What is in red grapes that gives red wine such a good press?
In recent years, red wine has received some pretty good press. When we think of a healthy form of alcohol, red wine tends to be the top choice.
But why - and does it deserve all the attention?
Scientists agree that there is something in red wine that, when drunk in moderation, can help to protect the heart, reduce 'bad' cholesterol and prevent blood clots.
But there is little agreement of what is causing those beneficial effects.
Recently, Uruguayan chemists went to such great lengths to discover the secret of their healthy home-grown red wine that they sequenced the genome of the Tannat grape from which it is made.
