Drive seven hours north of Santiago, and you'll reach the remote Elqui Valley, on the edge of the Atacama Desert. The air in this hot, dry region is some of the world's clearest (perfect for stargazing), and year-round sun and the cooling influence of the Humboldt Current (from the Pacific) are perfect for vines. "It’s like northern Italy," says Giorgio, "in that every 5 kilometers there are different conditions."
If you’ve got company coming over, this is the crowd-pleasing bottle to reach for. Planning on seafood? Alta Tierra is great with lobster, pan-seared scallops or white clam pizza (a nod to Aldo’s roots). Or go traditional Chilean with a cazuela (stew) of corn, pumpkin, pork and spices. It also hits the spot with crisp salads and a bevy of appetizers, like creamy dips and spreads.
