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. The sparkling wines of Champagne have been revered by wine drinkers for hundreds of years, and even today they maintain their reputation for excellence of flavor and character, and are consistently associated with quality, decadence, and a cause for celebration. Their unique characteristics are partly due to the careful blending of a small number of selected grape varietals, most commonly Chardonnay and Pinot Noir. These grapes, blended in fairly equal quantities, give the wines of Champagne their wonderful flavors and aromas, with the Pinot Noir offering length and backbone, and the Chardonnay varietal giving its acidity and dry, biscuity nature. It isn't unusual to sometimes see Champagne labeled as 'blanc de blanc', meaning it is made using only Chardonnay varietal grapes, or 'blanc de noir', which is made solely with Pinot Noir.
