Take notes at your tastings because wineries in Mendoza can't send cases of your favorite malbec to you. Argentine regulations allow the shipment of wine from the region only through an exporter. Two reputable companies: vinesofmendoza.com delivers boutique wines to 23 states, and southernwinegroup.com carries wines from large and small vineyards, including one of my top picks, El Lagar Carmelo Patti. Planning to fly with a few bottles? Although I unwittingly carried two bottles onto my plane, the rule is one duty-free liter—in your checked luggage.
