Pecorino — Italy's Ancient Sheep Cheese Family
What it is
Pecorino is the collective Italian name for cheeses made from sheep (pecora) milk. It is not a single cheese but a family of cheeses produced across a wide arc of central and southern Italy, each with distinct character, production methods, and local significance. The major varieties include Pecorino Romano (Lazio and Sardinia), Pecorino Sardo (Sardinia), Pecorino Toscano (Tuscany), Pecorino di Filiano (Basilicata), and Pecorino Crotonese (Calabria), among many others with smaller-scale production. Together they represent the most diverse sheep cheese tradition in Europe.
History & domestication
Pecorino Romano is specifically the most ancient of the family with documented history. Roman sources — including Varro (Rerum Rusticarum, 37 BCE), Columella (De Re Rustica, 65 CE), and Pliny (Naturalis Historia, 77 CE) — describe in technical detail the production of pressed, salted sheep milk cheese in the Roman countryside. The cheese fed Roman legionaries: its high salt content provided a dietary supplement necessary for soldiers undertaking hard physical labor in hot climates, and its durability (a well-made aged Pecorino Romano can last for years) made it ideal for military provisioning. The daily ration of a Roman soldier on campaign included a portion of Pecorino Romano.
The production of Pecorino Romano in the Lazio countryside — the Agro Romano surrounding the city — was so central to Roman food supply that its production and trade were regulated by municipal authorities. As the Roman Empire declined and the city's population shrank, production of Pecorino Romano shifted to Sardinia, which by the early modern period had become the dominant production zone. Today, despite the name, most PDO Pecorino Romano is produced in Sardinia from Sardinian sheep milk, with only a small proportion produced in Lazio proper.
Varieties and flavor profiles
Pecorino Romano is the most assertive of the family: hard, intensely salty, sharp, with a strong lanolin-forward sheep milk character. Its saltiness is partly functional (it was a dietary salt source for legionaries) and partly preservative (salt inhibits unwanted microbial activity during aging). It is used primarily as a grating cheese — the specific partner to Pasta all'Amatriciana, Cacio e Pepe, and Pasta alla Gricia. Its flavor is "louder" than Parmigiano-Reggiano and incompatible in its assertiveness with delicate preparations; in the hands of a Roman cook it is a defining flavor element.
Pecorino Sardo comes in two forms: dolce (young, aged less than 60 days, mild and semisoft) and maturo (aged more than 2 months, firmer, with a more intense flavor). Sardinian cooking — which is among the most ancient and autonomous regional cuisines of Italy — uses Pecorino Sardo in dishes like Culurgiones (the distinctive Sardinian pasta parcels with a sheep cheese, potato, and mint filling, sealed with a characteristic wheat-sheaf pinch).
Pecorino Toscano, the mildest of the major varieties, is produced in the Tuscan countryside and Maremma region. Its PDO versions include a fresh (less than 20 days) and a semi-aged (at least 120 days) form. It is eaten young on bread with broad beans (fave e pecorino — the classic Tuscan spring pairing), and aged with honey or pears.
Culinary significance
Pecorino Romano's culinary significance in Roman cooking cannot be overstated. The four canonical Roman pasta preparations — Cacio e Pepe, Carbonara, Amatriciana, and Gricia — all use Pecorino Romano as their primary or sole cheese. In Cacio e Pepe (literally "cheese and pepper"), the cheese is the dish: finely grated Pecorino Romano emulsified with pasta cooking water and black pepper into a sauce of extraordinary simplicity and precision. The cheese must be the right variety (Romano, not a milder sheep cheese), at the right temperature, added with the right amount of starchy pasta water, for the emulsification to succeed without clumping. It is a dish that looks humble and cooks like a chemistry experiment.
