This cured cheese is made exclusively raw sheep's milk, which comes directly Sierra de Albarracin's own livestock of dairy sheep. The milk does not undergo any heat treatment during processing, other than that required for coagulation. This type of processing method gives this cheese a wide range of aromas and flavours typical of the native flora of the sheep milk.
Boffard 'Reserva' Cheese is made 100% raw sheep milk, according to the age-old Castilian tradition. The cheese is oiled three times with olive oil during the ageing period, which lasts at least 8 months for the large 3 kg cheese, and 4 months for the smaller 1 kg cheese. This olive oil protects the cheese during the maturing process, and provides Boffard cheese with its unique and unmistakable flavour. 20 litres of milk is needed to produce each large 3 kg cheese.
