Delaware grapes are a small to medium-sized varietal, growing in tightly packed, clustered oval bunches. Each grape within the bunch averages around one centimeter in diameter, and the grapes have a round to oval appearance. The skin is thin, tender, delicate, and known as a slip-skin variety, which describes how the skin is easily separated from the flesh with gentle pressure. The skin is also smooth and taut, ripening from green to pale red-purple when ripe, sometimes appearing almost pink, and is covered in a white powdery bloom. 

Underneath the surface, the flesh is soft, aqueous, and succulent, containing a few to no seeds, depending on cultivation practices. These high sugar levels contribute to the grape’s sweet, fruity flavor, and there is also subtle acidity, creating a light tart and tangy aftertaste.

Delaware grapes contain vitamin A to maintain healthy organ functioning and vitamin C to strengthen the immune system while reducing inflammation. The grapes also contain potassium to balance fluid levels within the body, calcium to protect bones and teeth, B vitamins to break down fats for energy, and iron to develop the protein hemoglobin for oxygen transport through the bloodstream
