Caseificio Sociale Castellazzo, one of the pioneering cheese transformation facilities in Reggio Emilia, stands as a testament to tradition and quality in the Parmigiano Reggiano industry. Annually, the factory processes 80,000,000 kilos of milk to produce approximately 18,000 wheels of the renowned cheese.

With a state-of-the-art production plant and modern storage facilities, Castellazzo ensures that its products meet rigorous quality standards. The factory’s commitment to excellence has been consistent throughout its long history, supporting hundreds of local producers and sustaining small livestock farms dedicated to milk production for Parmigiano Reggiano.

The factory has achieved significant milestones, including being among the first in the province to secure the Quality Management System certification according to UNI EN ISO 9001 standards. This dedication to quality is reflected in every wheel of cheese produced, embodying the simplicity and authenticity essential to Parmigiano Reggiano—made with just milk, salt, and rennet.

For over 100 years, Caseificio Sociale Castellazzo has been transforming the finest milk into a unique and exquisite cheese, driven by the values of hard work, effort, and the certainty of doing things right. Every day, this tradition continues as milk is collected twice daily from select cows, ensuring the highest quality in every step of the cheese-making process.
