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. Of all the New World wine countries, perhaps the one which has demonstrated the most flair for producing high quality wines - using a combination of traditional and forward-thinking contemporary methods - has been the United States of America. For the past couple of centuries, the United States has set about transforming much of its suitable land into vast vineyards, capable of supporting a wide variety of world-class grape varietals which thrive on both the Atlantic and the Pacific coastlines. Of course, we immediately think of sun-drenched California in regards to American wines, with its enormous vineyards responsible for the New World's finest examples of Cabernet Sauvignon and Merlot based wines, but many other states have taken to viticulture in a big way, with impressive results. Oregon, Washington State and New York have all developed sophisticated and technologically advanced wine cultures of their own, and the output of U.S wineries is increasing each year as more and more people are converted to their produce.
