Known for their juiciness, Valencia oranges are perfect for making orange juice. They have a thinner skin compared to navel oranges and contain more seeds.

These have a distinctive red or maroon flesh, which is a result of anthocyanins, a type of antioxidant. They have a unique flavor profile, often described as a mix of orange and raspberry.

4. Mandarin Oranges: 

Smaller and less acidic than other varieties, mandarins are easy to peel and are often enjoyed as a snack. They include tangerines, clementines, and satsumas.
