Apparently Jan van Riebeeck planted the first two cultivated olive trees at the Cape on his farm Boschheuvel in 1661. Then In 1907 a farmer from Paarl received a gold medal for the ‘finest olive oil produced in the British Empire’ at the London Show. I discovered this at a lovely website called Olives Go Wild.
There are a number of producers in the Western Cape – one of whom took top honours in an international competition in 2009. The following quote from an article on the site MediaClubSouthAfrica.com by Janine Erasmus sums it up:
“South African olive oil producer Willow Creek Olive Estate has taken top honours in the prestigious L’Orciolo d’Oro olive oil competition in Gradara, Italy – the world’s second biggest producer of olive oil. The competition took place at the end of June 2009. Willow Creek’s flagship Directors’ Reserve extra virgin olive oil won the intensely fruity category at this year’s competition, edging out the second- and third-placed Spanish oils that were its closest rivals.”
