The Difference Between Purple, Red and Green Grapes

In the market, grapes are commonly sold in three main colors: purple, red and green.

The difference between grapes is not only in appearance but also related to flavor, texture and nutritional content inside.

Maddie Pasquariello, a nutritionist working in the US, said that grapes generally have quite similar nutritional composition, providing fiber, potassium and vitamin A.

However, different colors also mean slight differences in antioxidant content, giving each one its own unique value.

Nutritionally, the difference between the three types of grapes: green, red and purple is not too big.

Purple grapes

Purple grapes are considered the most flavorful and intense. Their distinctive purple color comes from anthocyanin, a polyphenol compound that provides both pigment and anti-inflammatory properties.

Purple grapes are generally sweeter, thicker-skinned and softer-fleshed than red and green grapes.

Red grapes

Red grapes are also rich in anthocyanins and have almost the same antioxidant value as green grapes.

In terms of flavor, red grapes are considered to be slightly sweet, with a touch of sourness to create balance. The red grape flesh is crispy, the skin is thin and easy to eat, creating a sense of harmony.

Green grapes

Green grapes are pale green with a yellow tinge. Unlike red and purple grapes, green grapes do not contain anthocyanins but contain mainly flavonols, a compound that also has anti-inflammatory effects, protects the heart and nerves, and can help keep the liver healthy.

Green grapes are crunchy, fresh, and slightly sour, making them a popular grape to eat directly or use in salads.

Which grape is the healthiest?

Nutritionally, the differences between the three grapes aren't huge, says nutritionist Maddie Pasquariello.

Purple grapes have a slightly higher antioxidant content, but this benefit is not significant for overall health when included in a balanced diet. The important thing is to eat grapes regularly, rather than choosing which variety is best.
