wine users - Sep 2011 - CellarTracker is not necessarily representative of the broad

The one thing that the authors of the paper don't happen to devote much
attention to, which I think is at least as interesting as all their other
findings, is that in general, the greater wine drinking population doesn't
think wines are as good as the major critics do. If I am understanding the data
correctly, in all cases the community rating was below all of the critics
ratings.[url]http://guesshandbagswholesale.com

This is sort of surprising, given claims by some commentators in the wine
industry that most people can't tell the difference between a $18 bottle of
wine and a $90 bottle of wine. As a result you would think that the scores that
the broader population assigned to wines might skew towards either end of the
spectrum in a kind of "yum/yuck" or "love it / hate it"
volatility.http://guesshandbagswholesale.com

Of course, CellarTracker is not necessarily representative of the broader
population, a point which the paper's authors seem to acknowledge, but it
isn't clear just how much they want to address this bias. Of course, it is
really the only broad and deep set of consumer wine evaluation data that is
publicly available, so one can hardly fault them for using it.
