Traditional Portuguese Cheeses

Traditional Portuguese cheeses are among the oldest and most refined expressions of the country’s food culture. They result from pastoral know-how passed down over centuries — from herding to milking, from milk coagulation to patient curing in cool, humid environments. More than gastronomic products, they are living memories of a rural economy based on sheep, goats, and cows, and an inseparable part of Portuguese intangible cultural heritage. Today, over a dozen of these cheeses hold Protected Designation of Origin (PDO), a European recognition that ties each cheese to a territory, native breeds, and specific techniques.

The cardoon flower and sheep cheeses

The great originality of Portuguese cheesemaking lies in the use of the cardoon flower (Cynara cardunculus) as a coagulant. Unlike most European cheeses, which use animal rennet, the main sheep cheeses from central and southern Portugal coagulate the milk with the dried stigma of this plant. This results in a characteristically soft and buttery paste, with a slightly bitter and spicy note.

The pinnacle of this family is Queijo Serra da Estrela, often considered the oldest and noblest of national cheeses. It is produced mainly between November and March, from raw milk of Bordaleira Serra da Estrela and Churra Mondegueira sheep, and its curing lasts for dozens of days until it reaches the semi-liquid texture served with a spoon. In the same lineage are Queijo de Azeitão, from the Setúbal Peninsula, and the Alentejo cheeses of Serpa, Évora, and Nisa, all made from sheep’s milk and vegetable coagulation.

Coagulating milk with a flower instead of animal rennet is an extremely rare practice in Europe — and it is precisely this that gives Serra and Alentejo cheeses their unmistakable buttery paste.

Goat, cow, and the diversity of territories

Beyond sheep, Portugal’s geography has shaped traditions with other milks. In inland Trás-os-Montes, Queijo de Cabra Transmontano and Queijo Terrincho — the latter made from Churra da Terra Quente sheep — reflect the pastoralism of the Northeast highlands. In the center, Queijo Rabaçal combines sheep and goat milk, inheriting the aromas of the region’s aromatic herbs around Penela and Soure.

In the Azores, cheesemaking takes on a distinct island character: Queijo São Jorge, made from raw cow’s milk, was born in the lush pastures of its namesake island and is historically linked to the Flemish community that settled the archipelago from the 15th century. It is joined by Queijo do Pico, also made from cow’s milk, with a soft paste and intense flavor. This diversity of milks and methods is rooted in the ways of life of transhumance and pastoralism and aligns with the values of the Mediterranean Diet, recognized by UNESCO.

A know-how in transmission

The continuity of traditional cheeses depends, as it always has, on the transmission of gestures difficult to codify: evaluating the milk, dosing the cardoon and salt, turning and washing the cheeses during curing. PDO protects these practices against industrial imitation, but their future also hinges on the survival of native breeds and small-scale pastoralism. Alongside other food heritages, such as cured meats and sausages, traditional cheeses form an essential chapter of intangible heritage — a taste of place that resists standardization and keeps alive the rural landscapes that gave rise to it.
