My wife and I are visiting Mendoza for four days this March. it will be our first time in Argentina.
For the majority of our time in Mendoza we would like to focus on wine tasting. I have the info on two well-reviewed drivers, who I'm sure know what they are doing, but I would also like some independent advice.
I visit Napa and Sonoma regularly (sample tasting report here: http://chowhound.chow.com/topics/813883) and have been to tastings in many other places. So, our real focus is the wine - not the tourist experience of a "tour" or a high-end property. We want to try the best wines, ideally by smaller producers who don't export much, from the best producers. If that means a lovely property, great, but that is not the focus.
I can't admit to having very deep knowledge of Argentine wine at all. I could name a handful of bottles I buy regularly and a few of the big producers like Catena, but I really don't know much.
If anyone has been and has particular producers they'd recommend, or other ideas, your help would be most appreciated.
