What Is Rooibos Tea And What Does It Taste Like?

Rooibos tea is made from Aspalathus linearis, a shrub grown on the western coast of South Africa. The tea produces a reddish color when brewed, earning its name – red tea or red bush tea. Although rooibos tea is an herbal tea, it is not related to green and black teas.

Traditionally, rooibos tea is made by fermenting the leaves of Aspalathus linearis. The process of fermentation turns the leaves reddish-brown (1). The unfermented variety of rooibos tea is called green rooibos. It has higher antioxidant content than the red one and is more expensive.

Rooibos tea is available in plain and flavored varieties. Red rooibos tea has a smooth, fruity-sweet, earthy flavor and can be consumed as a hot or cold beverage. The unfermented rooibos tea has a slightly astringent flavor. Overall, it is milder than black and green teas.

Rooibos tea is graded based on many factors like color, flavor, and cut length. The highest grade of rooibos tea is called the ‘super grade.’ Due to its mild taste, rooibos tea is often added to multi-blend herbal tea concoctions. It is also rich in several different antioxidants, such as flavonoidsi  XPowerful antioxidants that protect the body against everyday toxins and stressors and help it function effectively. . Let’s take a look at the major flavonoids in this tea.
