In this piece, we delve deep into all the rooibos tea benefits so you can see exactly what this brew can do for you. From being beautifully caffeine-free (farewell coffee crash) to boosting your heart health, here’s all the science you need to get sipping this young and bright tea that is already taking the world by storm.


What is Rooibos Tea?

Rooibos tea is a herbal tea that comes from the Fabaceae plant family. This plant grows in South Africa and the leaves are taken and fermented to be turned into tea. Rooibos tea means ‘red bush’ and the tea is also sometimes called bush tea, red tea, or red bush tea.

Rooibos is part of a unique crop of flora found in an area of South Africa that sits north of Cape Town. The Cederberg Mountains. This landscape is famed for its ancient rock art and impressive sandstone formations and it’s here amidst all that history that the humble rooibos plant sprouts its leaves.

While this plant is still young compared to the Camellia Sinensis plant that has been flourishing for thousands of years, rooibos has earned quite the reputation in a relatively short span of years. It has been grown and brewed by farmers and bush people for hundreds of years and recently the world has taken notice. Rooibos is only found in South Africa naturally but it exports around seven thousand tons of leaves every year, with shipments heading to over thirty countries around the world, everywhere from Japan to Germany and the USA.

The rooibos plant has long needle leaves and is harvested in a similar way to the black tea plant. During harvest time the stems and leaves are cut and bound together into bundles which are to be oxidized. Oxidation is what helps the tea get that delicious deep red coloring and the redder it gets, the richer and sweeter the taste of the tea becomes. While this is how you make the red bush version of the tea, there is also green rooibos which is similar to green tea. Just like green tea, it’s the oxidation process that is different.

Rooibos is loved for its taste and the fact that it makes a great alternative to those more caffeine-centric teas. As Rooibos is herbal, it also brings a bounty of health benefits to the table too. The taste of rooibos is earthy, slightly sweet, and swirled with the taste of nuts, caramel, and an almost smoky vanilla fragrance too. You can sip your rooibos with a spoon of honey for sweetness, a slice of lemon to cut through the smoke, or even with a dash of milk if you want more of that creaminess and to temper the reddish hue.
