The story of Okręgowa Spółdzielnia Mleczarska in Sierpc is a tale of passion, craftsmanship and dedication to quality that has lasted for nearly 100 years. It all began in the 1920s when local farmers and dairymen from the Mazovia region decided to join forces and create a community based on cooperation, mutual trust and respect for nature. This was how the dairy cooperative was born, which over time grew into a strong brand recognised throughout Poland today – OSM Sierpc.

Thanks to consistency, honest work and openness to innovation, our cooperative has continued to develop. Over the years, we have refined our recipes and technologies without losing what is most valuable – the artisanal approach to cheese production. Today, OSM Sierpc boasts modern production facilities, new standards in logistics and sales, but still holds to the same philosophy: flavour is more than a sense and more than pleasure.

The secret of flavour is the highest quality raw materials and respect for the production process

The success of our products is no accident. The taste of OSM Sierpc cheeses depends on many factors, the most important being: the highest quality milk, carefully developed recipes, and the cheesemaker’s attention to ensuring every single step of production follows strictly defined standards.

The milk used to produce our cheeses comes from trusted suppliers – local farmers with whom we have cooperated for years. We understand the importance of animal welfare and the environment in which they live – that is why we choose milk from clean areas where farming is carried out sustainably, without haste and with care.

The production process is overseen by a team of experienced technologists who rely on knowledge passed down through generations. In our facilities, tradition goes hand in hand with modernity – we use innovative technologies that allow us to take even better care of quality and food safety. Thanks to this, OSM Sierpc cheeses retain their natural flavour, perfect consistency and long freshness.

Cheese that brings generations together

OSM Sierpc products have been present on Polish tables for years. Regardless of region, age or lifestyle – our cheeses accompany people both during everyday meals and special occasions. For some, it is the taste of childhood; for others, a guarantee of quality and a reliable choice. Sierpc cheeses are found in school lunchboxes, on sandwiches at family dinners, on elegant cheeseboards, and in baked dishes prepared for Sunday lunch.

Cheeses from Sierpc bring generations together. These are products that naturally fit into the rhythm of life – accompanying us from early childhood through to adulthood. What lies behind the phenomenon of these cheeses? Their versatility and timelessness. They work equally well in simple, classic combinations and in modern cuisine, wherever flavour, authenticity and quality matter.

Why do consumers choose OSM Sierpc cheeses?

In a world where time is often scarce and food product offers become increasingly anonymous, it is worth reaching for what is certain, proven and made with passion. By choosing OSM Sierpc cheeses, you choose not only excellent flavour but also the values behind our brand.

Our cheeses are made exclusively from natural ingredients – without preservatives, artificial colours or compromises. We care about transparency and honesty at every stage of production – from milk, through the recipe, to the final packaging. Every piece of cheese is the result of the work of people who truly love what they do.

OSM Sierpc also stands for responsibility – both towards the environment and the local community. We support Polish farmers, care about sustainable development, and invest in innovations that allow us to produce better, smarter and with respect for nature.
