Catena makes great wines, as do other large producers like Luigi Bosca and the LVMH bodegas like Terrazas de los Andes. I think its also interesting for wine aficionados to try smaller 'boutique' producers that have smaller/limited run editions of wines that are sometimes not marketed through the general channels. My experience tells me that a good wine is better when there is a story to tell (that comes with it)....
