Kefalograviera PDOΚεφαλογραβιέρα
Sheep milk, or sheep milk with some goat milk, is set at 32–34 °C, and the curd is broken up and reheated to about 48 °C. The pressed wheels rest a day, sit about two days in strong brine and are dry-salted on the surface about ten times while they ripen. A second, colder stage below 6 °C brings the total to at least three months.
No fixed amounts recordedThe PDO summary fixes temperatures and times, not amounts. In one dairy make, 40 L of pasteurised sheep milk gave 6 wheels of 1.1 kg (Tzora et al. 2022).

At a glance
Sheep milk, or sheep milk with some goat milk, is set at 32–34 °C, and the curd is broken up and reheated to about 48 °C. The pressed wheels rest a day, sit about two days in strong brine and are dry-salted on the surface about ten times while they ripen. A second, colder stage below 6 °C brings the total to at least three months. Made in 6 steps over 3.1 months. The longest step, finish ripening cold, takes at least 3 months (Greek Ministry of Agriculture) and runs at up to 6 °C (Greek Ministry of Agriculture). Salt is 18–20 % (Tzora A. et al. 2022). Levilactobacillus brevis and Enterococcus faecium dominating early ripening, and Weissella paramesenteroides and E. faecium late, in artisanal cheese made without starter and Commercial starter of Lactococcus lactis subsp. lactis and cremoris, Streptococcus thermophilus, Lactobacillus bulgaricus and Lactobacillus rhamnosus do most of the fermenting.
The name joins kefalotyri and graviera. Its curd is reheated to about 48 °C, and after two days in brine the rind is dry-salted about ten times. It then finishes ripening in the cold, below 6 °C.

Dairy KefalogravieraPasteurised milk and a commercial starter
Safety
In artisanal Kefalograviera made without starter, sampled early and late in ripening, Staphylococcus aureus stayed below 2 log CFU/g, and E. coli O157:H7, Listeria monocytogenes and Salmonella were absent. That was one sample at each stage, so it does not show that any batch is free of them. The study's milk was raw. ANSES names Listeria monocytogenes, Salmonella and enterohaemorrhagic E. coli as hazards of raw-milk cheeses and tells pregnant women, young children, people over 65 and people with weak immunity to avoid them, apart from cooked pressed kinds such as Gruyère.
The Greek application summary (Ministerial Decision 313032/11.1.94) says Kefalograviera came into production over recent decades and had become widely known in Greece. The name was registered as an EU PDO by Commission Regulation (EC) No 1107/96 of 12 June 1996. Tzora and colleagues (2022) describe it as one of the most widespread cheeses in Greece, with annual production of around 3000 tons.
