A grape is a type of berry of woody vines that grows in clusters; they can be eaten raw or used to make wine, jam, raisins, vinegar, etc. Grapes are very low in calories. They are also good source of vitamins A, C, K and Carotenes. Grapes contain phyto-chemicals that have been found to have an anti-allergic, anti-inflammatory, anti-microbial, as well as anti-cancer property.
Since grapes tend to spoil and ferment at room temperature, they should always be stored in the refrigerator. Loosely wrap unwashed grapes in a paper towel and place them in an airtight container or plastic bag. This way, they'll keep fresh in the refrigerator for up to 5 days.
