Well, it's poking its head out again!
David Derbyshire, over at the Guardian, has written an article on wine tasting and (more specifically) wine judging. Overall, it's a respectable article, but he manages to once again repeat the story about 'wine experts' not being able to tell the difference between a white and red wine.
And to make matters worse, Fiona Beckett (in a blog post reply to the article) makes a casual reference to it as well.
The story keeps going. All we can do is try to correct people one at a time.
