D'Aria, in Durbanville, is one of the lucky wine estates to have their own dam. Can you imagine how much water it takes to keep their grapes plump and juicy?
Incidentally, D'Aria is the home of the popular Poplars restaurant (map). I'm not huge fan of the restaurant, but many people love it, so I do think that it's worth a try at least - perhaps it's your kind of place. :)
