Waiting for grapes to ripen takes extra patience as the color matures before the rest of the fruit. Harvesting based on color alone will likely leave a bitter taste in your mouth as it takes several more weeks for the sugars to reach their peak and the tartness to subside. Waiting for the fruit to fully develop is important since grapes do not continue to ripen after harvest.
Prior to harvest look for a whitish coating on the grapes. This is an indicator of ripeness. Fully ripe grapes are usually slightly less firm than unripe fruit. Open one of the grapes and observe the seed color. Seeds of ripe grapes often change from green to brown. Finally, if all other measures indicate the grapes are ripe, do a taste test to make the determination.
Grapes can be stored for up to eight weeks at 32 degrees F with 85 percent relative humidity. They can also be processed into jams and jellies. (Cynthia Domenghini)
