The Casein Plate: A Seal of Authenticity and Quality for cheeses of 10

At Quesería La Antigua, every detail counts to ensure that our products are synonymous with quality, tradition and authenticity. One of those details, perhaps unknown to many, is the casein plate that is placed on our cheeses with Denomination of Origin (D.O.). This small, but crucial, distinctive mark guarantees not only the authenticity of the cheese, but also its origin and quality, essential aspects that distinguish us in the market.

What is casein plaque?

The casein plate is a small disk or mark, generally oval or circular in shape, which is incorporated into the cheese during the manufacturing process. This plate is printed with a unique number and other identifying elements that allow the origin of the cheese to be traced and certified. Unlike a simple label, the casein plate is integrated directly into the rind of the cheese during processing, making it an inseparable part of the final product.

The role of the casein plate in our cheeses

At Quesería La Antigua, we use the casein plate to guarantee that each piece of cheese that leaves our facilities meets the standards of the Denomination of Origin. This distinctive label ensures that our cheeses are made with milk from Churra and Castellana sheep, native breeds of Castilla y León, known for the exceptional quality of their milk.

The milk used in our cheeses comes exclusively from these sheep, which not only brings a unique and characteristic flavor, but also respects and promotes biodiversity and local traditions. The casein plate, therefore, is much more than just a marker; it is a statement of commitment to quality and authenticity.

How is the casein plate placed?

During the cheese making process, the casein plate is placed on the surface of the cheese before the ripening process begins. It is inserted directly into the rind of the cheese, which ensures that it is permanently fixed. Once the cheese has ripened, the plate is visible on the surface and becomes an unalterable seal that guarantees its authenticity.

Each casein plate carries a unique number that allows the cheese to be traced from its origin to its point of sale. This is particularly important for cheeses with a Denomination of Origin, where traceability is essential to ensure that the product complies with all quality and origin regulations.

The importance of the Appellation of Origin

The Denomination of Origin is a certification that protects and recognizes the quality and unique characteristics of products originating from a specific region. In the case of our cheeses, the D.O. guarantees that they are made with Churra and Castellana sheep’s milk and that the production process is carried out entirely in the region of Castilla y León.

The casein plate is fundamental in this process, as it allows consumers to easily identify a cheese that meets all the criteria required by the Denomination of Origin. In addition, this label helps protect our customers from fraud, as it guarantees that the cheese they are purchasing is authentic and of the highest quality.

A commitment to quality and tradition

At Quesería La Antigua, our mission is to preserve and promote the cheese-making traditions of Castilla y León, and the casein plate is a key tool in this effort. Not only does it ensure that our cheeses are recognized for their quality and origin, but it also strengthens our customers’ confidence in our products.

By choosing a cheese with the casein plate, our consumers not only enjoy an exceptional product, but also become part of a centuries-old tradition that we value and respect. This plate is, in essence, a testament to our dedication to quality, taste and authenticity.


The casein plate is much more than just a badge; it is a symbol of authenticity, quality and commitment to cheese-making traditions. At Quesería La Antigua, each cheese that bears this seal is a guarantee that it has been made with the best Churra and Castellana sheep’s milk, following the traditional methods that have been passed down from generation to generation. Thanks to the casein plate, our customers can enjoy the peace of mind of knowing that they are tasting an authentic product, with Denomination of Origin, and of the highest quality.”
