The area around Mendoza is great, but if you venture out a little further to the Uco Valley, there are some amazing wineries. Some of our favorites were Pulenta, Salentin, La Azul, and many more. We stayed at the most picturesque place we have ever stayed in - it's called Tupungato Divino. You will never see more stars. If you go during the summer, you can drive across the Andes to Chile and check out all that is over there. Obviously I'm the opposite of Matt and biased towards Argentina since that's where I've been
And in upstate new york - the wines around seneca and cayuga lake are surprisingly solid, especially Rieslings. Of course I'm biased there too because we had our wedding reception at Lamoreaux up there
