While the region is booming because of the popularity of its wines, it still only represents less than 2% of Argentina's vineyards. Look for appellations like Río Negro and Neuquén on the label to find great tasting Pinot Noir.

In the tiny, extreme southern region of Trevelin in Chubut, you'll find several compelling cool climate white wines like Chardonnay, Sauvignon Blanc, and Gewürztraminer.
