The Rhone Valley of southern France is a particularly fascinating wine region, with a history that stretches back to at least six hundred BCE, when the ancient Greeks first began cultivating vines there. The region itself is split into two distinct sub-regions, with the northern sub-region being famed for its production of exceptional Syrah, Marsanne, Roussane and Viognier wines, packed full of interesting character and expressing the terroir found there. The southern sub-region is home to an enormous variety of grapes, and produces red, white and rosé wines, and some of the world's most famous and adored blended wines. The continental climate of the region is ideal for growing grapes, and the winds which blow from the Central Massif help temper the heat in the vineyards, leading to very ripe fruits holding plenty of flavor. 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.
