A farmworker mixes piles of raw Rooibos tea as it emerges from a thresher at a processing plant in the remote mountains of the Cedarberg region, about 300km (186 miles) north of Cape Town, March 30, 2006. South African suppliers say the tea, grown nowhere else, is poised for a big expansion in the U.S. market following their victory in a trademark dispute in American courts last year.
