If it rains when they're picking, what happens is that the grapes, because of the moisture and such, it will be a thinner wine and there will be a tinsy for more rot and all these are reflected in the wine itself. You need great grapes to make great wine. A great wine maker cannot make greatness unless he has the materials to work with. If he has great grapes he can muck it up. But if he has a great winemaker and he has lousy grapes there's not much he can do.
