Raw sheep or goat milk is set with rennet, the curd is pressed in cloth, crumbled and salted, then packed tight into a cleaned sheepskin (in Iran) or into terracotta pots (in Armenia). Sealed in the skin or pot, it ripens for months, slowly souring into a crumbly, salty, sharp cheese. Made in 7 steps over 3.1 months. The longest step, seal in a fresh skin and ripen, takes 3 months (Rezaei A. et al. 2020) and runs at 6–12 °C (Rezaei A. et al. 2020). Salt is 3 % (Rezaei A. et al. 2020). Lactobacilli of raw-milk Motal and Native milk flora, surface bacteria and yeasts, credited with Motal's flavour do most of the fermenting.
Amounts from a sourceTraditional process with no fixed batch size. The amounts here come from one university study that copied the Iranian sheepskin method.

What makes this one different
Motal is ripened packed into a skin bag or a sealed pot instead of as whole wheels, which keeps air out and lets the crumbled, salted curd ripen as one mass. Armenian Motal adds wild herbs and ripens in terracotta under beeswax; Iranian Motal stays plain and ripens in sheepskin.
Milk
Raw sheep milk (Iran) or goat milk (Armenia)
Vessel
Sheepskin bag (Iran) or terracotta pot sealed with beeswax (Armenia)
Ripening
About 3 months; Armenian pots can keep it over six months
Armenian Motal (Gegharkunik)Pure goat milk set with calf rennet straight after milking, pressed in cloth about 15 minutes, held in brine at least 40 days, crumbled with mountain herbs, packed into terracotta pots for 35–50 days, then sealed with beeswax and kept on ashes in cold cellars.
Iranian sheepskin MotalRaw sheep milk without starter, ripened in sheepskin bags.
Safety
Traditional Motal is made from raw milk without a starter, and one survey found Staphylococcus aureus in half its samples. ANSES advises pregnant women, young children, people over 65 and people with weak immunity not to eat raw-milk cheeses other than hard cooked ones.
Hazards the sources name: Staphylococcus aureus (found in 3 of 6 traditional samples, up to 9 × 10^3 CFU/g).
Motal is a long-standing farm cheese of north-west Iran and an age-old shepherd cheese in Armenia. Sheepskin bags were used because they were cheap, easy to prepare and let some moisture through. In Armenia, keeping food in terracotta goes back at least 5,000 years, and families still keep goat cheese in pots for winter; Slow Food made Armenian Motal a Presidium to help its makers.
