Description
Varying in color from deep blue to purple to almost black, the large round Concord grape is encased in a rather thick skin. The flesh offers a medium-sweet flavor with a slight tart tang. Very seedy, the juicy pulp is distinctively musky. A powdery film characteristic of grapes is produced by cells in or near the surface that form a natural waterproofing and also prevents their skin from cracking.

Storage Temperature
· Temperature: 32 F, 0 C
· Relative humidity: 85 percent
· Mist: no
· Typical shelf life: 56 to 180 days
· Odor producer. Grapes fumigated with sulfur dioxide will produce odors that may be
absorbed by other fruits and vegetables. Do not store or transport fumigated grapes
with other fruits and vegetables.
· Odor sensitive. Grapes will absorb odors produced by leeks and green onions.
· Moderately sensitive to freezing injury. Although frozen grapes are a good snack,
freezing is a poor method of storage.
· White or green grapes will have a yellow cast or straw color with a touch of amber at
their taste peak. Red varieties are best when red coloring predominates all or most of
the berries.
· Darker varieties should be free of a green tinge.
· Minimize shatter by unfastening the lug?s lid. Hold the lid on top while turning the lug
upside down. Carefully remove the lug. If lined, the grapes will stay in place. Remove
the liner and the grapes will fall free.
