The problem is calling those highly procesed products as being wine. I would call those wine-like drinks in the same way McD burger is burger-like product. Personally I would be worry of pesticide residues in wines. Not just those bottom cheap bottles, but from all mass and non-bio certified producers. Few years ago there was high level of arsenic found in two-buch Chunk, but it is very common across the board: "Together the 34 bottles of conventional wine contained 148 pesticide residues. All 34 bottles contained at least one pesticide, while the mean number of pesticides per bottle was more than four. The highest number of residues found in a single bottle was 10."[0]. Those traces are probably not going to kill you, but let just not see all wines as being created equal.
