Shiraz, with which it is often blended. It can be found in several wine regions, with many large producers using grapes from several states. Notable regional differences characterize Australian Cabernet Sauvignon: in addition to the wine styles of Coonawarra and Margaret River, the Barossa Valley produces big, full-bodied wines while the nearby, cooler Clare Valley produces wines with more concentrated fruit, and wines of the Victorian wine region of the Yarra Valley are noted for their balance in acidity, tannins and fruit flavours. Other New World producers Since the end of apartheid, the South African wine industry has been working to reestablish itself in the world's wine markets, with many regions actively promoting their Cabernet Sauvignon. Today it is the most widely planted red wine grape in South Africa. It is produced in varietal and blended styles; some producers favour a Bordeaux blend, while others follow the Australian example of blending with Syrah. Early examples of South African Cabernet Sauvignon were produced by grapes planted in vineyard locations that were cooler than ideal, creating very herbaceous wines with the distinctive "green bell pepper" notes. In the mid-1990s, there was more emphasis on harvesting at fuller ripeness, and new clones were introduced that produced riper, sweeter fruit. As the vines age and better vineyards locations are identified, regional styles are starting to emerge among South African Cabernet Sauvignons: the Stellenbosch region is noted for heavy, full-bodied wines while Constantia's wines are characterized by their herbal and minty flavours. In New Zealand, the climate has been a challenge in finding wine regions suitable for producing Cabernet Sauvignon. Most of the industry focus has centred on the North Island. The Hawkes Bay region was the first to make a significant effort in producing Cabernet Sauvignon, but the region's cool climate, coupled with the high yields and fertile alluvial soils, produced wines that were still marked with aggressive green and vegetal flavours. Added focus on canopy management, which gives the grapes more sunlight to ripen by removing excess foliage, and low vigour rootstock and pruning combine to achieve lower yields and have started to produce better results. The grape is sometimes blended with Merlot to help compensate for climate and terroir. Other regions in New Zealand have sprung up with a renewed focus on producing distinctive New Zealand Cabernet Sauvignon: The Gimblett Road and Havelock North regions of Hawkes Bay, with their warm gravel
