There is nothing but flavor being infused into the Fuji apple. The apple takes on no additional sugars or calories. They are not genetically altered in any way. The apple is as healthy as ever but now has the new exciting grape flavor.
So simply put, how do Grāpple™ brand apples get their flavor? Fuji apples are dipped into a combination of pure water and Concord grape flavoring for a short time. They are then moved into cold storage for few days while the flavor takes hold. After which they are packed and shipped out to grocery stores.
