South Africa-based ice-tea maker Bos has sold a fifth of the company to Invenfin, the corporate venturing unit of local conglomerate Remgro.
Manchester United football manager Sir Alex Ferguson is buying a further 10% of Bos, which makes Rooibos tea in a can.
Joe Kieser, Invenfin director, said: "What attracted Invenfin initially was the marvelous brand that Bos has developed. Backing up that distinctive brand is the excellent product itself."
