We will tell you all the secrets of Idiazabal cheese: Its history, its preparation, its characteristics, its identification ... Everything you want to know about Idiazabal, here. Let’s start!

1. History of Idiazabal cheese

Idiazabal cheese is one of the most characteristic hallmarks of the Basque Country and Navarra. This unique and appreciated cheese is with latxa and carranzana sheep milk. With black faces and long fleeces, these breeds have always been indigenous to the Basque mountainous landscape.

Throughout its history, its breeding has varied minimally. Even today, the shepherds use the old routes defined by the changes of seasons to take advantage of the food of their flocks. During spring, summer and autumn, mountain pastures. During winter, they descend into the valleys.

This respect for the ancestral way of life contribute to the manufacturing of this cheese. It is respectful with the environment, helping to maintain it and employing hundreds of families that still live in rural and mountain areas.

The differences in the pasture, the climate and the special touch of the cheesemakers, lead to the different aromatic nuances, which are characteristic of Idiazabal: a cheese respectfl with its traditions and history.

As a curiosity, the Idiazabal cheese receives its name from the small town near the Aralar Range. Nowadays, the Interpretation and Tasting Center is located. Everything about this cheese is taught there.

2. Idiazabal cheese elaboration

To make a kilo of Idiazábal cheese, you need around seven liters of whole sheep's milk, raw and unpasteurized, which will be gently heated in stainless steel tanks up to 30ºC.


The natural rennet will be added to the milk, and it will take about 30 minutes to obtain a compact curd. It will be cutted into pieces the size of a corn kernel.

To make it easier to evaporate, and to preserve the fat and proteins. The temperature of the tank will be raised to approximately 37º C.


Once the compact curd and the cheese have hardened enough, the heating will be stopped and the resulting curd will be put into molds, where it will be pressed to extract the whey that still remains.

Once the extraction is finished, it will be brined for 24 hours. Once there, the cheeses are marked with their distinctive number.


As a result, we will obtain a hard pressed cheese. It usually has an average size of three kilos per piece, which will be refined at a temperature of 10º C in ripening chambers where the humidity rises up to 90%.


Throughout this process the acidity will increase and will help its conservation. Maturation period lasts around two months. Although usually it lasts between 4 and 8 months. (This may vary depending on the cheese maker).

The smoking of the Idiazabal cheese is the final touch, it is optional and takes place at the end of maturation. This practice is characteristic of Urbasa and Entzia, not found in other localities. The wood used and the smoking time will rise to different organoleptic characteristics.


Once the cheese production has finished, it is collected in the factories, and it will be verified that its composition corresponds to that of an Idiazabal. Likewise, it will be verified that it accomplishes  hygienic-sanitary regulations and that it exceeds the rigorous analysis carried out by the Official Tasting Committee of the Denomination of Origin Idiazabal.


Once all the tests have been done, it will be ready for the purchase. We can find it in whole pieces or pieces, and in its two versions: the smoked one and the normal one.

Its flavor is intense, with a marked character of matured sheep's milk, with a spicy touch and medium salinity. 


We highlight its high calcium content, which makes Idiazábal cheeses suitable to prevent osteoporosis.

Though certain producers maintain a pulse to introduce other species, the administration is firmabout the type of sheep that should be used to produce this cheese.

Its headquarters are in Ordizia, in the Gohierri of Gipuzkoa. Each year, one of the most important cheese competitions is held every year.

8. Ordizia Latxa Sheep Contest

And when we talk about one of the most important cheese competitions, we are indeed referring to the Ordizia Latxa Sheep Competition. It is celebrated every year on the first Wednesday in September in Ordizia, a small town in Gipuzkoa located by the Oria River. The idiazabal is a claim to the best palates, who after deliberations will award their prize to the perfect piece.

Before the contest begins, the cheeses are splitted in half. One half will be used for the tasting by the experts, and once the winner is chosen, the other half awarded will be auctioned.

Among the experts are the best-known Basque chefs: Arzak, Berasategui, Subijana, Arguiñano ... They have undoubtedly contributed to the prestige of the contest, and to make Idiazabal known by incorporating it into their dishes.

As a curious fact: In the contest held during 2020, the company with the highest bid was a motorcycle dealer in Donostia, which paid 9,200 euros for less than two kilos of idiazábal cheese. But this was not the highest price, which reached 13,050 euros in 2014.

The contest has changed since its early years. Once the trophy was won, it was taken to a restaurant and then turned into small pieces or slices for tasting in their living room.

Nowadays, we speak about a whim, the auction and therefore its winner will have media coverage for days.

And so will the shepherd graced with the award for the best Idiazabal cheese. He will not sell the batch of the award-winning cheese and the whole production in a few hours.
