Look for cherries that have firm, plump, and glossy skin. There should be no blemishes on the fruit. Look for bright green stems. These are a good indicator of cherry health and freshness.
The best way to clean sour cherries is to simply wash them under cool water, removing any soil and dirt stains by gently scrubbing with your fingers.
Store unwashed cherries in a plastic bag in the refrigerator, and wash just before eating. Before eating fresh sweet cherries, leave them out on the counter for a few hours as the flavor is much better at room temperature. Fresh cherries should be consumed within 7 to 10 days after harvesting if stored properly.
