The Simple, Scientific Answer: No, Rooibos is Caffeine-Free
Many tea lovers seeking a calming evening beverage or looking to reduce caffeine intake often ask, "Did rooibos tea have caffeine?" The answer is no. Rooibos tea is an herbal infusion, or tisane, which is distinct from 'true' teas like black, green, oolong, and white, all of which are derived from the Camellia sinensis plant. The Aspalathus linearis shrub, from which rooibos is harvested, contains no caffeine in its natural genetic makeup. This makes rooibos inherently caffeine-free, without needing processing to remove the stimulant.
The Difference Between True Teas and Herbal Infusions
The confusion about rooibos often stems from its common name, 'red tea,' which can lead people to group it with caffeinated black or green teas. However, the term 'tea' refers to how it is brewed rather than its botanical origin. This distinction is crucial for anyone managing caffeine consumption. For instance, while green tea contains caffeine, green rooibos (an unfermented version of the rooibos plant) remains entirely caffeine-free.
Health Benefits of a Caffeine-Free Brew
Besides being a caffeine-free alternative, rooibos tea is celebrated for a host of health benefits, making it an excellent addition to a wellness-focused diet. Its lack of caffeine and low tannin levels are major advantages, especially for those sensitive to stimulants or prone to iron deficiency.
Here is a list of potential health benefits associated with drinking rooibos tea:
- Rich in Unique Antioxidants: Rooibos contains antioxidants such as aspalathin and nothofagin, which help protect the body from free radical damage and reduce oxidative stress.
- Supports Heart Health: Studies suggest that compounds in rooibos may help improve cholesterol levels and lower blood pressure, contributing to cardiovascular wellness.
- Aids Digestion: The tea has antispasmodic properties that can help soothe stomach cramps, bloating, and indigestion.
- Enhances Sleep Quality: As a non-stimulant, rooibos can promote relaxation and is a great choice for a calming bedtime ritual.
- Low in Tannins: Unlike black tea, rooibos has low tannin levels, which means less bitterness and minimal interference with iron absorption.
- Promotes Healthy Skin: Some of the compounds in rooibos, including zinc and alpha-hydroxy acids, are beneficial for skin health, potentially helping with acne and signs of aging.

Brewing the perfect cup of rooibos is simple and flexible. Unlike caffeinated teas, it is very forgiving to the brewing process and will not turn bitter if over-steeped. This allows for a robust and flavorful brew. To get the most from your rooibos, follow these steps:
- Boil fresh water, ideally to 100°C (212°F).
