In South Africa it is more common to drink rooibos with milk and sugar, but elsewhere it is usually served without. The flavour of rooibos tea is often described as being sweet (without sugar added) and slightly nutty. Rooibos can be prepared in the same manner as black tea, and this is the most common method. Unlike black tea, however, rooibos does not become bitter when steeped for a long time; some households leave the tea to steep for days at a time. Rooibos tea is a reddish brown colour, explaining why rooibos is sometimes referred to as "red tea". Unlike some higher quality oolong or green teas, rooibos is often only good for a very limited re-steeping as there is a sharp drop off in brewing after the first infusion.
