I have posted photos from my G Adventures ‘Taste of Chile, Argentina and Uruguay’ trip taken in October 2014. G Adventures does not appear to be offering the trip currently but the details of the trip I found can be found here. The trip went from Santiago, Chile over the Andes to Mendoza for some wine tasting and cooking lessons, on to Buenos Aires and finally to Uruguay for a few days on a ranch.
