Heads turned last year when Japanese scientists announced that heating iron telluride in red wine did wonders for its conductive ability
. (They are mysteriously quiet as to how they decided to do this experiment.) Sake, white wine, and other alcoholic drinks were also, uh, sampled, but none had the vigor-inducing properties of a full-bodied red.

and summarized in the figure above, indicate that the winner is a wine made from Gamay grapes, a 2009 Beaujolais
from the Paul Beaudet winery
in France. Beaujolais are known for being acidic wines, and indeed, when the researchers did a component-by-component breakdown of the wine, testing to see which of the substances in it was the one having the effect, they narrowed it down to tartaric acid
.
