Mostly sheep milk is set with rennet at about 30 °C, and the curd drains in cloth bags in layers with chopped wild herbs, about 2% of the cheese weight, led by sirmo (wild chive). The slices are dry-salted for 3–4 days, washed, packed tightly into clay pots between layers of herbed çökelek and buried upside down in the ground for 4 to 7 months. A fresh version made from pasteurised milk ripens 30–60 days in brine instead.
Amounts from a sourceThe registration gives a rennet dose per volume of milk and a maximum herb share, but no full batch. Cheese is made mainly in April to June, when sheep milk and the herbs peak.
Sheep milk mainly; cow or goat milk or a mix are allowed, not skimmed or watered
Raw milk for the buried, dry-salted cheese; pasteurised milk for the fresh brined cheese[van-gi]
Rennet, bought liquid or home-made from sheep abomasum with black pepper, ginger, cinnamon, cloves, sugar and waterAbout 100 ml per 80 L of milk (traditional rennet)
Alum must not be added to home-made rennet[van-gi]
Wild herbs; required are sirmo (Allium schoenoprasum), mendo, heliz (Ferula orientalis), wild mint, kekik (Thymus migricus) and siyabo; 13 others are optionalAt most 2% of the cheese weight

Mostly sheep milk is set with rennet at about 30 °C, and the curd drains in cloth bags in layers with chopped wild herbs, about 2% of the cheese weight, led by sirmo (wild chive). The slices are dry-salted for 3–4 days, washed, packed tightly into clay pots between layers of herbed çökelek and buried upside down in the ground for 4 to 7 months. A fresh version made from pasteurised milk ripens 30–60 days in brine instead. Made in 6 steps over 4.1 months – 7.1 months. The longest step, ripen buried in the ground, takes 4–7 months (TÜRKPATENT (Turkish Patent and Trademark Offi…). Salt is 5.8 % (TÜRKPATENT (Turkish Patent and Trademark Offi…). Lactic acid bacteria, up to 7.0 log CFU/g in market Van herb cheeses and Yoghurt culture, used to sour the milk for the çökelek layered with the cheese do most of the fermenting.
Chopped wild herbs, led by sirmo, go into the curd, and the classic cheese ripens for months in clay pots buried mouth-down in the ground rather than only in brine. It is layered with a herbed çökelek made from soured, churned milk.
Composition
Average dry matter 46.78%, salt 5.73% (4.60–6.90%), protein 22.17%
Market samples
100 market cheeses from Van had pH 4.49–6.64, dry matter 49.66–65.80% and salt 5.85–11.70%
Herbs
Six required herbs and 13 optional ones; at most 2% of the cheese weight
Fresh brined otlu peynir (salamura)Made from pasteurised milk; slices ripen 30–60 days in plastic tubs of 18–21% brine at 8–16 °C and pH 4.7–5.1
Safety
The buried cheese is made from raw milk and is dry-salted and ripened for at least 4 months; the fresh brined type must use pasteurised milk. A study of 100 market cheeses found biogenic amines (for example histamine up to 469 mg/kg). Its authors judged the cheeses fit to eat overall, but they also called the histamine in about 10 % of samples toxicologically significant. Some samples carried S. aureus and coliforms. 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, which this is not.
Hazards the sources name: Staphylococcus aureus up to 2.60 log CFU/g and coliform bacteria up to 6.08 log CFU/g in market Van herb cheeses.
The registration says herb cheese has been made in Van and Hakkari for over 200 years and that Evliya Çelebi described a cheese with herbs in Van. Nomadic herders knew the wild plants well, and cheese was once made only in scattered family dairies.
