Having experienced this in my backyard for the last 20 years, I would wager
a guess that your grapes have "brown rot," a generic term for the plant's
reaction to any number of fungal invaders. It's followed by browning and
then raisin-ing of the grapes, a few at a time, spreading by rain splash.
If it's only on a few leaves, cut them off and dispose of them in the
trash, NOT compost. Early spring (pre-bud) application of either a dormant
oil or lime sulfur spray does the trick. Clean up ALL leaves in the fall
and dispose of them far, far away.
