This region has great contrasts in its geography. These orographic differences, originate an important variability of microclimates. From areas with a Mediterranean climate, to areas with classic mountain climates. This cause important difference between temperatures. It originates not only different ecosystems, but it clearly affects the type of livestock that exists in each area.
Thus in counties such as the Maestrazgo, animals such as cows, sheep or goats have a greater adaptation to the cold. That manifests itself with a lower milk production per animal, but having more fat in their milks. On the contrary, in the regions located at lower levels, milk production tends to be higher, although with slightly less fat content.
