Barossa Valley is Australia's most celebrated wine region, built on some of the world's oldest surviving Shiraz vines and a warm, reliable climate that produces rich, full-bodied reds with real concentration. Many vineyards here were planted more than a century ago, and old-vine fruit remains central to the region's reputation for depth and power. Grenache and Mourvedre also perform well in the warmth, often blended with Shiraz into the region's take on a GSM blend. If Shiraz on its own is what you're after, Australian Shiraz covers the variety across the country's other major regions, and McLaren Vale Wine offers a useful point of comparison from South Australia's other standout area. For the wider domestic picture, Australian Wine covers every region we carry.
