Redbush Tea/Rooibos

Last time I went downtown to run errands, I stopped by one of the local cafés, in fact the café of a church (I kid you not). Not that I want to convert, but they serve really cheap food and drinks and service is just as good as in the big chains. I ordered rooibos, which baffled the young person at the till. They have it as redbush on the menu. I prefer the South African term. I hadn't had rooibos in ages and I had forgotten how nice and relaxing it was. I think I will make it a regular thing, when I want a hot drink in the afternoon but cannot have black tea. And you, dear readers, do you drink rooibos? How do you call it?
