Distell has been ordered to change the advertising, packaging and website for its Two Oceans wine brand after advertising authorities ruled that it was misleading consumers.
South Africa's Advertising Standards Authority (ASA) made the ruling following a complaint from rival wine producer Cape Point Vineyards.
Distell may appeal, it said today (15 December).
Cape Point complained that the Two Oceans packaging, advertising and website implied that the wine was sourced from the Cape Point area.
Grapes for Two Oceans are sourced from across the Western Cape and the wine is produced in Stellenbosch.
The ASA upheld the complaint, calling Distell's communication "at best ambiguous".
Distell told just-drinks that it never intended to mislead consumers.
It called the ruling "unfortunate", but added that it is confident the matter can be resolved with "small adjustments" to the label, advertising and website.
