The place to buy wine by the case is Parras ($ 1777 Avda. Alvear; 54-11/4814-0011; parraswines.com, a shop in Recoleta that ships worldwide. For rarer bottles—including vintages produced by the country's renowned winemakers for their own cellars—stop into Grand Cru (1718 Avda. Alvear; 54-11/ 4816-2223; grandcru.com.ar), just down the street. It has a stash of Bodega Chacra 2004, Piero Incisa della Rocchetta's sensational Pinot Noir from Patagonia. In the States this wine is sold exclusively to a handful of restaurants and an invitation-only list of collectors. A few other labels to look for:
• Noemía 2004, a terrific Malbec from Patagonia
• Yacochuya 2001, a Malbec from the north-west region of Salta
• Angélica Zapata, which makes a great white wine in the heart of Mendoza
