In the USA, wine production is largely dominated by California, which accounts for around 85% of national volume, with renowned wine regions such as Napa Valley and Sonoma, ideal for growing popular grape varieties such as Cabernet Sauvignon, Chardonnay, Merlot and Zinfandel. The latter, often considered an American specialty, is distinguished by its rich, spicy flavors. Other states such as Oregon, famous for its refined Pinot Noir, and Washington, appreciated for its white wines such as Riesling, enrich the diversity of American wines. The United States favors fruity, bold and accessible wines, contrasting with more classic European styles. Historically, viticulture was introduced by European settlers in the 16th century, but really took off in the 20th century after difficult periods such as Prohibition (1920-1933). Today, the American market is also one of the world's largest consumers of wine, with a culture that mixes local wines with imports.
