After dinner taste some wines from Argentina's boutique vineyards at Daniel Karlin's Anuva Vinos, a wine-sourcing service and export company. Karlin runs a wine subscription club that ships hard-to-find vintages to U.S. members. Among his offerings are Argentina's famous ink-black Malbecs, including Cavagnaro's plummy 2004 Reserve and Naiara's velvety and dense 2005 Reserve.
