I’m interested in the so-called ‘Blue Zones’: the various pockets in the world where people seem to live longer – and more healthily – than they do elsewhere. There are about five, I think, among them Sardinia and Acciaroli in Italy, Icaria in Greece and the Nicoya Peninsula in Costa Rica. What’s fascinating is what they all have in common. The people live in small, engaged communities with very strong social ties, they walk every day, they value family life, they eat a lot of fish and plants and, most crucially for our purposes here, they tend to drink alcohol. Moderately (probably an important qualifier), but regularly. Mostly wine, and mostly red wine.
What is it, other than the obvious conviviality and sheer joie of it, that makes red wine…
