There are different grades of rooibos, but not much difference between them. However, the “long cut” offers the most interesting experience in terms of fine flavours and powerful aromas. It is the most harmonious. It is the only grade I have bought for years.
An amusing detail: for rooibos tastings in South Africa, the cups are lit from beneath in order to judge the clarity of the liquor.
