Whilst most of Australia consists of arid deserts and dense bushland, the oceanic coasts to the south of the country have a terrain and climate ideal for vine cultivation and wine production. It took several decades of failed attempts at the end of the 18th century in order to produce vines of a decent enough quality for making wine, but since those first false starts, the Australian wine industry has continued to grow and grow. Today, wine production makes up for a considerable part of the Australian economy, with exports in recent years reaching unprecedented levels and even overtaking France for the first time ever. Whilst the greatest successes in regards to quality have been the result of the Syrah grape varietal (known locally as Shiraz), Australia utilizes several Old World grapes, and has had fantastic results from Cabernet Sauvignon, Merlot, Riesling, Chardonnay and more. As the Australian passion for locally produced wine continues to develop, wineries have begun experimenting with a wider range of grape varietals, meaning that nowadays it isn't uncommon to find high quality Australian wines made from Petit Verdot, Sangiovese, Tempranillo and Viognier, amongst many others. Although primarily associated with the Rhone region of France, the precise origins of the Viognier grape variety are unknown, and the subject of much debate. However, these fine and delicate green skinned grapes are an important varietal for many of France's most elegant white wines, and they are quickly beginning to spread around the New World, too, where wineries are discovering their unique qualities and unusual character. Viognier grapes are notoriously difficult to grow, due to the fact they are highly susceptible to mildew, but wineries persevere with them nonetheless, producing wines which are highly aromatic and have a great, fruit-forward character. Their delicate aroma suggests sweetness due to its flowery, sappy nature, but the wine itself generally very dry and crisp, and full of summery, light and refined qualities.
