Here’s something special: I visited an Idiazabal cheese factory in the Basque Country and enjoyed every moment!
Yes, it is possible (and indeed, recommended) to visit a factory producing the famous Idiazabal cheese while exploring the region.
That’s exactly what I did on a recent trip, when I had the opportunity to visit the Aranburu cheese factory in Idiazabal.
The visit promised to be an authentic experience, a true immersion into Basque culture through one of its most emblematic products: Idiazabal cheese.
I admit I was curious to see up close the production process of this cheese, known for its intense flavor and distinctive smoky touch.
Additionally, I was eager to uncover the secrets that make this cheese a gem of gastronomy.
In this article, I share my experience at the Aranburu Factory and explain why I consider this visit a must-see for anyone planning a trip to the region.
If you’ve ever wondered what it’s like to witness the production of artisanal cheese, or if you appreciate good food, I believe you’ll find this account very interesting!


What is Idiazabal Cheese and Why is it Special?
Idiazabal cheese is made exclusively from raw Latxa sheep’s milk and is known for its rich and slightly smoky flavor.
Additionally, the production process strictly follows the standards set by the Protected Designation of Origin (DOP), ensuring its quality and authenticity.
This cheese originates from various regions in the Basque Country and part of Navarra, but it is Idiazabal, a small village, that lends its name to the cheese.
What makes Idiazabal so special is the combination of tradition, refined technique, and high-quality ingredients.
For centuries, Basque shepherds have been making this cheese in the mountains using methods passed down through generations.
Besides its flavor, Idiazabal is also noted for its firm texture and distinctive aroma, enhanced during the smoking process, traditionally done with beechwood.


First Impressions of the Cheese Factory
Arriving at the Aranburu cheese factory in Idiazabal felt like stepping into a world where time seems to have stood still.
Located in a peaceful area surrounded by mountains, the factory exudes a simplicity that is both welcoming and authentic.
As I approached, the distinct smell of aging cheese was already in the air, creating an anticipation that was hard to contain.
After all, I am an unconditional cheese lover!
The first part of the visit took place in a building adjacent to the factory, where I watched an informative video about the cheese and its origins.




History and Tradition: Discover the Culture Behind the Cheese
The tradition of cheese-making began with the simple goal of preserving milk but has evolved into an artisanal practice that reflects the Basque region’s identity.
So, the Aranburu cheese factory in Idiazabal is a living example of this tradition.
The family that runs it preserves ancient methods, combining them with modern techniques to ensure quality while maintaining authenticity.
During the visit, I learned that Idiazabal cheese is not just a product but a true cultural heritage.
Production starts with selecting milk, exclusively from Latxa sheep raised in the local mountains.
This milk has a distinctive flavor, resulting from the sheep’s diet and their environment. Coagulation, molding, and curing of the cheese follow traditions passed down through generations.
The final touch, and perhaps the most distinctive, is the smoking process, done with beechwood.
This practice, which started by chance, since shepherds stored cheese in the huts where they built fires for cooking and warming up, has become a hallmark of Idiazabal.


The Production Process: From Milk to Table
The first stage in cheese-making is coagulation, where milk is mixed with natural rennet and left to rest until it forms curds.
These curds are then cut into small pieces and heated slowly to help separate the whey. The resulting mass is manually shaped into molds, giving it its characteristic cylindrical form.
Then, the cheese is then pressed to remove excess whey and left to cure in rooms with controlled temperature and humidity.
The curing process lasts at least two months but can extend up to a year, depending on the type of cheese being produced.
During this time, the cheese develops its firm texture and intense flavor. The final step, which is the true secret of Idiazabal, is the smoking.
Traditionally, beechwood is used, imparting the cheese with its distinctive, slightly smoky flavor.

The Idiazabal Cheese Tasting Moment
After seeing the production process, the most anticipated moment arrived—at least for me: the cheese tasting!
I was led to a tasting room where a table was set up with different varieties of cheese.
The first impression was visual; Idiazabal cheese varies in color from ivory to golden, depending on the aging time.
I had the chance to sample cheese with different maturation periods and types of smoking. The cheese tasting was complemented by a glass of txakoli, the local wine from the region.
I noticed that the balance of flavors is impressive, clearly showing the impact of the production technique and the quality of the milk used.
Each cheese variety had its own personality, from the younger, milder cheese to the more aged and intense one.
The most aged cheese, around a year old, displayed remarkable complexity, with a persistent flavor and a slightly grainy texture that I particularly enjoyed.
It’s not a cheese for everyone, as it’s quite strong, but it was my favorite!
