ahhhh, that's my back yard :P ..... the stivo spent plenty fo it's 1st 10,000 km's on those roads... :) Wirra Wirra is a nice one, d'Arenberg is also good, Colriole is worth a visit as they have some great olive oils and cheeses to top of the wine tasting :) , Fox Creek is great, Pirramimma is lovely as you still go into the cellar for the cellar door sales, adds some old-world charm to the experience and wines are nice to boot. Hugo is OK, but not fantastic... I would avoid Tattachilla and Woodstock (though the Stocks Shiraz is good) I can't think of the others off the top of my head but I know there are many more...
