THE NAME COMES FROM THE ITALIAN WORD GRANA, A REFERENCE TO THE CHARATERISTICALLY GRAINY TEXTURE AND THE DEMONYM PADANO, REFERRING TO THE CHEESE OF THE PO VALLEY AREA OF NORTHERN ITALY.
Grana Padano is one of the world's first hard cheeses, created nearly 900 years ago by the Cistercian monks of Chiaravalle Abbey, founded in 1135 near Milan. By the year 1477, it was regarded as one of the most famous cheeses of Italy. It can last a long time without spoiling, sometimes aging up to two years. It is made in a similar way to the Parmigiano Reggiano of Emilia-Romagnabut over a much wider area and with different regulations and controls.
Like Parmigiano Reggiano, Grana Padano is a semi-fat hard cheese that is cooked and ripened slowly for at least nine months. If it passes quality tests, it is fire-branded with the Grana Padano trademark. The cows are milked twice a day, the milk is left to stand, and then partially skimmed. Milk produced in the evening is skimmed to remove the surface layer of cream and mixed with fresh milk produced in the morning. The partly skimmed milk is transferred into copper kettles and coagulated; the resulting curd is cut to produce granules with the size of rice grains, which gives the cheese its characteristic texture, and then warmed to 53–56 °C (127–133 °F). It is produced year-round and the quality can vary seasonally as well as by year. Though similar to Parmigiano Reggiano cheese, the younger Grana Padano cheeses are less crumbly, milder, and less complex in flavor than their better known, longer-aged relative.
On an annual basis, the Grana Padano consortium exports € 750 million of their product around the world.
