My guess as to why they aren't responding to the technically illegal part is that what they are advertising and saying is 49 calories from glucose in the final product. They are not claiming only 49 calories in an entire glass. The chart posted above shows the total calories in a glass of 166. It's probably all legal and above board, just misleading, a little bit and not a number that really tells the whole story.

No,that chart is showing the glucose level not the calories. They do claim 49 calories all over thier website. There are a few places that say by glucose but most do not.include that verbiage. They than go ahead and compare their 49 calories to the calories in sweeter wines with lots more residual sugars.
I have concluded, through my probing and discussions with then that they are intentionally being deceptive.
