Rooibos (the word is Afrikaans for “red bush”) is only grown in a small area in the Cederberg region of the Western Cape province of South Africa. It contains no caffeine, and provides plenty of health benefits that have made it a very popular alternative to tea in recent years. Packed with vitamins, minerals, and anti-oxidants, it is a natural and healthy choice. Rooibos brews up a naturally sweet, dark red infusion. Some say it has a slightly nutty flavor.
