Like mandarins, clementines acquire their beautiful orange colour on warm days and cool nights.
The temperature difference in the Valencia region guarantees the beautiful colour and the ripening process.
The greater the contrast between daytime and night-time temperatures, the more colourful the clementine.

Mandarin and clementine: the clementine is related to the mandarin, but generally contains fewer seeds and has a sweeter flavour.
The skin of the clementine is generally thinner. In Belgium, at the height of the season, shops usually sell clementines with leaves and mandarins without.
