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. Riesling grapes have been grown in and around central Europe for centuries, and over time, they became the lasting symbol of south Germany's ancient and proud wine culture. Whilst the reputation of German wines abroad has in the past been mixed, the Germans themselves take an enormous amount of pride in their wineries, and Riesling grapes have now spread around the globe, growing anywhere with the correct climate in which they can thrive. Riesling grape varietals generally require much cooler climatic conditions than many other white grapes, and they are generally considered to be a very 'terroir expressive' varietal, meaning that the features and characteristics of the terroir they are grown on comes across in the flavors and aromas in the bottle. It is this important feature which has allowed Riesling wines to be elevated into the category of 'fine' white wines, as the features of the top quality bottles are generally considered to be highly unique and offer much to interest wine enthusiasts.
