Try these, probably the best in SA. @Spizz they have Mr Brownstone at the H&A Brewery.
Most of the beers at The Hart in Melkbosstrand is from there, so you likely had some when you were there.
I went to that Woodstock Brewery for a MyBB meet. Nice place although I can't remember what I was drinking. I'm currently enamoured with the Saggy Stone range though. The Rocky River Pale Ale is pretty fab.
