Latest reviews posted over at ArgentinaWineGuide.com: Finca Natalina Syrah Malbec; Fabre Montmayou Malbec; Phebus Cabernet Sauvignon.
The Fabre is excellent, crisper than many and well-structured. The Phebus is a very interesting unoaked Cab, well worth a try if light and fresh is your style. The Finca Natalina, I'm afraid, is best avoided. But two out of three ain't bad!
More reviews to be posted in the next day or two.
