The United States of America is the world’s fourth largest producer of wine and claims the world’s sixth highest acreage of land under vine.
California produces approximately 85% of all American wine, followed by Washington, New York, and Oregon. Compared with traditional wine-producing countries, the US has a large population, surpassing France in early 2011 to become the world’s largest wine consumer. Despite this, the US ranked only 62nd in per capita consumption by 2016, with just 30% of the population identifying as wine drinkers. In 2019, the US experienced its first decline in wine consumption in 25 years, as the industry lost market share to fast-growing categories such as canned hard seltzers, spirits, and craft beer. Still, the US continues to provide the world’s most substantial market for fine wines. Further, over the past 20 years, powerful American critics have had a significant influence on winemakers and markets worldwide.
In the early ninth century, the Viking Leif Eriksson brought his boat aground at L’Anse aux Meadows in Newfoundland, Canada, becoming the first European to definitively set foot on the North American continent. He christened his discovery Vinland—possibly a reference to the meadows before him or, as recounted in the 13th-century poem “Saga of the Greenlanders,” a tribute to the wealth of native grapevines. Unlike in South America, several species of wild grapevines awaited the first colonists of North America, including Vitis labrusca, Vitis rotundifolia, and Vitis aestivalis. Vitis vinifera, the source of fine wine
Please check the dates for Leaf Erikson visiting North America - it's actually about 200 years later. The Norse didn't even settle Greenland until the late 10th century. From there, they visited North America. So definitely not in the early 9th century.
Hey Alexander! Per the Encyclopedia Britannica, "According to Eiríks saga rauða (“Erik the Red’s Saga”), while returning to Greenland in about 1000, Leif was blown off course and landed on the North American continent, where he observed forests with excellent building timber and grapes, which led him to call the new region Vinland (“Land of Wine”)." What you might be referencing is the written documents of the excursion which do not appear in circulation until around 1200.
