Yeast on the skins

"Consider the teetotalers. They began, no doubt, by observing that some men use wine to excess - to the point at which, though the wine remains true to itself, the drinker does not. That much, I give them: Drunks are a nuisance. But they went too far. Only the ungrateful or the purblind can fail to see that sugar in the grape and yeast on the skins is a divine idea, not a human one. Man's part in the process consists of honest and prudent management of the work that God has begun. Something underhanded has to be done to grape juice to keep it from running its appointed course."

-Robert Farrar Capon in The Supper of the Lamb: A Culinary Reflection (1967), p.89
