Eroski Dark Chocolate

The product is a dark chocolate bar from Eroski, a prominent Spanish retail brand. Based on the packaging and barcode (8480010097759), it is an own-brand product of the Eroski supermarket chain, which is part of the Mondragón Corporation.

Eroski was founded in 1969 in the Basque Country as a worker-consumer hybrid cooperative. Today, it remains one of the largest distribution groups in Spain. While Eroski designs and markets the product, the physical manufacturing is typically outsourced to specialized Spanish chocolate producers such as Cantalou S.A. or Ibercacao, which operate large-scale facilities in regions like Catalonia and Castilla-La Mancha.

As of 2026, the ultimate ownership remains with the Mondragón Corporation, a massive federation of worker cooperatives based in the Basque Country, known for its unique social and business model that emphasizes collective ownership and community reinvestment.
