The most sincere are le Portuguese, those that cheat the most are the Chileans for red wines and Canadians for whites

True or false alcohol content on the label

What is surprising is that this trick regards only wines on sale at more than 40$. But, in order; this information had worldwide coverage thanks to Wine Searcher but originally came from the  Journal of Wine Economics which published a study regarding 91.000 analysis carried out by LCBO Liquor Control Board of Ontario.  In other words it was the state monopoly for the sales of alcohol in  Ontario to do the study.

Sweet wines and Rieslings were not included.

The  LCBO analyzes  all the wines that it distributes and in the course of 18 years has collected a data bank without competitors in the world. This information  allowed  Julian Alston, Kate Fuller, James Lapsley, George Soleas and Kabir Tumber, to get  these very surprising results.
