Some malbecs and malbec blends I've grown very fond of recently:
2007 Cuvelier los Andes Grand Vin (Leoville-Poyferré Argentine estate)
2008 Quatro Primos, Familia Mayol (Blend of malbec, cabernet, syrah and bonarda)
2009 Quimera, Bodegas Achaval Ferrer (Blend malbec, cabernet, merlot) This is very serious wine.
2004 "Limited" Bodegas Enrique Foster.
All of these are relatively small production wines with great character.
