Buy It All!!
I don't know how these guys do it. They produce the best wine for a quality:price ratio for a wide range of varietals and blends over the several years I have been drinking them. The Finca Flichman Expresiones Reserve Shiraz-Cabernet 2004 from Argentina is simply put a superb wine - a $15.75 "wow" of an effort. It has a beautiful plush mouthfeel, intense but complex flavours, yummy soft tannins....an open bottle sure doesn't last long. The only criticism I have is that is clocks in at a whopping 15% alcohol, which limits the amount you can enjoy.
I also picked up the latest release of their Reserva, Malbec, oak aged, 2005 which is a fine effort itself, but not as complex and plush as the expresiones. This is a solid "good" wine, also excellent value at $12.95.
