Simon Woods recommends Montes Alpha Cabernet Sauvignon 2007 on his blog...

"Montes Alpha Cabernet Sauvignon 2007, Colchagua, Chile (£10.99 Tesco)
High class smoky French oak, some of the typical Chilean blackcurrant pastille edge, ripe but not too ripe, with a minerally backbone, firm but never aggressive tannins, still young, but very promising."
