Kasseri (Greek Κασέρι; or in Turkish kaşer, kaşar) is a medium-hard pale yellow cheese made from unpasteurized sheep milk with very little, if any, goat's milk mixed in, in Greece and Turkey. There is also a cow-milk version.
It is a soft textured, stringy rather than crumbly, chewy, hard-rind cheese and belongs to the pasta filata family of cheeses, like Provolone or Muenster. The use of fresh unpasteurized milk is necessary to obtain the correct flavor and texture, and aging of at least four months is required for the development of flavor. Aged kasseri faintly resembles Parmesan or Asiago but is not as creamy.
The name "Kasseri", produced in Greece is a protected designation of origin in the European Union.
Kasseri is consumed as is, in sandwiches, as the main constituent in kasseropita pie, or in "kasseri tiganismeno" or saganaki.
Kars gravyer cheese 
Kars is an eastern Anatolian city famous for its pastures and cattle. Kars gravyer cheese is made of high-fat cow's milk. It looks like French gruyère cheese, tastes like Swiss emmental cheese and takes a long time to produce. It usually takes 10 months to age. There are holes of 1–2 cm in the cheese, which is yellow while the rind should be darker. If the holes are both big and small and irregular, it means the cheese is not of good quality.
