Impressive as these staunch reds are, it's the lighter lunchtime wine, Steingarten riesling, I love the most because it's perfect for drinking in the sun with our fresh fish. The name of the wine comes from the stony ("stein") sliver of hillside on which the vines are grown (hence "garten").
The Barossa Valley's best restaurants and cafes tend to be far flung from each other and Jacob's Creek is more than merely a reliable dining destination. It serves food outstanding for its freshness, purity of flavour and beautiful presentation.
After lunch we meander back to the Art Deco Richmond Hotel, tucked away in a narrow alleyway-cum-corridor off the bustling Rundle Mall in the CBD. It's an unlikely location for top accommodation, but our room is large, silent and haven-like with its marble bathroom, king-size bed, sofa and 24/7 free movies.
It's also within walking distance of the best shopping and the outstanding weekend markets in Gouger St. It is there we brunch, lunch and shop for dinner ingredients the following day. The city actually feels like a welcome break after a week of visiting wineries in the Adelaide Hills, an hour's drive south.
The Hills are home to a string of quaint Germanic-style towns, whose architecture echoes the roots of early settlers with high-pitched roofs, ancient-looking stone buildings and wide tree-lined streets. Hahndorf is the prettiest of these towns. It's set on each side of a wide main street and is home to beautifully restored stonebrick buildings, some mouth-watering delicatessens and The Manna, a fresh new motor lodge with a spa and self-contained accommodation.
One of the most interesting places to eat in the Adelaide Hills is in the modern town of Stirling.
Here, we explore and enjoy the concept of local food which adheres to the 100-mile concept - all produce must come from within a 60km radius. It is part of a worldwide food movement with a philosophy to make a "collaborative effort to build more locally based, self-reliant food economies", we are told on our menus, while enjoying some of the best Australian pinot noirs I've ever tried, from Ashton Hills.
Direct flights are now available to Adelaide, making the hub of the Australian wine industry easily accessible.

Modern buildings are rare in this little slice of German settler-ville, in the Adelaide Hills, but the Manna breaks the mould with its unobtrusive, modern, self-contained accommodation on the main street. It slots right in behind the small courtyard fountain, and is quiet and extremely comfortable.
