Argentina ranges from the Andes to the Atlantic, from the subtropical north to the sub-Arctic south. Within its vast geography, as mid-19th-century European immigrants discovered, there are great places to grow grapes. But it wasn't until 2002, when producers began exporting in earnest, that the rest of us got to taste what Argentines had been drinking all along. Argentina now sends nearly 7 million cases of wine to the U.S. yearly, most of it just one varietal: malbec. Big, dark, and often affordable, malbec has appealed to wine drinkers used to rich California reds. In recent years, though, tastes have changed, and Argentine vintners are responding with new ways of making their wines. Here are seven categories of Argentine wine that you'll want to taste now.
