Cheese from Slovakia, the mountain part of the country
Slovenský oštiepok PGISlovenský oštiepok
Sheep milk, cow milk or a mix is set with rennet at 32–35 °C, and the curd is gathered into lumps, dipped in hot whey and hand-shaped into a large egg or cone pressed in a carved ring. After 12–24 hours in brine the cheese is hung to dry and smoked over hardwood until golden. Dairies make it from pasteurised milk with a Lactococcus culture and steam the curd at 55 °C or more.

Fresh raw sheep milk, or sheep and cow milk mixed (farm method); pasteurised sheep, cow or mixed milk (dairy method)
Sheep breeds Valaška, improved Valaška and Cigája[sk-spec]
Original culture of lactic bacteria of the genus Lactococcus isolated from Slovak sheep milk and cheese (dairy method)

Sheep milk, cow milk or a mix is set with rennet at 32–35 °C, and the curd is gathered into lumps, dipped in hot whey and hand-shaped into a large egg or cone pressed in a carved ring. After 12–24 hours in brine the cheese is hung to dry and smoked over hardwood until golden. Dairies make it from pasteurised milk with a Lactococcus culture and steam the curd at 55 °C or more. Made in 6 steps over 38 h – 4.1 days. The longest step, smoke, takes 24 h – 3 days (Industrial Property Office of the Slovak Repu…). Lactococcus does most of the fermenting.
Shaped by hand in hot whey and pressed into a carved ring, which gives it its pattern, and then brined and smoked. The PGI also allows cow milk alone, and dairy versions use pasteurised milk and a Lactococcus culture.

Dairy oštiepok is made from pasteurised milk (at least 73 °C for 15 seconds); the farm cheese uses raw milk. In a Slovak study of curd for other pasta-filata cheeses, counts of coagulase-positive staphylococci and E. coli rose during the first 24 hours, lactic cultures slowed the rise, and steaming the curd at about 55 °C lowered the counts by only 0.58 and 1.23 log CFU/g. That study did not test oštiepok.
Hazards the sources name: In 'Nite' string cheeses, a Slovak pasta-filata cheese (not oštiepok), coagulase-positive staphylococci and Escherichia coli grew in the curd in the first 24 hours; steaming cut them only by 0.58 and 1.23 log CFU/g.
The specification says written reports and family records of old bryndza makers show oštiepok was made in the early 18th century. It says the Galbavá family laid the foundations of mass industrial production, with cow milk, in Detva in 1921, and that the name entered the Lisbon register on 22 November 1967.
