ergelegen is a wine estate in Stellenbosch dating back to 1700. The name means "distantly located" in Afrikaans, and they are, indeed, on the very outskirts of Stellenbosch.
Fairview is a more recent development in the Paarl area. Their vineyards are spread in various locations in the Western Cape and hence produce an array of interestingly different wines.
They also farm goats and make a range of cheeses, quite palatable, if, somewhat unfortunately, all made from pasteurised milk.
Their wine tasting is definitely the best organised exerience of the kind I've encountered in all my travels. It is a proper sommelier-guided extravaganza where 8 wines are expertly paired with 8 cheeses. It lasts up to 2 hours, so allow at least good half a day to enjoy roaming around the estate, checking out their cheese shop and petting the goats.
My overall feeling about wine tasting in South Africa was that of a very pleasant surprise. All wines we sampled were elegantly Old World in style, nothing like the childishly fruity South African plonk we for some reason get in supermarkets in the UK and Europe. Go figure.
