Couple of thoughts about sweet wine...a small commercial winemaker near me told me that sugar is good since it covers a variety of wine flaws. So it may not only be something that the consumer wants, it may be something the commercial winemaker is deliberately doing to cover up flaws in the product. There is no doubt that the wineries in MO produce some pretty good wine but where they make their money is from the sweet wine...sweet wine is what sells around here. As far as knowing what you are drinking, I agree with Greg...this really just applies to average consumers in the store. The folks that know wine can ace these blinded taste tests. A good friend of mine has a local restaurant. We had a blinded wine tasting party with 10 different varietals and he nailed every single one. Not just red/wine/rose, but every single varietal. I'll bet lots of folks on this forum could do same.
