Mleczna Dolina Kefir Naturalny

Mleczna Dolina is a popular dairy brand specifically created for and sold through the Biedronka supermarket chain in Poland. This specific product, Kefir Naturalny, is a traditional fermented milk drink known for its probiotic properties and 2% fat content. The product is manufactured within Poland, often using local Polish milk suppliers to ensure freshness and competitive pricing.

The brand is a private label owned by Jerónimo Martins, a Portuguese corporate group that operates the Biedronka chain. While the products are deeply rooted in the Polish market and culture, the ultimate corporate management and financial ownership reside in Lisbon, Portugal. This model allows the brand to maintain a local identity while benefiting from the logistical and financial scale of an international retail giant.
