Riesling grapes have been grown in and around central Europe for centuries, and over time, they became the lasting symbol of south Germany's ancient and proud wine culture. Whilst the reputation of German wines abroad has in the past been mixed, the Germans themselves take an enormous amount of pride in their wineries, and Riesling grapes have now spread around the globe, growing anywhere with the correct climate in which they can thrive. Riesling grape varietals generally require much cooler climatic conditions than many other white grapes, and they are generally considered to be a very 'terroir expressive' varietal, meaning that the features and characteristics of the terroir they are grown on comes across in the flavors and aromas in the bottle. It is this important feature which has allowed Riesling wines to be elevated into the category of 'fine' white wines, as the features of the top quality bottles are generally considered to be highly unique and offer much to interest wine enthusiasts. 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.
