Stale bread will not make you sick. Chefs use it in recipes for croutons, breadcrumbs, etc. as long as there is no mold. Stale just means it's lost it's moisture. If it tastes OK to you, then eat up! = ) twofunnyboxers Â· 10 years ago.
Color. While knowing when to harvest Concord grapes is more about taste than color, Concord grapes will turn a telltale darker shade two to three weeks before peak harvest. The color can vary depending on where it is grown, with the standard deep blue-purple color slightly lighter in colder areas and darker in warmer climates.
All types of grapes come in a variety of colors. While green, red, and black are the most commonly consumed color varieties in the U.S., grape colors also include amber/yellow, blue black, crimson, pink, and purple. (Although you may also hear the color white being used to refer to grapes, white grapes are actually green in color.)
