Eroski spicy sardines (sardinillas)

Eroski sardines are a staple canned fish product sold by the Spanish supermarket cooperative Eroski. Originally founded in 1969 through the merger of several small consumer cooperatives in the Basque Country, Eroski has grown into one of Spain's leading retail brands.

The product is typically sourced and packed in Spain, specifically leveraging the expertise of the Galician canning industry, although some variants may be sourced from other Mediterranean or Atlantic regions depending on supply. As a private label brand, the ownership remains within the Eroski Group (Eroski S. Coop.), which is a worker-consumer cooperative headquartered in Elorrio, Spain. This unique structure means the brand is owned by its members rather than a traditional corporate giant, focusing on local distribution within the Spanish market.
