Thanks for all the replies to my post from several months ago. I keep looking, but haven't found much of anything...only one bottle of average Rioja at Jumbo Palermo last week.
I would love it if someone does have a source for not-expensive imported wine. I'm not looking for event wines, just a little variety for dinner, parties, whatever. (And I do drink wines other than Malbec here in Argentina.) I understand the economics behind importing wines, but it's very possible to buy a good and inexpensive wine from California, Italy, Australia, or hey, Chile! Even with import taxes, it could still be decently priced.
