Look for: A bright, clean appearance and a uniform good color for the species. The individual small cells making up the berry should be plump and tender but not mushy. Look for berries that are fully ripened, with no attached stem caps. Avoid: Leaky and moldy berries. You can usually spot them through the openings in the ventilated plastic containers. Also look for wet or stained spots on wood or fiber containers, as possible signs of poor quality or spoiled berries.
