The United States is known for its innovative and experimental approach to wine making. Wine is being produced in almost every State; however the leading region in terms of production is California. For every 10 bottles of wine produced in the United States 9 of them are produced in California.
Pretty much most varietals are planted in California, but the State is most well known for its Chardonnay, Zinfandel and Cabernet Sauvignon based wines, with the two most famous regions being the Napa Valley and Sonoma.
California is also one of the leading producers of Rosé wine. Other key States are New York, famous for its delicate Rieslings and Washington State with its powerful Cabernet Sauvignon and Merlot varietals, and finally Oregon, which is fast becoming one of the best Pinot Noir producing regions in the world.
