The wheels of Parmigiano Reggiano are arranged in long rows and left to rest on wooden tables. In this way the outer part of the cheese dries to form an untreated natural rind that is entirely edible. Ageing lasts for a minimum of 12 months and it is at this point that only those wheels that pass a selection continue ageing for 24 months or more. The experts esperti del Consorzio di tutela examine each wheel of Parmigiano Reggiano and only after they give their approval are the wheels PDO branded Denominazione d’Origine Protetta (DOP). All marks and the dotted script are removed from those wheels that do not meet the PDO requirements. Time transforms the cheese; during ageing, Parmigiano Reggiano acquires its typical granular texture with its characteristic flaking fracture pattern and becomes friable and soluble. The ageing process confers extraordinary characteristics upon Parmigiano Reggiano which differ in relation to the length of the period of maturation. For this reason a system of colored stamps has been introduced to assist consumers in the choice of products by identifying the various stages of ageing of Parmigiano Reggiano.

RED STAMP – Aged for over 18 months

Parmigiano Reggiano boasts a unique and remarkable history dating back nine centuries and is still today made in the same places and with the same techniques.

The origins of this cheese lie in the Middle Ages, generally placed around the 12th Century. The first cheese houses appeared in the Benedictine and Cistercian monasteries of Parma and Reggio Emilia: thanks to the abundance of water courses and ample pastures, this circumscribed area of the Emilia region soon saw the spread of production of a hard cheese, obtained via the scalding of the milk in large vats.

Parmigiano Reggiano is still made today using the same ingredients as nine centuries ago, in the same places and in the same highly skilled manner. The master cheesemakers continue to produce this cheese with high quality milk, natural rennet, salt and no additives, by hand and with the same passion and integrity. The recent history of Parmigiano Reggiano is represented around 380 small traditional cheesemaking firms in the designated area, representing around 3,500 milk producers who have obtained legal recognition of their determination to conserve unaltered the production methods and the extremely high quality of their cheese.
It is the story of how the guarantee of the genuine qualities of Parmigiano Reggiano is today absolute thanks of precise regulations, applied with strict self-discipline and rigorous controls.

Parmigiano Reggiano is a cheese that has been safeguarded for over 70 years by the Consortium for its protection and loved for over nine centuries for its ever generous flavor.

Parmigiano is born out of its territory and the skills of the people who make it. It is made today just as it was nine centuries ago: the same ingredients (milk, salt, rennet), the same care and passion and the same area of origin.

The production of the milk and its transformation into cheese take place in the provinces of:
Parma; Reggio Emilia; Modena; Bologna, to the left of the River Reno; Mantua, to the right of the River Po.
There is, in fact, a concentration of over 3,500 agricultural firms producing quality milk and the over 380 cheesemaking firms that transform it every day and that age the cheese for a minimum of 12 months through to two years and over, day after day.

Registered livestock farms

Parmigiano Reggiano is produced exclusively in the provinces of Parma, Reggio Emilia, Modena and parts of the provinces of Mantua and Bologna, in the plains, hills and mountains enclosed between the Po and the Reno: here are found the farms on which the cattle are raised on fodder produced in the area. The feeding of the animals is strictly regulated to prevent the use of ensiled or fermented fodder.

Milk processing

Parmigiano Reggiano is made with the skimmed milk of evening milking added to the full milk from morning milkings. Poured into the typical copper vats with the shape of overturned bells, the milk is enriched with natural rennet and the starter culture: in this way the coagulation takes place. The curd is fragmented by the master cheesemaker into miniscule granules using a traditional stirrer known as a spino. This operation is followed by a slow scalding phase that reaches 55°C, after which the curd granules precipitate to the bottom of the vat, forming a single mass that is extracted by the cheesemaker and molded to form the wheels of cheese. Around 600 liters of milk are required for each wheel.

Marks of origin

Each wheel is assigned a casein plaque with a unique and progressive number: this is the Parmigiano Reggiano PDO identity card. With a special branding mold fascia marchiante the wheels are incised with the month and year of production, the registration number of the cheese house and the unmistakable dotted script around the full circumference.


After a few days the wheels are immersed in a saturated solution of water and salt: this is salting by osmosis. This final phase concludes the production process for Parmigiano Reggiano and is followed by that of ageing stagionatura.

Parmigiano Reggiano contains only 30% water and no less than 70% nutritional substances: for this reason it is a cheese extremely rich in protein, vitamins and minerals.

Healthy, tasty and digestible

Parmigiano Reggiano is rich in essential and easily assimilated amino acids thanks to the presence of enzymes that modify the casein and make it highly digestible: for this reason is also recommended for those intolerant of proteins from cows’ milk. It is also characterized as a lactose-free* food. The absence of lactose is a natural consequence of the typical Parmigiano Reggiano cheese making process. It contains galactose in a quantity of less than 0,01g/100g.

Rich in calcium and nutritional substances

No less than 16 liters of a high quality milk from the area of origin are required to produce a kilo of Parmigiano Reggiano. A nutritional charge of proteins, vitamins, phosphorus and calcium that concentrates in the curd and remains alive during the long period of ageing. Natural ageing makes Parmigiano Reggiano easily digested and allows it to develop a complexity of extraordinary aromas and flavors.

Good for all ages

Parmigiano Reggiano is a perfect ally for health and psycho-physical wellbeing. Rich in nutritional substances it is indispensable for children’s growth, the health of adolescents and the elderly and to provide ready energy for those practicing sport.
