Raw goat milk is left to sour for 24–48 hours, set with rennet at 35 °C, moulded, drained and salted. The curd is layered with salt and arichi, a curd cooked out of the whey at 90 °C, inside a cleaned and salted goat skin (dariff). The closed skin is salted outside and ripens 1–6 months in a damp natural cave.

Raw goat milk is left to sour for 24–48 hours, set with rennet at 35 °C, moulded, drained and salted. The curd is layered with salt and arichi, a curd cooked out of the whey at 90 °C, inside a cleaned and salted goat skin (dariff). The closed skin is salted outside and ripens 1–6 months in a damp natural cave. Made in 7 steps over 43 days – 6.5 months. The longest step, close the skin and ripen in a cave, takes 30 days – 6 months (Hosri C 2004). Lactic acid bacteria of the raw milk, including Streptococcus thermophilus, Enterococcus faecium, E. durans, E. faecalis, Lactococcus lactis subsp. lactis and subsp. cremoris, Lactobacillus plantarum and L. curvatus does most of the fermenting.
Ripened in a whole goat skin with layers of arichi, a whey curd, and salted from the outside in a cave; the milk is soured for a day or two before renneting.
Milk
Raw goat milk from extensive mountain herds
Ripening
1 to 6 months in the skin, in a natural cave
Keeping
A 2004 project paper gives a storage life of 6 months to 1 year, so farmers sell it out of season
The milk is raw and the steps are not standardised. One study found E. coli and Clostridium in the cheese, and the project authors list poor milking hygiene, long exposure of raw milk to air and poorly cleaned skins as the main faults.
Hazards the sources name: Escherichia coli and Clostridium sp./Eubacterium tenue, detected in the cheese.
Made for a long time by farm women in the North Lebanon mountains, where the father, often a butcher, supplied the goat skins. A development project described in 2004 set out to make it more hygienic and bring it to market.
