Australia's McLaren Vale, south of Adelaide, enjoys a Mediterranean climate thanks to proximity to the ocean, with warm, dry summers and most of its precipitation concentrated in the winter months. With irrigation necessary but water scarce, the best wines come from low-yielding old vines with deep roots. McLaren Vale is best known for its fleshy, full-flavored Shirazes and Cabernets, but Grenache is on the upswing and there is also a good bit of mostly low-acid Chardonnay.
