Sonoma County winemakers are reporting significant damage to their $400 million grape crop from recent rains.

The vines have developed a rot called botrytis. One grower says he's lost 50 percent of his zinfandel vines and 30 percent of his chardonnay grapes to the fungus. To save what's left, growers are harvesting grapes with enough sugar content, spraying fungicide on fruit that need more ripening time, and clearing leaves out of canopies to let in more sunlight and wind to dry the crop.
