good article on the "napa valley of argentina"....and where hand of god wines are from.

Wow, I had no idea how big Mendoza had gotten:

The roll-call of grapes includes: Barbera, Bonarda, Cabernet Franc, Cabernet Sauvignon, Malbec, Merlot, Pinot Noir, Syrah, Tannat, Tempranillo (reds); and Chardonnay, Chenin, Pedro Xímenez, Sauvignon Blanc, Semillon, Torrontés, Ugni Blanc and Viognier (whites). A classic Argentine mix of French, Italian and Spanish grapes.

There are a lot more than Malbecs grown there.

And there are many wineries:

There are currently more than 100 actual wineries in the valley, of which around 20 are major concerns, but hundreds of brands.

The Uco Valley is an international valley, developed by outsiders – from the United States and France, to Belgium and Iran.  Whatever the explanation, most of the top producers, from O Fournier to Achaval Ferrer, Andeluna to Salentein, are foreign-owned. Of the best-known names, only Catena Zapata, Zuccardi, Mendel, Rutini and Finca Sophenia are fully Argentine.

No wonder it's one of the 8 wine capitals of the world.

Is Argentine Malbec mostly bottled as a single varietal, or in a Bordeaux-type blend?
