California grape growers and winemakers are hung up on \"hang time,\"  how long grapes should be left on the vine before picking. Some winemakers want the grapes picked late, to maximize flavor. But growers say that's cutting into their profits because they sell by weight and the longer fruit hangs the more water evaporates.
