Raw, thermised or pasteurised cow or sheep milk is set with rennet at 29–34 °C in 30–45 minutes, cut to wheat-grain size and warmed to 46–48 °C. The curd is moulded and pressed, brined 12–48 hours in 18–22 % brine, and ripened on wooden shelves at 13–16 °C for at least 60 days, ideally 90. It becomes a hard, full-fat wheel with a golden rind and a sweet, nutty, slightly piquant taste.

Raw, thermised or pasteurised cow or sheep milk is set with rennet at 29–34 °C in 30–45 minutes, cut to wheat-grain size and warmed to 46–48 °C. The curd is moulded and pressed, brined 12–48 hours in 18–22 % brine, and ripened on wooden shelves at 13–16 °C for at least 60 days, ideally 90. It becomes a hard, full-fat wheel with a golden rind and a sweet, nutty, slightly piquant taste. Made in 6 steps over 2 months – 2.1 months. The longest step, ripen on wooden shelves, takes at least 2 months (Association for the Protection of the Origin…) and runs at 13–16 °C (Association for the Protection of the Origin…). Salt is 18–22 % (Association for the Protection of the Origin…). Lactic acid bacteria from the starter or a house culture of warm-ripened milk or whey does most of the fermenting.
Livanjski sir is a hard pressed cheese that may mix cow and sheep milk and may be raw, and its curd is scalded only to 46–48 °C, below the 54–59 °C cooking heat of Gruyère. Its aroma is said to recall aromatic and spicy herbs of the milk area.
Composition

Cheeses ripened at least 6 months may carry a PREMIUM mark
Milk not cheesed within 6 hours is cooled below 10 °C and used within 24 hours. Every wheel ripens at least 60 days, and cut, packed cheese is kept below 8 °C. The milk may be raw, and a 60-day minimum does not guarantee safety. In tests that added the bacteria on purpose, E. coli O157:H7 and Listeria survived well beyond 60 days in Cheddar. A thesis reviewing these tests says many hard raw-milk cheeses aged 60 days or more have an excellent food-safety record. ANSES, the French food-safety agency, advises pregnant women, young children, people over 65 and people with weak immunity not to eat raw-milk cheese, except cooked pressed kinds such as Gruyère; this curd is only scalded to 46–48 °C.
The specification says written sources place the start of Livanjski sir in the Livno area in 1888, at the state agricultural station founded there by the government in Sarajevo under Austro-Hungarian rule. Swiss cheesemakers there introduced hard cheese from sheep milk on the model of Gruyère. It says sales were 700–900 tonnes a year in the 1970s and 1980s and 500–800 tonnes in the 2000s, with more than 80 % going to Croatia in the 2000s. The European Commission approved the name as a PGI in December 2024.
