There's a wine bar in town that does both tastings and helps with arrangements for visiting the establishments. If off the beaten path, we actually had rather a good time in Cafajate, which is a one-horse town in the best sense of the word, and very good for Torrontes.
Please note that Cafayate is in Salta.... this is a plane ride away from Mendoza. We are talking about two different provinces here.
Distances in Argentine wine country can be daunting.... even inside Mendoza, getting from one producer in Lujan de Cuyo to another in the Valle de Uco can be a 3-4 hour car drive. It pays to do homework before and figuring out what you want to visit and plan well ahead.... also, reservations are a must in 99% of all bodegas, unless you are ok with getting the cookie-cutter experience.
