red rooibos.*
