Our milk
The quality of our products has been acknowledged at various domestic and international evaluations, where our products have received the highest awards. Being in the company of the best is a recognition of the work we do and our commitment to quality, while also strengthening consumer confidence in our brands.
Slovenian Quality

Every day, 170,000 liters of fresh milk arrive at Mlekarna Celeia from more than 600 farms in the Savinjska, Šaleška, Koroška, wider Celje, and Kozjansko regions, which is then used to make the various Zelena Dolina products.
Milk quality plays an important role in our dairy and is a key parameter in its purchasing, processing into excellent dairy products, and in strengthening consumer confidence. We are proud to source milk exclusively from local Slovenian farms. Our milk and dairy products are therefore made exclusively from Slovenian milk, produced without genetically modified organisms.
Respect for the tradition of Slovenian dairy farming and the connection with Slovenian farmers is what has guided us throughout our long history and remains the most important part of our mission today.
Traceability
Milk quality plays an important role in our dairy and is a key parameter in its purchasing, processing into excellent dairy products, and in strengthening consumer confidence. We are proud to source milk exclusively from local Slovenian farms. Our milk and dairy products are therefore made exclusively from Slovenian milk, produced without genetically modified organisms.


The story of our milk and dairy products begins at the farm. At Mlekarna Celeia, we cooperate with more than 900 domestic milk suppliers. We are proud of our commitment to sourcing milk exclusively from local Slovenian farms. Meet our milk suppliers here.
Milk is transported from the farm to the dairy in milk tankers. At the dairy, we are aware of the important role played by ensuring and understanding the quality of raw milk, which is why we check its quality at the inspection station immediately upon delivery.
Our milk and dairy products are filled in carefully selected packaging. We only use hygienic, food-safe materials that do not affect the aroma or flavour of dairy products. By the end of the shelf life of a dairy product, none of its properties may change. The story we tell on the packaging helps consumers to choose their favourite product and flavour.
We monitor quality at every step, from the farm to the actual dairy product. Our control department staff perform microbiological analyses, somatic cell analyses, and chemical and physical analyses of raw milk. Our experts closely monitor the quality of the ingredients we use in the production process. However, few people know that we carry out sensory tests on our products every day to make sure they meet our high standards before they reach the store shelves.
We ensure traceability by carefully monitoring every step of the process, from the farm to production and from the warehouse to the consumer. Our every step is recorded and 100% traceable, all the way to the final product. This allows us to ensure that consumers always get the very best. Our reward is consumer satisfaction when they treat themselves to our high-quality dairy products.
