Raw or pasteurised cow milk from cows grazed on the Kars plateaus between late April and mid-August is set with calf rennet, cut to lentil-size grains and cooked to 53–57 °C. The curd is pressed into huge wheels, salted in brine or dry salt, then ripened first in a warm room, where gas forms the eyes, and then for months in a cold room. Wheels weigh 55–85 kg and ripen 6–12 months.
Amounts from a sourceDoses from the registration per 100 L of milk. The traditional house rennet from 3 g of dried stomach is enough for about 500 kg of milk.
Cow milk from cows grazed on Kars plateaus, late April to mid-August
Raw milk accepted at no more than 0.18 % acidity (8 °SH); fat adjusted to 3–3.4 % in the industrial method[kars-gi]
Calf rennet10 ml per 100 L of milk (industrial); 100 ml per 100 L of house rennet (traditional)
The traditional house rennet is about 3 g of dried calf, kid or lamb stomach soaked in 500 ml whey at 30–35 °C for 1–1.5 days[kars-gi]
Starter culture of Streptococcus thermophilus, Lactobacillus delbrueckii ssp. lactis and Propionibacterium shermanii (industrial method only)
no starter culture in the traditional method (a few makers rarely add a piece of grated old gravyer); a culture with propionic bacteria in the industrial method

Raw or pasteurised cow milk from cows grazed on the Kars plateaus between late April and mid-August is set with calf rennet, cut to lentil-size grains and cooked to 53–57 °C. The curd is pressed into huge wheels, salted in brine or dry salt, then ripened first in a warm room, where gas forms the eyes, and then for months in a cold room. Wheels weigh 55–85 kg and ripen 6–12 months. Made in 6 steps over 5.2 months – 8.5 months. The longest step, ripen in the cold room, takes 3.5–6 months (Türk Patent ve Marka Kurumu 2024) and runs at 7–12 °C (Türk Patent ve Marka Kurumu 2024). Streptococcus thermophilus, Lactobacillus delbrueckii ssp. lactis and Propionibacterium shermanii (industrial starter); propionic bacteria make the CO2 that forms the eyes and Native non-starter lactic acid bacteria; of 120 isolates, Lactobacillus brevis (25 %), Pediococcus pentosaceus (18.3 %), L. paracasei (14.1 %) and L. fermentum (13.3 %) led do most of the fermenting.
Kars gravyer is a Turkish mountain cheese in the Swiss style, made only from summer plateau milk and ripened first in a warm room for eye formation and then in a cold room. The traditional method uses no starter culture, only milk, house rennet and, rarely, a piece of grated old cheese.
Size
Wheels 55–70 cm across, 15–17 cm high, 55–85 kg
Composition
Fat 23–42 %, dry matter 63–80 %, protein 24–34 %, salt 1–4 %, pH 5.7–6.85
Traditional method ('Geleneksel Yöntemle Üretilmiştir')No starter culture, house rennet, a 26–35 °C warm room and 4–6 months cold ripening
Industrial methodMilk may be pasteurised at 65 °C for 30 minutes and a propionic starter is added, which shortens ripening
Safety
Raw milk is accepted only at low acidity (no more than 0.18 %, 8 °SH), and the curd is cooked to 53–57 °C before months of ripening. The finished cheese is kept at 4–6 °C.
The registration says Swiss cheesemakers arriving from the Alps via the Caucasus opened the first dairy at Boğatepe village in 1890. Molokan settlers kept it going, and the Karapapak (Terekeme) Turks, who settled in Kars in 1920, carried the craft on. The geographical indication was applied for in 2021 and registered on 17 September 2024.
