(NPR) - A curious shift has happened in global wine-drinking trends: Americans have overtaken the French and Italians, Europe's traditional lovers of the fruits of the vine, as the world's top wine market. And it's not just wine drinking that's taken off stateside: U.S. wine production is also on the rise. Back in the 1970s, there were about 400 wineries in America. Today, there are more than 7,000. And they're not just in locations like Napa, Calif.; Walla Walla, Wash.; and Willamette Valley, Ore. They're in places that are less familiar as wine regions: Texas, Ohio, Hawaii and even Alaska.
