The beautiful state of Oregon has, over the past few decades, become increasingly well known and respected for its wine industry, with several small but significant wineries within the state receiving world wide attention for the quality of their produce. Whilst the first vineyards within Oregon were planted in the 1840s, the state's wine industry didn't really take off until the 1960s, when several wine producers from California discovered that the cooler regions of the state were ideal for cultivating various fine grape varietals. Today, Oregon has over four hundred and fifty wineries in operation, the vast majority of which are used for the production of wines made from Pinot Gris and Pinot Noir varietal grapes, both of which thrive in the valleys and mountainsides which characterise the landscape of the state. 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.
