Slip-skin grapes are a popular fruit known for their juicy, sweet flavor and their thin, easily removable skin. These grapes are commonly used for making wine and are also enjoyed as a snack. While slip-skin grapes are widely known by this name, there are several synonyms that can be used to refer to this variety of grape. Depending on the region, these grapes may be called "Concord grapes," "Niagara grapes," or "Isabella grapes." Additionally, the term "slip-skin grape" may be used interchangeably with "muscadine grape" or "scuppernong grape," both of which are similar varieties of grape with removable skins.
