As the world's fifth largest producer of wine, after France, Italy, Spain and the United States, Argentina has plenty to offer the international wine market in regards to both quantity and quality. Despite this being the case for several decades now, it has only been since the end of the twentieth century that the Argentinian wine industry has really begun to up their game when it comes to the methods and techniques required to produce world class wines, which are both representative of their country and region of origin, and which stand alone as complex, interesting and delicious wines to drink. As Argentina became a serious contender in the international wine market, wineries previously concerned primarily with high volumes began to change their priorities, and formerly struggling small bodegas and independent wineries began to find success. Nowadays, well crafted wines from smaller vineyards in Argentina are being lauded as some of the finest in the world, and the country is starting to reap the benefits of its heritage, which include some very old vines, and up to four centuries of experience in wine production. 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.
