Grāpple ( /ˈɡreɪpəl/ gray-pəl) is the registered brand name for a commercially marketed brand of Fuji or Gala apple that has been specially treated to make the flesh taste like a Concord grape.
A Grāpple is created by infusing an apple with a concentrated solution of natural and artificial Concord grape flavor and water. This solution does not add additional sugars or caloric content, nor does it affect the nutritional value of a standard apple. All ingredients are USDA and FDA approved and the process has been licensed by the Washington State Department of Agriculture.[1] Contrary to what the name implies, it is an externally flavored fruit product, not a true hybrid of two fruits.[2]
