The vast region of South Australia is home to a wide variety of vineyards, growing a large range of different grape varietals. Because the South Australian wine region is so large, it benefits from a great array of climatic conditions – from dry and hot, to cool and windy – which wineries can use to their advantage when it comes to selecting the grape varietal they wish to thrive in a particular sub-region. South Australia is most commonly associated with the big, powerful and fruit-forward Shiraz wines which are produced in the cooler valley areas of the region, but recent decades have seen something of an explosion in the South Australian wine industry, leading to wineries expanding their repertoire enormously and experimenting with other fine grape varietals and making the most of their unique terroir.
The most important grape of the Northern Rhone Valley, Syrah is quickly becoming one of the most noted grapes planted in America. America's best bottlings hail from the Central Coast, Santa Barbara, Sonoma County and Napa Valley. Syrah displays a spicy blend of black pepper and raspberries, with dark fruit undertones; full-bodied with smoke, tar and tannins. It is made into a few magnificent varietally labeled wines, but is also often the base grape for Rhone-style blends. There are those who believe that the Napa Valley should be planted mostly to Syrah, for it thrives in warm growing regions. In Australia, where it is the most-planted red variety, and in South Africa, the grape is known as Shiraz. While viticulturally identical with Syrah, Shiraz grown in Australia is typically sweeter and riper, with more chocolately notes than pepper and spices.
