$10 bottle from one area is not comparable to $10 bottle from different area. There are regions where you can get good quality for $10 (a lot of Hungarian regions) and where $30 is just entry level bottle (say, Burgundy). I am sure a lot of people will be able to say difference between $10 and $100 bottle given you are tasting wine from same area and the wine is in same style.
